noreply@blogger.com (CouHome) — Fri, 23 Aug 2024 16:37:00 +0000

To understand their significance, it's essential to ask: How does a mag lock system work? At its core, a mag lock system operates through the interaction of an electromagnet mounted on the door frame and an armature plate attached to the door. When electricity flows through the electromagnet, it generates a magnetic field that attracts the armature plate, securely locking the door. This system is not only effective but also versatile, as it can be controlled remotely or manually and includes fail-safe features that enhance safety during power outages.

So, how does a mag lock system work in various scenarios? From managing access via keypads or biometric scanners to ensuring emergency exit capabilities, mag locks play a crucial role in maintaining security while allowing for easy access. Their reliable operation, combined with low-voltage power requirements and fail-safe mechanisms, makes them a preferred choice for securing doors in numerous settings.

How does a mag lock system work

Magnetic locking mechanisms, often referred to as mag locks, are commonly used for securing doors in various settings. Their operation is straightforward yet sophisticated, ensuring both security and ease of access.

Components of a Magnetic Lock System

Electromagnet: This component is mounted on the door frame. It consists of a coil of wire through which electric current flows to generate a magnetic field.
Armature Plate: Attached to the door itself, this metal plate interacts with the electromagnet.

How the System Operates

When electricity flows through the electromagnet, it generates a strong magnetic field. This magnetic field attracts the armature plate, creating a secure bond that holds the door firmly closed. This mechanism ensures that the door remains locked as long as the current is supplied.

Controlling Access

Access to the door can be managed through various means:

Remote Control: Power to the electromagnet can be controlled remotely. This is often done via access control systems like keypads, card readers, or biometric scanners.
Manual Control: In some cases, access might be controlled manually by toggling the power supply.

Fail-Safe Mechanism

Mag locks are designed to be fail-safe. This means that if there is a loss of power—due to an outage or intentional interruption—the magnet will release its hold. Consequently, the door can be opened easily, which is a critical safety feature in emergencies.

Are Mag Locks Fail-Safe?

Yes, mag locks are considered fail-safe. They require a continuous power supply to stay locked. If power is lost, the lock disengages, allowing the door to open. This feature is crucial for ensuring that occupants can exit quickly in case of emergencies, such as power failures.

What voltage is a mag lock?

Mag locks generally operate using low voltage. They typically require a power supply of either 12VDC or 24VDC. Different types of mag locks, including standard, slimline, mortice, and double configurations, all adhere to these voltage requirements.

Standard Maglock: Operates at 12VDC or 24VDC.
Slimline/Mini Maglock: Usually functions on 12VDC or 24VDC.
Mortice Maglock: Typically uses 12VDC or 24VDC.
Double Maglock: Requires double the power of a single maglock, so it operates on 12VDC or 24VDC in dual configurations.
Architectural Maglock: Commonly powered by 12VDC or 24VDC.
Externally Rated Maglocks: Designed for various environmental conditions, typically using 12VDC or 24VDC.
Fire-Rated Maglocks: Comply with fire safety standards and generally use 12VDC or 24VDC.
Door Retaining Magnets: Commonly operate on 12VDC or 24VDC.
Specialist Maglocks: Including high holding force or micro maglocks, usually require 12VDC or 24VDC depending on their specific design.

Why is my mag lock not working?

Several issues can cause a mag lock to malfunction:

Mechanical Issues:
- Misalignment: If the lock or door is misaligned, the armature plate may not properly interact with the electromagnet.
- Debris or Dirt: Accumulation of dust or dirt can obstruct the lock's operation.
- Warped Door: A warped door can lead to alignment problems.
- Improper Installation: Issues with the strike plate or mounting can affect functionality.
Electrical Issues:
- Power Supply: An inadequate power supply can prevent the magnet from engaging.
- Cable Issues: Damaged or insufficiently thick cables can disrupt the power flow.
- Power Outages: Lack of backup power during outages can halt the lock’s operation.
- Equipment Problems: Faults in the lock's electrical components or software can lead to failures.

Troubleshooting Steps

Inspect Cables: Check for thickness and signs of damage; replace as needed.
Examine the Door and Lock: Remove any dust or debris and look for visible damage.
Check Alignment: Ensure that the lock and door are properly aligned.
Look for Oil Residue: Oil may indicate a need to replace the closer.
Inspect and Adjust the Closer: Replace if damaged and adjust if the door slams or closes too quickly.
Install Backup Power: Consider adding a battery or generator to address frequent power outages.

By following these guidelines, you can ensure that your magnetic lock system functions efficiently and securely.

How do mag locks work

noreply@blogger.com (CouHome) — Tue, 20 Aug 2024 15:29:00 +0000

At their core, these devices consist of an electromagnet and an armature plate. When electrical current flows through the electromagnet, it creates a magnetic field that attracts the armature plate, holding the door firmly in place. This magnetic attraction provides a reliable locking mechanism that can be either fail-safe or fail-secure, depending on the needs of the installation.

Understanding how do mag locks work involves appreciating the interaction between these two components and the electromagnetic principle behind them. Maglocks offer various advantages, such as ease of installation and remote control, but they also have limitations, including their dependency on a continuous power supply. Their effectiveness is heavily reliant on the alignment of the electromagnet and armature plate, ensuring that the magnetic force is maximized for optimal security.

How Magnetic Locks Work

Magnetic locks, also known as maglocks, operate on the principles of electromagnetism. They are designed to provide a secure locking mechanism through a straightforward yet effective process.

Basic Components

At the core of a maglock system are two essential components: the electromagnet and the armature plate. The electromagnet is created when an electrical current passes through a coiled wire, or solenoid, wrapped around a metal core. When the current flows, it generates a magnetic field. The armature plate, typically made of ferromagnetic material, interacts with this field to create a strong attraction.

Functionality

When the maglock is energized, the magnetic field produced causes the electromagnet and the armature plate to attract each other forcefully. This magnetic attraction holds the door securely in place. The effectiveness of the lock depends on the alignment of the electromagnet and the armature plate; they need to be perfectly aligned to maximize holding force.

Electromagnetic Principle

The operation of a maglock is grounded in the fundamental principle that an electric current through a coil generates a magnetic field. When the coil is wrapped around a ferromagnetic core, such as soft iron, the magnetic effect is significantly intensified. The core's internal magnetic domains align, boosting the magnetic flux density and enhancing the locking force.

Types of Electric Locking Devices

Maglocks come in various types based on their functionality:

Fail-Safe Locks: These locks automatically unlock when power is lost. They are often used in emergency exits, ensuring quick access during power failures.
Fail-Secure Locks: These locks remain locked when power is lost, providing consistent security but requiring a backup power source for operation.

Pros and Cons

Maglocks offer several advantages:

Remote Control: They can be operated remotely by adjusting the power source.
Ease of Installation: With fewer interconnecting parts, installation is straightforward.
Durability: They are less prone to damage from forceful entry attempts compared to traditional locks.

However, they also have limitations:

Power Dependency: Continuous power is necessary to maintain security.
Power Outages: They can become inoperative during power failures.
Cost: Generally more expensive than mechanical locks and may require additional hardware for optimal operation.

Types of Magnetic Locks

Maglocks are categorized in various ways based on material, installation type, holding force, and functionality.

1- Material-Based Classification

Aluminum Alloy and Stainless Steel: Aluminum alloy locks offer a good balance between cost and strength, while stainless steel locks are more durable and fire-resistant.
Wire Material:
- Copper Wire: Provides excellent conductivity but is expensive.
- Copper-Clad Aluminum Wire: Balances cost and performance.
- Aluminum Wire: The most cost-effective option but has higher power consumption and potential overheating issues.

2- Installation-Based Classification

Surface Electromagnetic Locks: These are mounted directly on the wall or doorframe, making them easier and quicker to install but more exposed to tampering.
Hidden Magnetic Locks: Embedded within the wall or door frame, these provide better tampering protection and water resistance but involve more invasive installation.

3- Holding Force-Based Classification

Single-Door Locks: Varying from 130 lbs to 1200 lbs, catering to different security needs.
Double-Door Locks: Withholding forces ranging from 700 lbs to 2400 lbs, suitable for double-leaf doors requiring enhanced security.

4- Functionality-Based Classification

Signal-Output Magnetic Locks: Equipped with sensors like DSS (Door Status Sensor) or LSS (Lock Status Sensor) for feedback to access control systems.
Time Delay Electromagnetic Locks: Feature adjustable delays for locking after unlocking.
Beep Buzzer Magnetic Locks: Include an audible alert for added security.
Waterproof Magnetic Locks: Designed for outdoor use, these locks are sealed to meet waterproof standards (e.g., IP68).

Can Magnetic Locks Operate Without Electricity?

Magnetic locks are inherently fail-safe devices. This means they require a constant power supply to remain locked. When the power is lost, the magnetic field that holds the lock in place is de-energized, causing the lock to release automatically. This characteristic makes maglocks suitable for emergency exits, where quick egress during a power failure is crucial. However, this also means that their security is compromised during power outages, as they can unlock automatically, potentially exposing them to tampering.

How to find the right door latch: A Step-by-Step Guide

noreply@blogger.com (CouHome) — Mon, 19 Aug 2024 20:19:00 +0000

From mortise locks to screw-on locks: When choosing, you must pay attention to the dimensions of the bolt, strike plate, latch case, lock cylinder and locking mechanism. Whether DIN left or DIN right, the opening direction of the door must also be taken into account. Here you can find out everything you need to know about mortise latches, security locks and more!

Choosing a door latch: important criteria

This makes replacing your door latch child's play:

Remove the old model.
Take a tape measure, a piece of paper and a pencil. Measure everything and write down the measurements.
Pay attention to the opening direction of the door, compare the locks and choose the right one!

Replacing the door latch: You need to pay attention to these features

If you are not an expert, you can determine the features that your new door lock must have based on the following criteria:

Mortise lock or screw-on lock;
vertical or horizontal;
DIN right or DIN left;
Dimensions of the lock case, the faceplate, the bolts, the lock nut and the distances.

Locking mechanism

Locking can be achieved using various mechanisms:

Locking cylinder: Locking via a cylinder that is operated with a key.
Beard lock: Locking via an integrated mechanism in the lock case with a bearded key.

The right lock cylinder

Locking cylinders are usually the same size

The security level depends on the model: protection against mechanical break-in attempts, drilling protection, security card, etc. Look for the VdS quality seal. Locking cylinders are available in different versions:

A locking cylinder with emergency and danger functions can be opened from the outside if a key is inserted from the inside;
Half cylinder, can only be closed from one side,
The knob cylinder is operated with a key on one side and a knob on the other.

You can find out more about the meaning of all these terms in the next section!

Technical terms for door latch: a small locksmith lexicon

To understand how a door lock works, it is important to know the correct terms for its individual elements and functions.

Door lock: definitions

Door lock: Locking system that can be operated with a door handle, key or knob. Door locks are used to close and lock doors - door handle + key.
Closing: A door is closed with a handle, which in turn operates a lock.
Locking: Not to be confused with closing a door. Doors can be locked using key-operated locks.
Locking cylinder: It is also known as a profile cylinder. It has a cylinder core with a cylindrical shape and represents the security element of the lock.
Deadbolt lock: Lock with manual locking from the inside using a knob and from the outside using a key.
Lock case: External part of a lock that contains the entire locking mechanism. It can be mounted or installed.
Latch or latch: solid, movable part that locks a door when locked in the strike plate. Latches and deadbolts are the parts of the lock that are moved in and out using keys or door handles. Some traps can be reversed and are therefore suitable for left and right opening doors.
Locking lug (locking cam): Latch of the cylinder that enables locking.
Lock nut: a rectangular, cuboid piece of metal that connects the handles to each other, is guided through the lock and activates the latch and bolt. It is available in different sizes. 8 mm is common for room doors and 10 mm for front doors.
Door handle: often in the shape of a latch, allows the latch to be released from the striking plate and thus opens the door.
Strike plate: Metal element on the door frame, forms the housing into which the latch and bolt slide for closing or locking.
Pull handle: replaces a handle on the inside of a lock. Handle that you pull to release the latch from the strike plate.
Forend: an attached part in a mortise lock that allows the lock case or striking plate to be attached. Its ends can be round or square.

Determine the opening direction of a door

Door opening to the right

Your door opens to the right (DIN-right) if you stand in front of the hinge side and the hinges are on the right.

The door opening to the left

Your door opens to the left (DIN left) if you stand in front of the hinge side and the hinges are on the left.

To tell whether a door is DIN right or DIN left, remember the following sentence: “DIN is where the hinges are visible”.

Door Latch Types: Overview

For the sake of simplicity, we differentiate between two types of locks:

Mortise locks or built-in locks;
Screw-on locks.

Mortise lock: detailed view and function

A mortise lock sits in the door leaf. This must therefore be wide enough to accommodate the lock case of the door lock. Latches and latches enable a door to be closed and locked. The latch is usually reversible so that it can be used in both opening directions.

Screw-on lock: detailed view and function

A screw-on lock is attached to the door leaf instead of in the door leaf. It is suitable for thin doors, metal doors and for anyone who does not want to chisel out their wooden doors. These screw-on locks allow for closing and locking. Here too the trap can be reversible.

Select mortise lock

Take measurements for a mortise lock

Since the lock is located in the door, you have to pay close attention to the dimensions when making your selection. When replacing such a lock, you must consider the following points:

Height and depth of the lock case;
Distance between the lock nut and lock (cylinder lock or warded lock);
Dimensions of the latch and deadbolt so that they fit into the strike plate;
distance between latch and latch;
Distance between the faceplate and lock nut/lock cylinder.
Dimensions and shape of the cuff end (width and height, square or round).

In short, your new mortise lock must have the same properties as the old lock if you do not want to carry out any modifications to your door. If the lock nut is smaller, you will need a reducer to operate a 6mm lock nut with a 7mm square pin.

How to find the right screw-on lock

Take measurements for a screw-on lock

Its design makes choosing a screw-on lock easier. To ensure that the exchange goes smoothly, you should pay attention to the following:

Diameter of the cylinder for cylinder locks;
size of the lock box (for painted doors, a large box is better than a small one);
Distance between lock nut and lock (cylinder lock or warded lock with matching key);
Size and shape of the cuff (width and height, square or round).
Distance between the faceplate and lock nut/lock cylinder.
Height and depth of the lock case.
The size of the latch and deadbolt does not matter as the striking plate is mounted face-to-face (delivered with the lock).

Difference between single and multiple locking

The difference between these two systems lies in the number of locking points, i.e. the number of latches.

A single lock can be built into the door or attached to the door. It only has one latch, i.e. one point to lock the door.
A multi-point lock can also be screwed onto the door or inserted into the door. It has several locks: The door is locked with several bolts. Most multi-point locks have three to four latches. This type of locking is usually supplemented with an espagnolette lock on the top of the door.

Espagnolette locks under the microscope

An espagnolette lock consists of one

Cylinder latch and warded latch: differences

Door latches have different locking mechanisms.

Cylinder lock

To buy a new lock, you need to know its shape, length, security level and number of keyholes. The key is usually flat and has one or two profiles with cuts or punches.

Buntbeard Castle

The lock is integrated into this lock. The key is usually quite heavy. It is called a Buntbeard key or, if it has millings, a Chubb key. This type of lock is suitable for indoor use.

These locks can be constructed horizontally or vertically, depending on the format of the lock case. If they are taller than they are wide, they are said to be vertical. If they are wider than they are tall, they are said to be horizontal.

There are also electric locks. These are door locks that can be opened with a card, badge or via a key code (from the inside). Some locks can even be opened remotely.

Now what? Cylinder, lock, bolt?

noreply@blogger.com (CouHome) — Sat, 11 May 2024 15:26:00 +0000

Anyone who doesn't deal with locking systems very often will quickly notice when talking to experts that they don't have the right terms. This leads to misunderstandings because the term “lock” is used but “cylinder” is meant. To prevent this from happening, we have compiled and explained the most important terms in this glossary.

Many of the definitions are clear and difficult to interpret. But things are different with modern names such as “access control system” or “locking system”. Whether a door can only be opened with a key or with a chip card is not determined per se by the two terms mentioned.

In order to be able to make a clear distinction between the terms, CouHome only uses the word “locking system” when it comes to systems with keys. If doors are to be opened using a chip card, Bluetooth or code lock, we call them access control systems. The clear distinction is helpful because locking systems do not require a power supply to the door, but access control systems require a power supply.

glossary

Scanning security – This indicates how difficult it is to obtain the information using suitable technical tools in order to create a duplicate key. It can be increased using recesses in several dimensions or embedded magnets.

Hinge Side – The side of a door where the hinges are normally visible.

Backset – The backset is the distance between the front edge of the lock (→ forend) and the centre of the → lock cylinder. It is important because the forend screw must be at least as long as the backset in order to lock the cylinder in the lock.

Double cylinder - It is a special type of → locking cylinder that can be operated from both sides with a key. A distinction is made between standard cylinders and those with → comfort functions.

Mortise lock - lock with latch and bolt according to DIN 18 251 for installation in various doors. Mortise locks can have a cam lock, tumbler or profile cylinder locking mechanism or can be mortice locks with a bathroom bolt. The most important components of a mortise lock are → latch, → faceplate, → bolt, change, follower, → lock case and tumblers.

Latch (or lock latch) - Part of the lock that protrudes from the lock when the door is open and is pushed into the lock by pressure on an inclined surface when the door is pushed shut or "slammed shut". If the door is completely closed, a spring presses the latch into the recess in the striking plate and thus keeps the door closed. This often happens with a clearly audible “click”. The latch can be pulled back using the door handle or with a key to open the door.

Same locking - If two cylinders have the same → locking (i.e. can be locked with the same key), this is called simultaneous locking. This makes sense if the garage and front door can be locked with the same key or if several rooms in a company should be able to be accessed by a specific group of people.

Convenience function - In unfortunate situations, it may be necessary to operate a lock from the outside even if a key is inside and may be twisted. Cylinders with a convenience function technically offer the possibility of being able to operate the lock independently of a key that may be inserted on the other side.

Knob – A usually immovable round handle on one side of the door so that it can be opened with a key after unlocking.

mechatronic – a portmanteau of mechanical and electronic that describes a technology in which mechanical and electronic components work together. In mechatronic → cylinders, for example, the electronics ensure that if the electronic registration is successful, the key is turned mechanically and the → bolt can be moved.

Multi-point locking – A locking device that secures a door at several points (points) using → latches, bars or bolts. It increases security because it makes it more difficult for attackers to break down the door.

Re-locking security - Describes the degree to which it is difficult to operate a locking cylinder with a key other than the associated key. Re-locking security can be achieved through a special shape of the key profile as well as through appropriate key profile controls, such as side control pins, balls or tilting elements. All measures to minimize wear in the locking cylinder and on the key also ensure a high level of relocking security.

Reide (key reide) – head or handle of the key.

Deadbolt - A metal rod in the lock that is moved when a key is turned in the cylinder to lock or unlock the door. There is a recess in the → striking plate of the door frame for this). Security doors can also have multiple bolts.

Locking system – a complete system consisting of cylinders, keys and (for electronic and mechatronic systems) hardware and software for programming and managing keys and cylinders. If systems with electronic locking cards are also referred to, they are often referred to as access control systems.

Locking - This refers to the configuration of the key and cylinder, which determines how the key must be designed so that it can be turned into the cylinder. If there are several cylinders for several keys that can be locked with these keys, this is referred to as → keying in common.

Locking system – The way the lock technology works. A distinction is made between mechanical and mechatronic.

Key bit – The part of the key that is inserted into the → lock cylinder and is “checked” by the cylinder to clear the cylinder core for rotation.

Strike plate – Mechanical, often metal, stable device in the door frame (frame) with recesses for the latch and bolt of the lock. It prevents the door from opening if the latch and/or bolt protrude into the recesses. As a security striking plate, it is connected to the masonry behind the frame using wall anchors. An electrical strike plate contact (bolt switch contact) can also be installed on the strike plate.

Lock cylinder – see → Cylinder

Lock – Mechanical, often metal unit that is built into the front of the door leaf. It usually consists of the → lock case, → faceplate, → latch and → bolt and recess for the → lock cylinder. Modern locks can also be operated electrically. The lock does not include → door handle and → cylinder. The lock secures the door from unauthorized opening.

Lock case – is the visible shell of a → lock when it is removed.

Key channel – opening and guidance within the → locking cylinder into which the key can be inserted.

Key Security – The difficulty of keys being copied without authorization and for unfair purposes. Key security is determined by the type of key (technical copy protection) and the availability of raw keys (free key profiles and patented (= protected) key profiles).

Security fitting - A door handle set consisting of the following parts: outer plate, inner plate, connecting element between outer and inner plate, door handle on the inner plate, any door handle or fixed knob or push handle (handle plate) on the outer plate, if necessary with an additional cover for the locking cylinder.

Security card – identification in credit card format that is issued for a → locking system or an individual → locking cylinder and only entitles the owner to obtain replacement keys and/or locking cylinders for the relevant → locking system or locking system.

Forend - front plate for mortise locks for carrying the → bolt and → latch out of the → lock case and for fastening the mortise lock in the door leaf with one or more fastening screws above and below the lock case.

Door hinge – metal hinge on the hinge side of a door, both in the door leaf and → door frame. Often with interlocking metal pins to prevent the door from being levered out. Door hinges with springs are able to close doors automatically.

Door handle - a handle on one or both sides of the door that, when pressed, pulls the → latch and thus allows the door to be opened. Alternative names are handle, buckle, and pusher.

Reversible key – a key that does not matter in which orientation it is inserted into the key channel. It has identical troughs and safety features on both sides of the beard.

Frame – frame in the masonry in which the door is hung via hinges and which accommodates the striking plate as a counterpart to the lock.

Access control – A system that ensures that only authorized people have access to certain areas and facilities. This can be ensured via locking systems or access control systems.

Access control systems - systems and products to protect against unauthorized access to sensitive areas such as offices, data centres, laboratories, cash registers, archives, production facilities, vaults, etc. In contrast to locking systems that use keys, access control systems also use chip cards and fully electronic authentication means, to check access authorizations. Readers must be installed for authentication.

Cylinder cover – Additional cover on the protective fitting to prevent the → locking cylinder or its core from being pulled out forcibly.

Cylinder or locking cylinder - Interchangeable part of a lock that uses suitable technology to check whether the key can be turned and thus the bolt or latch moved after inserting a key. In the case of mechanical cylinders, the test is often carried out using pins that have to be pressed in correctly through the key bit in order to be able to turn the lock cylinder core. The cylinder is locked in the → lock by a forend screw and can therefore only be changed when the door is open.

Door Lock types: What different types of cylinders are there?

noreply@blogger.com (CouHome) — Wed, 08 May 2024 20:36:00 +0000

There are a whole range of different types of cylinders. The most common are the double cylinder, the knob cylinder and the half cylinder. But there are many other types of cylinders, which we describe below.

Double cylinder

The double cylinder is the classic locking cylinder for front doors. With this type of profile cylinder, the lock can be locked from both sides with a matching key.

With a standard double cylinder, the door can no longer be unlocked if a key is already inserted from the other side. To ensure that this is still possible, the double cylinder must be equipped with an emergency and hazard function.

To increase the security of such a locking cylinder, core pull protection or drilling protection is recommended.

Knob cylinder

A knob cylinder is also often used on entrance doors. It differs from a double cylinder in that it can be operated with a key on one side and a knob on the other side.

The knob cylinder is always a good choice when protection against burglars is only required on one side of the door. It is less suitable for doors with windows. Burglars could then break the window and gain access to your home via the knob. If there are small children in the house, a knob cylinder can also be suboptimal because children may be able to turn a knob quite early.

Half cylinder

A half-cylinder is a type of cylinder that can only be locked from one side. This means that a half cylinder can do exactly half of what a double cylinder can do. Classic areas of application include garage doors, key boxes, alarm systems and much more. In other words, everything that only needs to be locked from one side.

Short cylinder

Strictly speaking, a short cylinder is not a separate type of cylinder, as it can be used as a double, knob or half cylinder. The special feature of a short cylinder, however, is that the short side is fixed at 27 mm. The long side can be freely configured from a length of 35 mm. The short length of the cylinder means that the security of this type of cylinder is somewhat reduced. For this reason, a short cylinder is primarily used for garden gates and thin entrance doors.

Lever cylinder

The lever cylinder is also one of the cylinder types. This locking cylinder can be opened and closed from one side with a key. On the other side, there is a lever that determines the locking state of the lock. When the lock is closed, the lever blocks the opening from the inside. If you now unlock the lock from the outside with a suitable key, the lever moves to the neutral position and the door/hatch can be opened.

The best example of the use of this type of locking cylinder is a mailbox.

Padlock / Padlock

The padlock is not permanently installed and is instead simply hooked into the eyelets provided. A padlock can be used to lock doors that do not have a door lock or that you want to secure additionally.

Classic areas of use for padlocks are garden arbours, garden sheds or garden gates.

Outer cylinder

The external cylinder gets its name because it is attached from the outside. In the case of the box or additional locks that are installed inside, it is attached from the outside and connected to the locks with a metal tongue.

Blind cylinder

Blind cylinders are designed for all doors that do not need to be locked. The blind cylinder simply blocks the door lock and prevents smoke or toxic fumes from passing through the opening of the door lock in the event of a fire or other incident. The blind cylinder is used primarily for passage doors.

Cylinder Types: How do I determine the length of a cylinder?

To determine the length of a cylinder, you can either remove it and then measure it, or you can measure it when it is installed. It is usually easier if you measure the locking cylinder when it is installed.

To do this, you have to open the door and need a folding rule to measure. You need two measurements: the inside and the outside. Now measure from the faceplate screw to the inside of the door to the point where the profile cylinder ends. This will determine the inside measurement. For the outside measurement, measure from the faceplate screw to the end of the profile cylinder on the outside.

Which locking cylinder for the front doors?

Double cylinders and knob cylinders are ideal for front doors. The double cylinder is a good choice for almost every front door. The knob cylinder should only be used if the door does not have an excessive amount of glass.

how to change door lock: step-by-step instructions

noreply@blogger.com (CouHome) — Mon, 06 May 2024 20:20:00 +0000

If you've ever had the experience of being locked out, you'll know how frustrating it can be. Even more so if you don't have a spare key or the keys have been lost or stolen. Even if your lock cylinder is getting old, it may be worth changing. But don't worry - replacing your lock cylinder isn't difficult and doesn't require any special locksmith skills.

In this blog post, we'll go through each step in detail so you know exactly what to do when replacing an old lock on any door with a new one.

Whether you want to regain access to your home or take additional security precautions, these steps will make it a breeze!

What dimensions does my new locking cylinder need?

Not all cylinder locks are the same, as they come in different sizes. To ensure you get a new locking cylinder that fits your door perfectly, you should first measure the old cylinder or the door fittings.

For this, you will need a ruler or folding rule, a screwdriver and a square or Allen key.

Now measure the distance from the centre of the adjusting screw, which is located under the door latch, in both directions to the end of the door fitting. With the inner and outer lengths, you now have the values you need to buy a new locking cylinder.

The easiest way is to remove your old locking cylinder and simply take it with you when you get a new one.

How do you replace a locking cylinder?

It is not that difficult to replace a locking cylinder. With good instructions, you can easily remove the locking cylinder and change the door lock yourself.

Step 1: Loosen the forend screw

On doors, there is a screw under the door latch that you must first remove in order to be able to take out the old locking cylinder. This so-called faceplate screw holds the cylinder lock in place.

Step 2: Remove the old locking cylinder

Once the forend screw is loosened, you can easily remove the cylinder. To do this, turn the key in the lock a little and simply pull out the cylinder lock.

If the locking cylinder is stuck and cannot be removed, you can tug on it a little or loosen the screws on the door fittings a little. If that doesn't help, you should remove the door fittings completely. But this is usually not necessary.

Step 3: Insert the new locking cylinder

Insert the new cylinder in the same way that you removed the lock cylinder in the previous step. Make sure that the locking lug does not block the insertion of the lock cylinder.

Step 4: Tighten the forend screw

If the new locking cylinder is correctly seated in the socket, you must fix it again with the adjusting screw. It is best to use the new screw that comes with your new cylinder, even if the old screw should also fit.

If you have completely removed the fittings from your door, you will of course have to reattach them before fully tightening the faceplate screw.

Step 5: Test the locking process

Once the new door lock is installed, all you have to do is check that it is firmly in place and working properly. Give it a little shake and test opening and closing the door.

If everything worked without problems, you are done and have successfully replaced your locking cylinder.

Remove the locking cylinder without the key

If, for whatever reason, you no longer have a key but still want to remove the locking cylinder, there is a solution for this too.

If the door on which you want to remove the door lock is closed, you can drill the lock open. Take a hard drill and drill below the keyway until it is about halfway into the lock. You should now be able to open the lock with a screwdriver. But be careful: with locks with anti-drill protection, drilling is obviously not possible.

If you want to remove the lock from a door that is already open but doesn't have a key, you can use a sturdy pair of pliers instead. After you have removed the fittings and screws on both sides of the door, press the pliers firmly against the narrow side of the cylinder and tug on it until it breaks. You can then remove the pieces of the locking cylinder from the door.

Changing the locking cylinder - FAQ

Can you change a door lock yourself?

Even if you don't have any special knowledge, you can easily replace a door lock yourself with good instructions. Just follow the steps and you will have replaced your locking cylinder in no time.

How much does a new locking cylinder cost?

Depending on the security level, door locks cost different amounts.

How much does it cost to replace a locking cylinder?

If you don't want to change the cylinder lock yourself and get a locksmith to help you, just changing the cylinder usually costs between 50 and 100 Dollars. Losing a key can be particularly expensive: If you no longer have a key, this drives up the costs significantly.

Can you replace a lock yourself?

Yes, you can replace locks like mortise locks yourself, even without much experience. You usually don't need more than a few tools and a good step-by-step guide.

Does it matter which way a locking cylinder is installed?

In principle, the locking cylinder can be installed in both directions, but should ultimately be flush with the door leaf, i.e. not protrude, for example. However, since door leaves are usually constructed asymmetrically and the cylinder therefore has sides of different lengths, it is difficult to install it the wrong way round without being noticed.

WHAT IS A PROFILE CYLINDER LOCK? PROFILE CYLINDER LOCK EXPLAINED EASILY!

noreply@blogger.com (CouHome) — Sun, 05 May 2024 13:16:00 +0000

The profile cylinder lock is a lock which, together with the so-called profile cylinder / locking cylinder, ensures that a door can be locked and unlocked again with a key.

The key needs the right profile (the right teeth) so that the pins in the locking cylinder do not block the rotation of the key. If the key does not have the right teeth, the pins block the attempt to unlock it, so that the profile cylinder lock enables very effective access control. This is an important reason why the profile cylinder lock has become so popular in Germany and can be seen as the standard lock.

All components of the profile cylinder lock must be precisely matched to the design of the house or apartment door so that the door can be securely locked and quickly unlocked again.

PROFILE CYLINDER LOCK AS MORTISE LOCK OR WITH LOCKBOX

The profile cylinder lock is usually a so-called mortise lock that is inserted into a cavity inside the house or apartment door. This cavity inside the door is also called a lock pocket. As an alternative to the lock pocket, there are also locks with a lock case. These are attached to the door from the inside (or more precisely: to the door leaf).

A conventional profile cylinder lock generally consists of a latch (also known colloquially as a snapper) and a bolt. Special locks have several bolts. This is then referred to as multiple locking.

When the door is closed or locked, the latch and bolt move into the holes provided for them in the strike plate.

The profile cylinder lock and the profile cylinder are protected by the door fittings against violent attacks (in the event of a break-in attempt). In this context, it is important to mention that there are a wide variety of fittings and protective fittings made from a wide variety of materials, such as aluminium, steel, stainless steel or brass. Particularly high-quality and secure door fittings feature core pulling protection and drilling protection.

HOW A PROFILE CYLINDER LOCK WORKS

The lock itself usually works with a bolt that can be extended and retracted and thus closes and opens the corresponding door, as well as a so-called latch. The latch itself ensures that a closed door does not open again on its own.

The door latch is connected to the door handle and is retracted as soon as the door handle is pressed or turned, depending on the variant. Since the door handle can normally be operated without a key, the latch cannot be considered to have any significant security aspect.

The situation is different with the bolt, which is used to lock the lock. This can usually only be operated using a key. When the cylinder lock is turned with the key, the bolt is pushed out of the lock and into the hinge attached to the door, or in the opposite direction. There are also higher-quality door models that not only work with a bolt but also have additional locking elements on the top and bottom of the door.

PROFILE CYLINDERS ARE EASY TO REPLACE

The advantage of a cylinder lock is that the cylinder can be changed quite easily by skilled locksmiths. Dismantling is easy and, depending on the cylinder, it is even possible to change the locking code manually without purchasing a new profile cylinder lock. To do this, the pins that are fitted in the cylinder are replaced with the desired size.

Everything you need to know about mortise locks: types, installation and dimensions

noreply@blogger.com (CouHome) — Thu, 02 May 2024 20:30:00 +0000

In this article, you will learn what types of mortise locks there are and what areas of application they are suitable for. You will also learn everything you need to know about the structure and function of mortise locks, the most important dimensions so that you can determine the right mortise lock for your door and other important tips.

1. Basics

Mortise locks are the most common form of door lock today. You can find them in every apartment and room door.

They are inserted into a rectangular recess that is milled into the door leaf. Mortise locks are only visible on the front edge (also called the closing edge) of the door leaf when the door is open.

In contrast, there are screw-on or box locks that are mounted on the outside of the door leaf and are therefore also visible when the door is closed. Image of mortise lock vs. screw-on lock

Mortise locks are available in different sizes and designs. They can be used on both interior and exterior doors. Important points when choosing the right mortise lock are:

the right dimensions
the right type
the right safety class

We will discuss these points in more detail below.

2. Structure of a mortise lock

Let's first take a quick look at the structure of a classic mortise lock so that you become familiar with the technical terms. The further information in this article builds on this.

A mortise lock usually consists of the following parts:

Faceplate: Open a door and look at the narrow side of the door leaf from the front. There you will see the so-called faceplate. This is the name given to the sheet metal that remains visible from the mortise lock when it has been installed in the door. In the faceplate, you will usually find a drill hole at the top and bottom. The mortise lock is fixed to the door leaf via these. The latch and the bolt also protrude from the faceplate.
Latch: This is used to lock the door. It snaps into place when the door is closed and prevents the door from opening accidentally. The latch can be released, for example, by operating the door handle so that the door can be opened. The latch only closes the door but does not lock it.
Deadbolt: If you look at the faceplate from the front, the lock deadbolt is usually located below the latch. It is usually operated with a key. If you lock a door with a key, the deadbolt is pushed out of the mortise lock and into the strike plate. The door is now locked. If you unlock the door again with the key, the deadbolt is essentially retracted and the door is unlocked.
Strike plate: This is the counterpart to the mortise lock. While the mortise lock is set into the door leaf, the strike plate is set into the frame (colloquially also often referred to as the door frame). It accommodates both the latch and the bolt via two openings and thus enables the door to be closed and locked.
Handle nut: Refers to the round opening in the mortise lock which accommodates the square of the door handle. The square is a metal pin with a square cross-section which is pushed into the handle nut. For interior doors, a door handle is usually pushed onto the square from both sides of the door leaf. For exterior doors, however, a fixed doorknob is often used on the outside of the door leaf. The nut spring ensures that a door handle moves back up after being operated, thus extending the latch out of the door leaf.
Lock base and lock cover: These metal sheets together form the so-called box of the mortise lock. It is located behind the faceplate and is no longer visible once the mortise lock has been recessed into the door leaf.

3. The most important dimensions

To ensure that you are really happy with your newly purchased mortise lock, you should make sure that you buy the right size. Mortise locks are standardized, but there are different sizes. You need to know what size you need for your door so that the lock fits.

Mortise depth: The mortise depth refers to the distance from the front edge of the mortise pocket (in the door leaf) to the deepest point of the pocket that accommodates the mortise lock. The mortise depth is usually measured in millimetres. Understandably, the mortise lock box must not be larger than the mortise pocket in the door leaf.

Backset: The distance between the centre of the keyhole (and the square pin) and the outside of the faceplate is called the backset. If you want to replace your existing mortise lock, the backset is particularly important. Only with the correct backset can you ensure that the door lock (e.g. profile cylinder or warded lock) and square are in the designated places and are thus congruent with the recesses provided for them in the door leaf.

Distance: If you already have door fittings and are looking for the right mortise lock, or conversely need the right door fittings, the distance is an important factor. It describes the distance between the centre of the square and the centre of the locking cylinder. For front doors or doors that use a profile cylinder, this distance is usually 72 or 92 mm in Germany, and usually 88 mm in Austria. For interior doors with a deadbolt lock, the distance is usually 72 mm in Germany and 90 mm in Austria.

4. What types of mortise locks are there?

Mortise locks are usually available in the following variants:

With profile cylinder hole (PZ hole): This variant is suitable for external or front doors, as a profile cylinder can be installed in it. In contrast to the warded lock, this offers significantly more security against burglary.

Profile cylinders are usually also equipped with a so-called change function. What does that mean? You open a traditional room door by pushing the door handle down. However, this is not possible with a front door with a fixed knob on the outside. In order to be able to open this without a door handle, there is the so-called change. This allows you to release the latch with one final turn of the key and thus open the door.

With warded hole: This variant is suitable for interior doors that can only be locked with a warded key. Warded keys are the classic room door keys.

These types of locks are very insecure and therefore not suitable for external doors. They can be picked, i.e. opened, relatively easily, for example with a lock pick. However, this can actually be an advantage for interior doors, for example, if a small child has locked themselves in.

With bathroom latch: With this variant, the door is not locked with a key, but with a rotary knob on the inside of the door (or the door leaf). For safety reasons, however, there is a device on the outside that allows the door to be opened from the outside in an emergency using a hexagon key or pliers.

5. What else do you need to pay attention to when choosing the right mortise lock?

Another important factor is the direction in which the door opens, i.e. the door stops. You can find out how to tell which stop your door has in our detailed door guide in the section “How to determine the door stop correctly”.

In summary, there are two standardized types of stops:

Doorstop DIN right
Door stop DIN left

Make sure that your mortise lock is designed for the correct door stop. Many mortise locks today have a rotating latch and can therefore be used on both sides, i.e. for both types of stop.

Also important are the different security classes, which differ significantly in their protective functions. We will discuss these in more detail in another article shortly.

We hope that this little guide has helped you to make a decision when buying your next mortise lock. Do you have any questions or would you like to add something? Please let us know in the comments!

How to find the right locking cylinder

noreply@blogger.com (CouHome) — Wed, 01 May 2024 11:55:00 +0000

Profile cylinders are among the best-known and most frequently used locking cylinders. Whether flat key or reversible key, emergency function, knob cylinder or double cylinder: here you can find out more about locking cylinders and their properties.

Lock cylinder: Overview

The most common locking cylinder in the United States is the profile cylinder.

Profile double cylinder: the classic

The double cylinder is one of the most common profile cylinders. It has 6 pins and protection against drilling and breaking. It has a nickel coating and is usually supplied with 5 keys. These are either flat or reversible keys.

Cylinder lock: structure

Cylinder locks can be made of different materials, have different lengths and, above all, work with different types of keys and mechanisms, which are often manufacturer-specific. These include:

classic profile cylinders,
cylinders with emergency and danger functions,
knob cylinders,
half cylinders.

Standards and burglary protection

A cylinder lock can have several security systems that protect your lock against burglary. These include picking protection, drilling protection, break-in protection and copy protection. Other types of cylinders are now hardly used in Germany, e.g. round cylinders.

Norms and standards

In Europe, locking cylinders must comply with the DIN EN 1303 standard in order to be considered secure against locking and break-in. There is also the Europe-wide SKG standard, which divides locking cylinders into two classes.

Determine the length of a cylinder

If you want to replace your lock cylinder, the most important feature is its length (in mm). The cylinder consists of a keyhole on each side and a locking lug in the middle, which - operated by the key - carries out the locking. To determine the length, the distance from the centre of this locking lug (cylinder centre) to the keyhole must be determined. The vast majority of cylinders measure 60 mm (total length). The total length is often given in the description as 30/30 because each side measures 30 mm from the centre of the locking lug to the keyhole. However, several variants are possible:

30/30
30/40
40/40
40/50
etc.

The reference points are always the cylinder centre and the keyhole. This criterion is crucial for replacing your locking cylinder.

When there is no key in the cylinder, the locking lug is usually at 7 o'clock (clock face) when viewed from the front. In rare cases, it can be at 3, 9 or 12 o'clock. Some cylinders have an adjustable locking lug.

Keys and locking cylinders: structure and security

Depending on the type of cylinder, the key may have notches, dimples, bumps or depressions. The profile of your key may be cross-shaped or star-shaped, but is usually flat, and milled on one or two sides. The combination of profile and notches or depressions determines the "code" needed to operate the pins inside the cylinder and block the locking lug. The right profile allows the key to be inserted into the cylinder - the right notches can turn and lock it! The more pins the profile cylinder has, the harder it is to tamper with. Expect 5 to 36 pins for a cylinder.

Key species

The right keys can increase the complexity of the cylinder when it is replaced, thereby increasing the security of the lock. The key is therefore an indication of the complexity of the cylinder:

A flat or notched key with millings on one side of the shaft is the standard. It is found on almost every bunch of keys.
A flat or notched key with millings on both sides offers a little more security because it indicates a cylinder with more pins.
A paracentric key is similar to a flat key. However, it has a key profile that overlaps the centre to offer better protection against break-ins.
A reversible key has dimples instead of notches. It fits into the lock cylinder on both sides.
Some manufacturers offer special security keys.

Have keys copied

The number of keys sold with the locking cylinder varies - often 3 to 5 keys are included. Depending on the type, the key can be copied more or less easily. Flat keys can be duplicated at any locksmith. For paracentric keys and reversible keys, you usually have to contact the manufacturer directly.

Copy-protected keys and warranty

Some keys are copy-protected or require a card supplied with the cylinder to copy the keys. Attention, keys with a lifetime guarantee can only be copied at the factory: remember the delivery times!

Complexity of the locking system = security of a cylinder?

Depending on the type of security lock, it is more or less easy to break open a cylinder lock.

It is also possible to drill through a cylinder to destroy the pins or to break it open with a hammer from the outside.

A protective fitting can help here. It prevents the cylinder from being drilled open. Breaking open is made even more difficult if the locking cylinder is made of a durable alloy that can withstand blows. Under no circumstances should the cylinder protrude from the door. It must sit flush to prevent it from being pulled from the outside.

Burglar protection for cylinder locks

A cylinder should be protected against the following burglary techniques:

Pulling - using pliers. This is prevented by flush installation.
Breaking - using hammer blows. This is prevented by a durable alloy.
Drilling - using a drill. This is prevented by a protective fitting.
Lock picking - using special tools. The more pins a cylinder has, the harder it is to crack.
Key copying. A security card prevents duplication.
Bumping - using a bump key. This is prevented by reinforcements and a protective fitting.

The SKG test mark under the magnifying glass

The SKG test mark is a Europe-wide standard that says something about the security of a cylinder lock.

Lock cylinder	Characteristics
SKG**	Cylinder with drilling and pulling protection from both sides
SKG***	Drilling protection, impact protection and core pulling protection

Locking cylinder types: half cylinder, freewheel cylinder, knob cylinder, etc.

Double cylinder

The keys can be inserted on both sides. However, locking or unlocking is only possible with one of the two keys.

Half cylinder

These cylinders are especially suitable for garage doors. They only have one key entry. Their dimensions are 30/10 mm.

Cylinder with hazard function

This function has different names depending on the manufacturer. With this type of cylinder lock, a key inserted on one side does not prevent the door from being unlocked or locked from the other side. This system is particularly practical when several people live in one household. With classic profile cylinders, the door cannot be unlocked from one side if a key is inserted on the other side.

Knob cylinder

This locking cylinder can be opened from the inside with a knob.

Locking cylinders for French doors

When buying small locks for windows and doors, you should be careful: the locking nose of these cylinders is smaller. If you can't find the model you want, file the locking nose so that it doesn't get stuck in the lock!

Locking mechanisms of a cylinder

Locking cylinder with pins

Lock cylinders with pins are the most common. The more pins there are, the more security there is. The majority of cylinders have 6 pins.

A cylinder with anti-picking protection is ideal. Pins made of nickel silver (a durable alloy) are the most secure. Depending on the arrangement of the pins, it can be difficult to duplicate the key.

Locking cylinder with rotating discs

This mechanism prevents the lock from being drilled open. This makes breaking in using a drill almost impossible.

Locking cylinder with discs

In everyday life, there is no reason to equip your door with such a mechanism. This is a high-security lock.

Bramah Castle

Such a lock is rarely used for front doors these days.

One key for several locking cylinders – is that possible?

For this, you need so-called keyed-like cylinders. These profile cylinders can all be opened with the same key, which makes your key ring lighter! The locking cylinders can be of different types.

Profile cylinder: Conclusion

Replacing a cylinder is quite simple. It is only held in place by a screw that is accessible from the edge of the door where the lock is located. Unscrew this after removing the locking lug and then simply pull the cylinder out.

A cylinder lock only protects doors that are sturdy. There is no need to buy a high-security lock if your door is made of cardboard and can be easily pushed in. The strike plate, under which the locking lug is located, is also an important security aspect. It must be firmly and properly attached.

To choose the right cylinder lock, you should pay attention to the following:

the currently installed model you want to replace;
its size;
its type;
various protection measures; t
he type of key.

And feel free to use lubricant if your lock is stuck!

The multi-point lock: what is it?

noreply@blogger.com (CouHome) — Sun, 28 Apr 2024 10:28:00 +0000

Multiple locks are those in which several deadbolts attached to the edge of a front door can be closed and opened when the key is turned. They are considered carpentry equipment that provides excellent protection against attempted break-ins. Also called a “high-security lock” or “defence lock,” this carpentry equipment has at least 3 locking points. However, it is possible to find multi-point locking models that offer 5, 7 or 9 locking points. What information do I need to know about this safety equipment?

What are the different elements of a multi-point lock?

The multiple lock is the one that guarantees optimal protection for your home. Its peculiarity is to reinforce the lock of any entrance door into the house. It offers more security compared to other locks available in the market. This is because the multi-point lock has multiple locking points. To install a lock of this size, you definitely need to hire a locksmith expert. In this way, the professional locksmith will install the multi-point lock in the best possible conditions.

Today, multiple locks can be closed at up to 6 points in one go. However, the lock mode varies depending on the type of lock purchased. In addition, multi-point locks are designed for installation on solid doors. These carpentry accessories usually consist of several components, namely:

The chest: It usually houses the ceremony and the cylinder, 2 elements that make up the closing and locking of the multi-lock.
The Bolt: This is a movable metal part that inserts into the strike plate to ensure the door is locked. Today it is possible to find a deadbolt or a latch bolt. All multi-point locks offer a more efficient locking system. So don't hesitate to choose a deadbolt lock for more security.
The door opener: It usually picks up the deadbolt (bolt or frame) when the user activates the locking system of the multi-lock. With surface-mounted multiple locks, the striking plate is mounted on the wall. On the recessed lock side, the bolt engages in the headrest-mounted on the door frame.
The ceremony or bar: This is a metal part that guarantees the security level of the multi-lock. For optimal security, the ceremony or rod must be strong enough.

According to studies by locksmiths, the multi-lock is still one of the safest locks available on the market. Thanks to its security level, it significantly optimizes the closing and locking of the front door. Similarly, the multi-lock is the ideal carpentry equipment to secure the entrance to your home due to the presence of the bar, security cylinder and bolt. This type of lock is one of the best and helps limit home break-ins.

What different forms are there of a multi-point lock?

Multi-point locks come in different types of locks. Today you can choose either the pull lock or the handle lock. Whatever your preferences, you should know that the type of lock you choose can be combined with any type of front door. Multi-point locks are also easy to use and offer effective access control.

In terms of shape, the multi-point lock can be:

Vertical: The lock fits doors with wide jambs;
Horizontal: Multi-point locks of these shapes are specifically designed for exterior doors with narrow jambs.

The choice of shape varies depending on the front door. It is therefore important to consider some criteria before choosing the multi-point locks that are perfect for your installations. If you encounter difficulties, the ideal is to contact a professional locksmith so that they can give you the necessary clarifications.

Built-in or surface-mounted multiple locking system

Today there are several models of multi-locks sold on the Internet. The lock can be installed surface-mounted or recessed. On the other hand, the number of points where your woodworking equipment sits determines how secure it is and how resistant it is to break-ins. Regardless of which model you choose, your front door must be of excellent quality to benefit from the advantages of this type of lock.

The construction of recessed multi-point locks is carried out with the aim of installing high-quality front doors. On the other hand, surface-mounted locks are designed to be ideal for heavier and more robust front doors.

The multi-point lock

Recessed multi-point locks typically fit within the thickness of the front door to be discreet. Since the lock has a flat Cremona, it is installed along the door panel. However, please note that the built-in lock does not have good resistance to burglary and burglary. The lock's bolt only fits at the height of the front door frame. Therefore, no deadbolt locks near the ground are detected. If you want to replace your multi-point lock, be sure to use an identical model to make installing the lock easier. Installation therefore requires no modifications to the wooden door.

Surface-mounted multiple locking system

The surface-mounted multi-point lock is installed on the front of the front door. In fact, the installation of this type of lock is carried out on the inside of the house. His staff has a round woman and is visible. The Cremone is operated over the entire height of the front door. It is locked at the top of the door and also at floor level. Installing the surface-mounted multi-point lock is easy to do, especially for a professional locksmith.

In addition, installing the surface-mounted multi-point lock brings aesthetics to your interior. When you buy this type of lock, you can be sure that it will fit your door. This is because this carpentry equipment can be adapted to any type of entrance door (armoured gate, garage door, gate, etc.).

What protection should I have after installing a multi-point lock?

Regardless of whether it is an armoured door, a garage door or a gate, installing a multi-point lock guarantees you an optimal level of security. Here are some protective measures to benefit from installing this carpentry equipment:

Burglary protection: Multi-point locks are particularly strong and can effectively resist breakage, drilling and cracking of cylinders. By installing this type of lock, you will bring more security to your interior.
Protection against breakage: Multi-point locks are particularly durable because they are equipped with anti-breakage technology. These include those that consist of increasing security at the cylinder level. Even if burglars manage to grab the cylinders with large pliers, they will hardly be able to crack them.
Drill Protection: Nowadays, many burglars tend to use lock-picking techniques to open front doors. By installing a multi-point lock, you can be sure that you will not face such a situation. This is because the pins can only rotate in the event of drilling in a vacuum due to the integration of a rotating element into the locking cylinder.

Some tips for choosing the ideal multiple lock for your front door?

In order to benefit from the high security of multi-point locks, you must meet a few criteria to make the right choice. Here are some of them:

Know the opening direction of the front door

Although most multi-point lock models are reversible, you should be aware that some areas still require a specific opening direction to function. Here are some explanations you need to know:

Straight press: The lock is on the right side when the user presses the door;
Left Push: The lock is on the left side when the user pushes the door;
Straight Pull: The lock is on the left side when the user pulls the front door.
Left Pull Tab: The lock is on the right side when the user pulls on the front door.

Determine the number of points for greater security

On the market, you can find multi-point locks with 3.5 or even 9 points. So it's up to you to determine the level of security you want to bring to your home. However, this level needs to be given special attention. If you want to take full advantage of the advantages of a multi-point lock, you must equip yourself with a modern, high-quality door. Regardless of whether the front door is screened or not, the door openers must be installed carefully. In order to have more security with a multi-point lock, you should not think in terms of elements, but rather as a whole.

Certification A2P

If you want to be sure of the quality of the devices to be installed, it is important to check the A2P certification of the multi-lock you are purchasing. To have the greatest resistance, the ideal would be to choose the 3 star model. Locks of this size can withstand attempts to grab and break in for up to 15 minutes.

Also note that the A2P standard specifies the resistance time to lock picking, percussion and drilling. Here is a classification that should not be overlooked when choosing your multi-point lock:

A2P*: 5 min burglary resistance;
A2P**: 10 min burglary resistance;
A2P***: 15 min burglary resistance.

The different types of keys

In addition to the opening direction, the number of points and the A2P certification, the type of key that opens and closes the multiple locks also has a significant impact on the level of security to be established. If you want to opt for more security, you should use a reversible ball and pump wrench. Keys of this size are typically sold with a personal ownership card. The latter is essential above all for reproducing the key.

If you want to benefit from more security, you can opt for multiple lock keys whose ownership cards are only approved by manufacturers. In particular, no professional locksmith can reproduce these keys. However, some people want to introduce a standard level of security. If you are one of them, then using a dental wrench would be ideal. The latter is particularly easy to reproduce.

What tips are there for installing the multi-point lock?

To install a multi-point lock, you must definitely follow a few tips. For example, if you want to carry out renovation work, surface-mounted multi-point locks may be preferred. Likewise, the number of points should not be neglected as it contributes to the proper installation of the striking plates that house the screws. For example, it would be pointless to have armoured doors, A2P*** certified locks and strike plates installed on plasterboard walls.

Don't hesitate to protect the cremone of your surface-mounted multiple locks with a bar or bar cover. Such a practice allows you to make the connection invisible and add aesthetic care to your interior.

You may need to replace recessed multi-point locks with PVC or aluminium patio doors. At this level, you have to be very vigilant on the sides of the different locking points. If you do not do this, you may not be able to install the Cremone on your recessed multi-point lock.

Find the right latch for doors and furniture

noreply@blogger.com (CouHome) — Fri, 26 Apr 2024 20:18:00 +0000

They ensure security and help protect your own belongings - we're talking about latches for doors and furniture. And there are lots of them. We took a look at all the doors and furniture latches on the market and would like to briefly introduce them to you here.

That’s where it all began – the first castles

Since ancient times, people have wanted to protect their belongings from unauthorized access. Constructions were devised that made it possible to put a stop to theft.

The first recorded castles were made of wood and were developed by the Egyptians about 5,000 years before the birth of Christ. The Romans made the first pure metal latch. At this point, Jesus had already been dead for 100 years.

It took another 1,500 years until the first door latches were built. During the Thirty Years' War, two locksmiths developed latches at about the same time, the basic principle of which can still be found on room doors today. The bolt was moved with a handy key with a bearded profile.

In 1844, the American Linus Yale Senior developed the first cylinder latch. Cylinder latches with a similar structure can be found on most of today's common exterior doors.

Different requirements for latches

When it comes to an external door, the most important thing is that the latch or locking system is as difficult as possible for burglars to crack.

With room doors, it is sufficient to keep the curious little brother from snooping around in his sister's room. The brother won't come with heavy burglary tools straight away.

Even when it comes to locks on furniture doors, furniture flaps or drawers, burglary protection is not the main focus. The latch on your boss's desk certainly has to be more resilient than the wardrobe in the bedroom.

While locks and latches are intended to prevent unauthorized opening, catches and magnetic locks primarily have the task of preventing doors and flaps from opening automatically.

Part 1: Door Latches

When it comes to door locks, a distinction is made between latches for interior and exterior doors. Both types of doors generally have mortise latches. However, the type of security differs.

Different types of backup:

Bunted locks
Tumbler locks
Occupation locks
Locks for lock cylinders
Electronic locks

Front door latches are usually more difficult than room door latches. Doors to the bathroom or toilet can have a toggle on the inside to latch them instead of a key. There are also special latches for hotel and hospital doors as well as soundproof doors.

Mortise latch

The mortise latch is mainly used on house and room doors. It is also rarely used in furniture. Mortise locks are embedded in the back of the door (by prying or milling a pocket) so that only the latch faceplate with the bolt is visible.

The type of security ranges from the beard latch and the crew latch to the tumbler latch and cylinder latch. A distinction is made between mortise locks for rebated and butted doors.

If the door slams in bluntly, the faceplate lies in the middle of the latch case. On a rebated door, the faceplate is flush with the latch case on one side.

An important concept when ordering and installing locks is the backset. It indicates the distance from the centre of the door handle or keyhole to the outer edge (forend). Door locks are available with a backset of 25 mm to 100 mm. Room doors usually have a backset of 55 mm.

Buntbeard Castle

Beard locks are mainly used for room door locks. They have the least security. The doors can be opened with a simple locking hook or a bent wire.

If you don't want every young burglar to rummage through your things, you should opt for another type of security, such as a tumbler lock, crew lock or lock cylinder.

A deadbolt latch may not be used on the front door. The beard latch gets its name from the different, most colourful key shapes.

Occupation castle

The crew latch is more secure than the cuntbar latch. However, the door can also be opened with a cut key. The castle is a further development of the Buntbart Castle.

You could still come across such as lock-in barracks, older classrooms or youth hostels. However, it may not be used for front doors either. Crew locks have mounted tyres on the interior surfaces of the latch case to which the keys are matched.

Tumbler latch

Compared to the crew latch or the guard latch, the tumbler latch has a higher level of burglary resistance. The interior consists of sheet metal discs that have recesses in various places.

The key is used to raise the individual panes so that the recesses are all at the same height. Now a bolt attached to the latch can be inserted there and the door can be opened.

Safety depends primarily on the number of panes. Cheap latches with few panes can be opened relatively quickly. Tumbler locks are used, for example, for safes.

House entrance doors may also be equipped with a tumbler latch, provided they are equipped with a change latch.

Cylinder latch

The cylinder latch is a mortise lock that is equipped with a latch cylinder. Locking cylinders are manufactured in a wide variety of shapes, materials and dimensions.

Common forms include:

Oval cylinder
Round cylinder
Profile cylinder

A latch cylinder consists of a housing and a rotating cylinder core. With good locks, at least five pairs of pins in a row lock the cylinder core against the housing.

By inserting the key, the differently designed pins are pressed into one plane and reveal a dividing line. This allows the cylinder core to be rotated relative to the housing.

The cylinder lock is used wherever greater security is required. This can be with room doors or furniture, but especially front doors are equipped with a cylinder lock. However, front doors require a change, which means they must be equipped with a change lock.

Magnetic latch

Magnetic locks are classified as security locks. They have several tumblers, which then have to be unlocked individually according to the locking code so that the bolt can be activated.

Like the lock cylinder, the magnetic latch also works with pins. But as the name suggests, magnets also play a role. There are three different modes of operation: sliding magnets, rotating magnets and tumbling pins.

The first magnetic locks worked with sliding magnets and the principle of attraction and repulsion. The magnetic pins only unlock if there is a suitable opposite pole on the key.

With the rotating magnet principle, the pins are rotated by the key and release a mechanism when they are in the correct position. The wobble pin principle involves moving six pins into the correct position using a magnetic key so that they fit into a template.

The magnet on the key can have 6 or 8 different positions, allowing a variety of combinations. The latch is therefore extremely burglar-proof.

Interchangeable latch

Front doors must be equipped with a changeable latch or an electronic or magnetic latch. The type of security for a removable latch can be a tumbler lock or a cylinder latch.

The term “change” means that the lock latch can be operated with the key. So you don't have to press a door handle to unlock the door. Doors with such locks are usually combined with a button or handle on the outside.

Electronic locking systems

Electronic locks are an alternative to the mechanical systems presented. Such an electronic locking system initially consists of electronic door components, such as the electronic door lock or a wall reader.

This requires locking media to identify access authorization - this can be a transponder, a key card or even a fingerprint. Finally, an administration tool is also necessary, such as software or an online portal for central key management.

Part 2: Furniture locks

As already mentioned, the design of a furniture lock depends on whether it is in office furniture or private furniture. Locking cylinders or even entire locking systems are preferred in office furniture construction.

A locking system is a combination of locking cylinders and different keys. Numerous different locks are also available for the living area:

Screw-on locks
Entry locks
Mortise locks
Push rod locks
Espagnolette locks
Flap locks for drawers
Casket locks for small jewellery boxes

Screw-on lock

This furniture lock is screwed onto the back of the door. The bolt engages in a striking plate that is embedded in the side of the furniture or the door frame. On double doors, the bolt goes behind the second door. This is usually reinforced at this point.

The type of closure of the screw-on latch can be different. Depending on how much emphasis is placed on security, there are grooved, tumbler or cylinder locks.

Drill lock

The drill lock is also attached from the back like the screw-on lock. However, a suitable drill hole must first be drilled into the furniture door. The bolt in turn engages a striking plate.

Entry lock

Inlet locks are recessed into the back of the door so that the lock plate is flush with the back of the door. The bolt of the latch fits into a striking plate, which is embedded in the side of the body for doors with one leaf and in the edge of the other door for double doors.

Espagnolette lock

This furniture lock locks the furniture door at at least two points. Espagnolette locks consist of the latch case, the espagnolette and the locking hooks.

The locking or gripping hooks are attached to the upper and lower ends of the rotating rod. You reach behind the locking bolts that are screwed into the top and bottom of the piece of furniture.

On cupboard walls, for example, espagnolette locks can also be equipped with a rotary handle. A key is then not available.

Push rod lock

The push rod lock has a similar structure to the espagnolette lock. It is used, for example, for cabinets.

As the name suggests, the bars do not rotate, but rather slide into locking sockets in the top and bottom floors. In the middle is the lock case, which can be screwed on or flush.

Some push rod locks also have a latch on the lock case so that the door is locked in three places. A triple lock is particularly suitable for high doors.

Push bolt

Garden gates, stable doors, caskets or boxes can be locked using the sliding bolt. Tight closure is less of a priority.

However, this is also possible with a padlock for many push bolts. A distinction is made between cranked and straight bars. Offset deadbolts are used for butt-opening doors.

padlock

Padlocks come in many sizes and different locking methods. Padlocks with a locking cylinder are less easy to crack.

However, it must always be taken into account that on a cheap padlock the shackle can be cut with bolt cutters. Many a bicycle has already changed hands in this way.

Hook latch lock

Like the mortise lock, the hook latch lock is inserted into a pocket by prying or milling. Instead of a bolt and latch, however, the lock has a hook bolt that can be moved up and down.

The hook latch lock is suitable for effectively locking sliding gates and sliding doors. When the door is closed, the lock engages. To open the gate, the hook must then be lifted.

Door Locks Demystified: A Simple Guide to Choosing the Right One

noreply@blogger.com (CouHome) — Thu, 25 Apr 2024 20:46:00 +0000

As a central security component of our apartments and houses, we use door locks every day. Here we present the 8 most common door lock types with their respective functions in detail.

Which door lock for which door?

Door locks are an important part of security in apartments and houses and are used by us almost every day. There are many different types of door locks, some of which differ greatly in their construction and functionality.

Some of the most common types of door locks are mortise locks, tubular frame locks, and padlocks. Mortise locks are the most commonly used locks for house, apartment and room doors. Tubular frame locks are mainly used for gates and wickets, while padlocks are suitable for shed doors or cupboard doors.

But digital identification media are also playing an increasingly important role in the age of digitalization, as they have numerous advantages over manual locks. It is clear that the variety of lock types is just as large as their functionality and appearance.

In order to get a better overview of the different types of door locks, we would like to explain the eight most common models as well as their specific advantages and areas of application in more detail.

The 8 most common door lock types at a glance

1. Mortise lock

The mortise lock is a common lock model that is installed in stub, rebate or tubular frame doors and, depending on the design, uses different locking mechanisms, including tumbler locking mechanisms, guard locking mechanisms or profile cylinder locking mechanisms.

The lock is embedded in the door leaf via a lock pocket and consists of several components, including the lock case, the lock cover and the latch. With this type of door lock, only the lock latch (also called catch) and the bolt block are externally visible. The locks are screwed to the door using the so-called faceplate, a vertical metal strip. Locking is done by closing the door or turning the key in the lock case, although this mechanism is often found in combination with door handles or door handles. The lock is embedded in the door leaf and requires a recess, which can result in weak material in the lock pocket area.

The mortise lock is particularly often used as an uncomplicated locking device in house and apartment doors, but they are also used outdoors.

In addition to being easy to install, they also offer the advantage of a relatively high level of burglary protection as they cannot be easily unscrewed. On some models, multiple locking is also possible, in which several bolts engage in the striking plate, making it more difficult to pry open and drill open the door. It is also possible to install anti-picking or anti-drilling protection.

However, the disadvantage of a mortise lock is the loss of keys, as the entire lock has to be replaced in an emergency and it can also be manipulated and opened with simple tools.

2. Tubular frame lock

With a similar structure to the aforementioned mortise lock, the tubular frame lock offers a significantly more robust design and is primarily used in metal frame doors and gates, but also in fire doors and doors that generally have high security requirements.

Basically, a tubular frame lock is a mortise lock that is installed in the profile tube of the frame and was designed specifically for installation on tubular frame doors. It also consists of a lock case, latch, bolt and strike plate, but in contrast to the mortise lock it has a much smaller overall depth and makes do with the space in the tubular frame.

Tubular frame locks are widespread in Germany and are usually used in apartments, offices and public buildings. Their advantages are the space-saving design, the very high level of security against burglary and the flexibility of possible uses, including fire protection and soundproof doors. As with a mortise lock, losing a key also means a complete replacement of the lock. Installing a tubular frame lock is also very time-consuming and requires special tools and know-how.

3. Profile cylinder lock

A profile cylinder lock is the most common type of locking cylinder, which is usually used in front doors, apartment doors and office doors, but also offers other possible uses.

In addition to the housing with a rotating cylinder core inside, a profile cylinder lock consists of a lock bit, core pins and pin springs. There are small metal pins in the rotating cylinder core, which are pressed by springs from bottom to top into the locking gear, thus blocking it. This can only be turned if a key with the appropriate profile is inserted. The locking lug, a lever on the cylinder core, rotates and engages with the lock mechanism so that the latch and bolt are pulled back.

The profile cylinder includes a certain number of keys, all of which have the same locking mechanism. Profile cylinders also enable the lock and locking mechanism to function. While the lock does the actual locking, the locking cylinder takes over the function of driving the bolt and securing the locking mechanism against unauthorized opening attempts or foreign keys.

In addition, they have a wide range of advantages, which makes them successful. Profile cylinder locks offer various levels of security, ranging from conventional security cylinders to those with electronic security elements and armour. This means you can easily ensure a high level of security against break-in attempts. In addition, they are easily interchangeable and can be replaced with a new cylinder without any problems (e.g. if a key is lost) without having to replace the entire lock.

4. padlock

A padlock is a lock that is used for simple locks and does not require installation. It is simply attached to a union latch using a U-shaped bracket that covers its own mounting screw heads.

Broadly speaking, the lock consists of a shackle, the locking cylinder and the housing, whereby the shackle represents the movable member of the lock and is inserted into the housing for locking. The lock cylinder is the part of the lock in which the key is inserted to unlock the shackle again. The housing surrounds the locking mechanism and protects it from damage, tampering and the effects of the weather. As an alternative to the typical serrated key, there are also designs that are designed as a combination lock or as a digital padlock variant.

Padlocks are available in different sizes and strengths, and their design also offers a high degree of flexibility and ease of use. They are therefore used in various places, including cellar doors, lockers, toolboxes, garden fences, chests and many more.

However, the comparatively simple design results in a number of disadvantages, which particularly concern safety. In contrast to a permanently installed lock, a padlock can be cracked relatively easily using tools such as pliers or bolt cutters and therefore only offers limited protection against break-ins and theft. Losing a key can also become a significant problem because the profile cylinder cannot be replaced. In addition, you should always pay attention to good quality when purchasing, as cheaper locks are usually not weather-resistant and rust. A padlock can also be bulky and therefore difficult to handle.

5. Screw-on lock

The screw-on lock is a type of lock that screws onto the back of a door or drawer rather than being installed into a recess. It is often used for smaller doors, drawers, garden gates and furniture as it is easy to install and requires no special tools.

It consists of a strike plate, a latch and a lock cylinder, whereby the latch is operated by turning the appropriate key in the lock cylinder and engages the strike plate to lock the door. The mechanics are covered by a lock case. In contrast to the mortise lock already mentioned, the screw-on lock does not require a recess in the door and is also much easier to install. Screw-on locks are usually made of galvanized metal and are suitable for outdoor doors and gates as they are resistant to weather influences.

However, they do have some disadvantages that should not be ignored. They offer less security than other types of locks and are more susceptible to tampering and break-ins. The attachment is also not suitable for all doors as they require a strong material and also damage the surface of the door as holes are required for attachment.

6. Circle bolt lock

A circular deadbolt lock is a special lock specifically for use on sliding doors and includes three available variants, the cambolt lock, profile cylinder lock and WC circular deadbolt lock. Since the straight bolt of a standard lock would not close a sliding door correctly, a curved compass or hook bolt is necessary. In addition, the circular bolt lock can be equipped with a suitable spring handle, which is suitable for sliding doors that open into the wall.

Sliding doors with their associated locks are particularly advantageous in living rooms and offices because they save space, are easy to handle and visually enlarge the given space. The variety of possible uses is therefore large; the door can disappear on or into the wall and offers visual elegance.

However, they only have a low level of burglary resistance, are completely unsuitable for house entrances and, with sliding doors on the wall, the door leaf has to run onto a stop post in order to be lockable at all. This can disrupt the overall picture.

7. Buntbeard Castle

A popular door lock with a simple design is the beard lock, which is primarily used in interior doors. The associated keys have a high variety of (“colourful” or “versatile”) key shapes, which gives this type of lock its name. Both the key shape and the keyhole are intended to be visually reminiscent of a wavy beard.

The central component of the warded lock is the lock cylinder. This consists of various parts, such as the housing, the core and pin tumblers. In order to be able to close the door, there is an additional latch inside, which extends when the lock is pressed and engages in the striking plate. With the appropriate key, the pin tumblers inside can be unlocked or locked by turning.

The lock has a barrier in the form of a plate in front of the locking channel, which only allows the key with the appropriate profile to pass. In total, there are 64 different profiles for beard locks in Germany.

Caution is advised when it comes to security. Beard locks can be opened relatively easily with a locking hook and are therefore only suitable for interior doors without security requirements.

8. Toilet lock/bathroom lock

A lock with the most common use that everyone has used at some point is the simple toilet or bathroom lock, which stands out unmistakably with the display “vacant”, “occupied” “green”, or “red”. The toilet lock is used to lock the door of a public or private toilet cubicle from the inside and is intended to provide privacy to users. The lock is equipped with a toilet set, i.e. with a rotary knob on the inside and a small knob with a recess on the outside. Depending on the model, a turning or sliding rule can be used here.

Overall, the lock is quite simple, it is single-turn, i.e. it is closed by turning it once and does not require an associated key.

The bolt is closed by activating the turner, known in technical jargon as the “olive”, and moving a square pin. The bolt finally snaps into the recess provided or in the strike plate on the door frame. In an emergency, it can also be opened from outside using a small notch and the appropriate tool.

The name may suggest that it is intended exclusively for toilet facilities. Because they are easy to use and practical, they are also used in changing rooms, for example, as no high safety standards are required here.

Determine the opening direction of a door

noreply@blogger.com (CouHome) — Thu, 25 Apr 2024 17:47:00 +0000

How should a particular door be hinged? Left or right? The answer depends on the door hinges – and this connection is defined by DIN. This makes it easy to determine the required door stop.

These factors determine the door hinge: left or right?

Room doors, cupboard doors, front doors or windows basically have a predetermined direction in which they open and close.
The DIN left or DIN right door stop always depends on the side on which the door hinges (hinges) can be seen.
Whether you should attach the door stop to the left or right depends on the practice. The door should not block other entrances when opened. The optimal door direction is often indicated in the floor plan.

Example: If the hinges are on the right when the door is closed, the door stops on the right. This door is therefore considered to be hinged on the right (DIN right). The same applies to a “DIN left” door.

DIN standards for door hinges

The determination of a door hinge for a specific door is derived from DIN 107 or ÖNORM B 5328. The supplementary DIN EN 12519 has been helping as a European standard for some time now.

These standards contain terms to prevent confusion: door stop DIN right or DIN left (in short: DIN left, DIN right). The opening of a door can be determined immediately using these standards:

The stop is always on the side of the door with the door hinges (hinges), whereby the hinges are visible when the door is closed.

Example: If the hinges are on the right when the door is closed, the door stops on the right. This door is therefore considered to be hinged on the right (DIN right). The same applies to a “DIN left” door.

On most doors, the side of the stop can be identified on the door handle: If the handle points to the right, DIN applies to the right - and correspondingly to the left.

The exceptions when determining the door hinge

This practical rule works almost always and immediately for room doors, but not for many front doors: These doors often appear as interchangeable sets where the handle does not necessarily indicate the correct stop. That's why the DIN remains important - it immediately results in the correct stop.

The swinging of the door in question is also of interest here: doors almost always swing open inwards. On the inside of the door, the hinges are visible even when the door is closed.

Some exceptions require special attention: doors in very small rooms and especially locker doors. These doors make the most of limited space by swinging outwards. Escape and emergency exit doors also swing outwards - so a fleeing person pushes them open while running instead of stopping to pull them.

These exceptional doors have their hinges on the outside, which is why the phrases “DIN right outwards” and “DIN left outwards” apply. However, all other properties of the door remain unchanged, which is why “DIN right outwards” corresponds to DIN left and “DIN left outwards” is to be understood as DIN right. Various building regulations regulate the associated requirements for escape routes, such as the Assembly Place Ordinance.

Overall, the striking direction of a door (also: impact direction, and opening direction) refers to its two directions of swing: the door swings to the left or right and it swings into or out of the respective room.

Floor plans determine these two directions for each hinged door in a building. This results in DIN left or DIN right for each door.

Replacing the door latch: You need to pay attention to these features

noreply@blogger.com (CouHome) — Tue, 23 Apr 2024 19:04:00 +0000

These instructions will show you how to change the door lock on a room door. Find out here how to correctly remove the mortise lock step by step and install a new lock.

Changing the door lock – what should you pay attention to?

With frequent use, door locks, like common mortise locks, wear out. The lock starts to get stuck, gets stuck or can no longer be opened or closed at all. You should replace the door lock in time to continue using the door smoothly. You also save on expensive locksmith services and maintain the security of your home.

Door locks are available in different designs for locks for interior, apartment and front doors. Simple warded locks are usually used for doors inside the apartment. House and apartment doors have tubular frame locks, mortise locks, security locks or self-locking locks.

Find out now in the step-by-step instructions how to determine the size of the lock cylinder and find out which cylinder you need to replace the door lock. Then remove the lock cylinder and the door handle to take out the old door lock. Finally, you install the new door lock using the instructions in the same way as you removed the old door lock, only in reverse order. In addition to the instructions, our video shows you exactly how to do this.

7 steps to Change door lock

1. Determine the size of the lock cylinder

At a glance

Measure the old lock cylinder
Determine the dimensions of the old door fitting

That's how it goes

Open the door and look at the lock on the edge, also known as the door rebate. The adjusting screw is located directly under the latch at the level of the cylinder. Starting from the screw, measure in both directions to the end of the fitting. Write down the inside length and the outside length. These values result in the required size of the locking cylinder.

Note: Door leaves are usually constructed asymmetrically and require cylinders with sides of different lengths. That's why it's important to measure both sides. However, you can later use the lock cylinder in both directions. For example, you can buy a double cylinder with the values 30/40 or 40/30. The only exception is the knob cylinder: here the inside length must correspond to the knob side length.

If you want to replace the door fittings at the same time as replacing the door lock, then also determine the distance from the centre of the cylinder up to the centre of the doorknob or door handle.

Tip: The value is often 72 mm or 92 mm.

2. Loosen the adjusting screw and remove the locking cylinder

That's how it goes

When replacing the door lock, unscrew the adjusting screw completely. Then remove the lock cylinder by turning the key about 20° to the right or left.

If the locking cylinder is stuck, you can loosen it by shaking it slightly. If the cylinder is really tight, it often gets stuck on the fitting. Slightly loosen the screws on the fitting and try to remove the lock cylinder again. If the removal doesn't work at all, you have to remove the fitting - but depending on the door fitting and lock, this is necessary anyway.

3. Remove the door handle and square

If necessary, unscrew door fittings

That's how it goes

Now remove the door handle and the key and take out the square that is attached to it or inserted individually. The latter runs through the entire thickness of the door, the lock and the fittings and moves the lock using the handle.

If necessary, remove the protective fittings to remove the square. To do this, loosen the screws and pull off the fittings. Depending on the manufacturer, the covers of the protective fittings are attached or secured with small screws, which you also unscrew. The same applies to the possible hexagon socket screw on the underside of the handle, with which the square is fixed.

4. Remove the mortise lock

At a glance

Remove the screws on the lock
Take out the door lock

That's how it goes

Once the square has been removed, loosen the two screws at the top and bottom of the lock - they are again on the door rebate side. Now you can pull out the lock and take it with you as a sample when buying a new one.

5. Install a new lock

At a glance

Insert door lock
Fix screws

That's how it goes

The new lock is installed in the reverse order of removal. So you first insert the new door lock into the milling on the door rebate side and fix it with the top and bottom screws.

6. Install fittings and square

At a glance

Screw on protective fittings
Insert square, fix and test

That's how it goes

Now mount the removed fittings and put the square or the handle together with the square back on. If necessary, fix it with the Allen screw at the bottom of the handle when installing. Then you test whether the square turns when you press it.

7. Tighten the adjusting screw

At a glance

Insert cylinder with key
Tighten the adjusting screw
If necessary, drill holes for new door fittings

That's how it goes

Now put the cylinder back in the correct direction according to the values determined before removal. Test all locking functions with the key and finally tighten the adjusting screw. If you want to replace the door fittings at the same time, they often require different drill holes. Use a drilling template to carry out these holes.

Note: When choosing new door fittings, make sure that existing holes are covered and that there is enough door material for fastening.

Tip: Increase the security of your front door with an additional lock and a door viewer. Both elements are easy to assemble and make your apartment or house even safer.
