Q&A/Glossary

A lock and a cylinder are two distinct components of a locking system, although they are often confused. Here are the main differences between the two:

1. The lock :

Definition: The lock is the complete locking mechanism installed on a door. It comprises several components, including the lock case, bolt, strike plate and cylinder.

Function : The lock operates the mechanism that locks or unlocks the door. It receives the action of the key (via the cylinder) to move the bolt (the part that fits into the strike plate on the doorframe) and thus block or unlock the door.

Types of locks : There are several types of lock, such as mortise locks (hidden in the door), surface-mounted locks (surface-mounted), or multi-point locks (with several locking points) ...

2. The cylinder (or barrel) :

Definition: The cylinder is a specific part of the lock where the key is inserted. It is a removable and interchangeable component.

Function : The cylinder is the element that recognises the key and operates the lock. When the correct key is inserted and turned, it aligns the pins inside the cylinder, allowing the rotor to turn and actuate the lock mechanism.

Cylinder types : There are single cylinders (key on one side), double cylinders (key on both sides) and knob cylinders (key on one side, knob on the other). They can be of different sizes and levels of security (for example, with anti-drilling or anti-pick protection).

Summary:

The lock is the complete device that locks the door.
The cylinder is the part of the lock into which the key is inserted and which operates the locking mechanism.

There are several types of armoured door, adapted to different security needs:
Single-leaf armoured door: This is the most common model, consisting of a single reinforced door, ideal for standard entrances to flats and houses.

Double-leaf armoured door : Made up of two leaves, this door is used for wider entrances, such as those to buildings or houses with spacious entrances.

Armoured fire doors : As well as protection against burglary, it offers fire resistance, useful for commercial and residential buildings.

Armoured glass door : Includes one or more panels of armoured glass, combining security and aesthetics while letting in light.

Acoustic armoured door : Specially designed to reduce noise, ideal for city flats or offices.

The choice of security lock depends on your desired level of security and the type of door:

Multipoint lock : Recommended for entrance doors, this lock locks the door at several points (3, 5 or 7), offering enhanced security.

High security cylinder lock : Includes an anti-drilling, anti-pick and anti-pull cylinder. Ideal for those looking for optimum security.

Electronic or connected lock : For secure, modern access management, this lock can be opened using a smartphone, a card, a code ...

Door block : This is a complete unit comprising the door, frame, hinges and often the lock. The door unit is ready to be installed in a single piece in a wall opening.

Door leaf : Refers only to the moving part that opens and closes. It requires a separate frame to be installed correctly.

From the inside : Install an additional lock or a security bar to reinforce the lock. Use an optical peephole to see who is at the door without opening it.

From the outside : Choose a high-security cylinder and fit a cylinder protector to prevent drilling attempts. Install reinforcements to protect the door unit against crowbar attacks ...

To secure a house door :

• Use an armoured door or add reinforcement plates to an existing door.
• Installing a multi-point security lock.
• Use a high-security cylinder and a cylinder protector.
• Add an optical peephole to check visitors.
• Consider alarm systems or surveillance cameras to warn you of a break-in in progress.

The role of a fire door is to delay the spread of fire and smoke between different areas of a building for a specified period (e.g. 30, 60, 90 minutes). It is essential for the safety of occupants, facilitating evacuation in the event of fire and limiting material damage.

In Belgium, there are certifications that confirm whether the door is fireproof or not, as well as its resistance time.

• If the building or renovation permit was issued before 7/2022, the door may comply with standard NBN 713.020 and must be Benor ATG-certified.
• If the permit is issued after July 2022, the door must comply with the EN 13-501-1 standard, be classified Ei 1 and may be classified Benor ATG (manufacturing control by an independent body).

To duplicate a Lince key, simply :

As the key is protected by patent, our liability is engaged. For the copy of the key we require the following documents depending on the model:

• Model Z: a copy of the ownership card (with the key code)
• Model X: a copy of the ownership card (with the key code) and identity card, together with the national number.
• XA1 model: a copy of the ownership card, the code shown on the head of the key (on one side) and the identity card as well as the national number.
• C5, C6, C7 or W model: a copy of the ownership card, with the code shown on the head of the key (on one side), which is different from the code on the card, and of the identity card, together with the national number.

To secure a lock :

• Use a high-security cylinder that is at least resistant to picking, drilling and tearing.
• Install a cylinder protector to protect the mechanism against attempted break-ins.
• Add a reinforcing plate around the lock to protect it from attack by crowbars, screwdrivers, chisels, etc.
• Use armoured fittings to increase the strength of the lock.

The term armoured door is simply a synonym for a burglar-resistant door, which is the more correct concept.

Armoured door" is more akin to a door that has been reinforced, which is not the case with G-Block doors, which are directly designed in their structure to resist.

Unlike a detection system that warns you of an intruder, a security door is a protective barrier against break-ins. The intruder remains outside the area to be protected.

A safety lock is a lock designed to offer enhanced security, often used for entrance doors. It incorporates complex mechanisms such as reinforced cylinders and multiple bolts, and is resistant to burglary techniques such as picking, drilling and tearing.

A multi-point lock locks the door in several places (usually three, five or seven) along its height, offering increased security. It is particularly effective at distributing the force applied in the event of an attempted break-in, making it more difficult to force the door open.
