Lock cylinder: what it is, types, which one is better

A lock cylinder is the main mechanism for opening and closing doors or other locking devices. It is a cylindrical metal or plastic base with pins or rods inside that correspond to the key. When the correct key is inserted into the cylinder and turned, the pins rise to a certain level, unlocking the lock.

Features of lock cylinder design

Lock cylinders can have different configurations and security levels. They are installed in homes, offices, and cars—all mechanisms have a similar operating principle. A lock cylinder usually consists of the following main components:

• Base (body) - a cylindrical metal or plastic shell that contains the internal mechanisms of the lock.
• Pins - metal parts located inside the cylinder that interact with the key. The pins rise or fall when the key is turned, allowing the lock to be unlocked.
• Anti-impact plates prevent the lock from being broken.
• Armor plate - protects the cylinder from physical damage or break-ins.
• Internal mechanism that connects the pins and locks the lock when closed.
• Rotor or carriage - part of the lock that rotates when the key is used to open or close it.
• Key - a tool that is inserted into the cylinder and turned to activate the lock.

The design of lock cylinders may vary. Some models do not have an armored plate. And in some cores, discs are used instead of pins. Such additional elements increase the strength and security of the lock.

Types of lock cylinders

Lock cylinders come in different designs depending on their purpose and level of protection. The main difference is in how the lock is opened. Types of cylinders by opening type:

• A single cylinder is the most common design, where the key is inserted on one side only.
• In a double cylinder, the key can be inserted and turned on both sides, providing two-way locking of the lock.
• A half cylinder with a keyhole on only one side. On the other side, there is a fixed or special mechanism.
• A push-button cylinder with a button mechanism on one side.

Pin and disc cores are two different types of mechanisms that are often used in locks. A pin core or pin cylinder is a system with pins that rise or fall when the key is turned. The mechanism has pins of different lengths that correspond to the key combination. This type of core is more common and widely used in door locks around the world.

In a disc core, discs are installed instead of pins. They have notches that must match the protrusions on the key to open the lock correctly. This is a more complex design, which makes it more resistant to break-ins.

Which cylinder is better

The best type of cylinder for a lock depends on specific needs and conditions of use. For a high level of security, it is recommended to choose cylinders with modern protective mechanisms and armor plates. These are profile or anti-vandal cylinders.

If ease of use is important, you can choose cylinders with additional features. These are combination cores, which can be opened using both mechanical keys and electronic devices. It is important to read reviews on the Internet about different models of cores and their features.
