5 Commercial Lock Repair Terms You Didn’t Know

When it comes to the security of your house, it is essential that you know the terms related to it so that you don’t look stupid when you approach a professional locksmith for security services. It is always beneficial to know how things around your house operate and what are they called. Understanding how different elements operate together to enable the door handle and lock to work can always empower you to fix small problems on your own feet. Here are five commonly used commercial lock repair terms that you should be aware of.


The term ‘keyway’ indicates how the shaft of the key is cut. It basically determines to check whether the key is compatible with a lock or not. If we talk about variety, they are also available as interchangeable keyways and mostly vary from lock to lock and manufacturer to manufacturer. Connect with a professional locksmith like us at Cheetah Locksmith, where we can effectively help you to check if your keys are compatible with your locks or not.

Lock body or lock cylinder

This is the element of the door lock where the key is inserted to operate. During locking, the lock cylinder engages a series of spring-loaded pins that prevent the cylinder from turning. On inserting the key, the uneven edges push the pins upward to fit the key’s height in the location. On recognizing the accurate key, the pins move into their proper positions. This ultimately indicates the cylinder to open, enabling the bolt to move and allowing you to open the door.

Box and strike plate

The box is a small square-shaped hole in the lock cylinder which is built to hold the bolt safely in the doorframe when the lock is engaged. The strike plate is a metal plate that attaches to the door frame. Its purpose is to guide the bolt into the frame box and offer additional reinforcement to the locking mechanism.

Bump-proof locks

To understand about bump-proof locks, you need to first know about ‘bumping’ which is known as a technique that is mostly used by burglars to bypass a lock without the use of advanced commercial tools. Since it is a popular means used by burglars, professional locksmiths have devised a new locking mechanism called ‘bump-proof locks’ to combat this growing problem. Bum-proof locks contain a high-security feature design that cannot be picked or bumped open easily by savvy thieves.


DND stands for ‘Do not Duplicate’. You can write this on your lock indicating that you do not wish that anyone makes another copy of the key. This mostly acts as a warning for locksmiths and doesn’t pledge that the key won’t be replicated. To come to one’s rescue, today’s advanced technology empowers users to develop house keys that are impossible to be duplicated.
