Lock Rekey

A GLOSSARY OF ESSENTIAL LOCKSMITH TERMS

When rekeying a lock, a locksmith removes the lock cylinder’s pins and springs and replaces them with fresh components that work with the new key. On the other hand, essential control is just keeping track of all the keys used to open locks. Once keys are loaned out, essential control is gone.

Key Bitting

This means the actual essential cuts. This is typically stamped on the key’s “bow” or head on new locks.

Key Bow

Essential bow is the term for the top of the key, frequently utilised as the handle or grip.

Broach

The term “broach” describes the grooves on the side of the key that are unique to each manufacturer’s keyway.

Cam

The component on the lock’s back, known as the cam, engages the lock bolt mechanism.

Grand Master Key

This key operates all locks that are keyed according to the established master key system. GMK is frequently stamped on the key.

Sub Master Key

This critical functions in a master key system under the Grand Master Key for a particular group. For instance, we may have a sub-master for every building floor with numerous floors. Unlike the Grand Master Key, which opens all locks in the same building, this key will only open doors on that floor.

Change Key

This is the name given to the individual keys below the Grand Master and Sub Master Keys in the master key system.

Cross Keying

This is when one or more keys open a lock in a master key system. This happens frequently in an uncharted master key system when the following key is chosen randomly inside the system without referencing the charted system. This represents a significant security violation and should never be used.

High-Security Key

These keys offer the highest level of security. These keys can only be reproduced or made by someone with valid identification and are often controlled by the locksmith under contract with the lock manufacturer. These keys are typically distributed along with a critical control card. This card must be shown to the locksmith when new keys are needed. 

Cylinder Bumping

When bumping it, the key is initially put into the lock’s keyway by one notch (pin) or pin short of full insertion. The key can be pushed farther into the keyway by pushing it inward. All critical pins in the lock receive a slight impact force from the bump key’s precisely crafted teeth. The driver pins receive this force from the key pins, which remain stationary. One may visualise this physical motion by witnessing the identical result on Newton’s Cradle desktop toy. 

Due to the high degree of elasticity in the pin movements, the driver pins briefly ‘leap’ away from the key pins and move higher than the cylinder (shear line of the tumbler) before being forced back by the spring to rest against the key pins again. Even though the key and driver pins only separate briefly during the slight impact, if a light rotational force is continuously applied to the key, the cylinder will turn during this brief period, allowing the lock to be opened while the driver pins are elevated above the keyway. 

Lock bumping simply needs a split second to unlock the lock. Although the power of the collision may create an indentation on the face of the cylinder, the lock is not visibly harmed. You can also utilise specific clicking and vibrating instruments made for bumping. These permit repeated bumping against locks that have been promoted as having “bump-proof” capabilities. Key-pin locks can only seldom be bumped. Abloy locks use rotating discs and are the only ones with practically “bump-proof” cylinders since they don’t require pins or springs.

Lock Picking 

Lock picking opens a lock without using the original key by adjusting the lock’s parts. Although lock-picking has a reputation for being used with malice, it is a necessary skill for the professional field of locksmithing. Lock-picking tools are forbidden to be owned by most people in some nations, such as Japan; nevertheless, they are available and lawful to own in many other nations as long as they are not intended for use in criminal activity.

Drill Resistant

This refers to a rigid plate or pins in a High-Security lock that will stop a drill bit from penetrating the cylinder core. Regular locks are composed of brass and are easily bypassed through drilling. For instance, the front of the Abloy High-Security locks cylinder has a stainless steel drill plate.

Key Code

This is often the code stamped on the head of the key, though occasionally, as with most office furniture, it may also be stamped on the cylinder’s face. To create a key from scratch for the lock, this blind code is utilised in conjunction with software to obtain the key cuts and appropriate key blanks. Not all numbers on a key’s head correspond to critical codes. They frequently refer to genuine key bitting (key cuts). For convenience in ordering new keys and to identify the type of lock key used, it is sometimes referred to as a master key system.

Key Control

Only a High-Security Locking System offers critical control. The keys, however, are patent-protected against copying. According to the conditions of the agreement with the manufacturer of High-Security Locks, only the locksmith in possession of these keys is permitted to make these keys.
