Lock inserts are components used in lock systems designed to fit into the lock’s keyway. They are usually made of metal and, when inserted into the lock, create a unique keyway profile that matches the key used to unlock the lock.

Lock inserts can be used in various lock systems, including padlocks, latches and cylinder locks. They are also interchangeable, meaning several locks can be opened with the same key or a key specific to a particular security.

In addition to the unique, essential profile design, the inserts can provide additional security features, such as resistance to picking and drilling. For example, some high-security locks use special inserts designed to make the lock more resistant to picking and other attacks.

Overall, inserts play an essential role in the security and functionality of many types of locking systems, helping to ensure that only authorised persons have access to the protected area.

Locking systems use different locking inserts, each designed to provide other functions and benefits. Here are some examples:

Standard inserts

These are the standard inserts used in most locking systems. They create a key profile that matches the key used to open the lock. In addition, standard inserts are usually interchangeable, meaning the same key can be used to open several locks.

Master key inserts

These inserts allow a single key to several open locks with different keyways. They are usually used in commercial or industrial environments where different areas or departments must be secured with other keys.

Limited key inserts

These inserts have key slots designed to prevent unauthorised key duplication. The key profile is unique, and a particular key is required for copying.

High-Security Inserts

These inserts are designed to provide increased resistance to hacking, drilling and other forms of attack. They may have complex keyways, additional pins or sliding locks, or other features that make them difficult to compromise.

Interchangeable core (IC) inserts

Allow easy lock centre removal and replacement without disassembling the entire lock. This feature is practical for large organisations where frequent re-keying is required.

Removable core inserts

These inserts allow easy removal and replacement of the lock core without needing a key. This feature is useful when quick access, such as emergency exits or fire doors, is required.

Overall, the type of insert used in a locking system depends on the application’s specific requirements, such as the level of security required, the number of keys needed and the frequency of re-keying.

Industrial locking systems often require a high level of security; therefore, special inserts are often used. An example of such an insert is the Bundesbahn (BB) insert, a little key slot insert used in various industries, including railways, power plants and government facilities.

Bundesbahn (BB) inserts

The BB insert has a unique, patented keyway profile and can only be copied by authorised manufacturers. In addition, it uses a combination of pins and sidebar mechanisms to provide increased resistance to prying and other forms of attack.

Other inserts commonly used in industrial locking systems include:

Medeco inserts

These high-security inserts use a patented keyway and pin recesses to resist prying, drilling and other forms of attack.

Schlage Primus Inserts

These high-security inserts use a dual lock design and patented key control to prevent unauthorised key duplication.

ASSA Abloy Twin Inserts

This replaceable core insert allows quick and easy rekeying of locks without disassembly.

Mul-T-Lock inserts

These high-security inserts feature a unique pin-pin design and telescopic pin technology to resist picking and other forms of attack.

Overall, the type of insert used in an industrial locking system depends on the level of security required, the number of keys required and other factors specific to the application.
