What Are Key Locks and How Do They Operate?

Key locks are mechanical devices used to secure doors, cabinets, and other access points, operating through a simple key and locking mechanism.

• Pin Tumbler Lock: This is the most common type of key lock, utilizing a series of pins of varying lengths that align when the correct key is inserted. When the key is turned, the pins move to a position that allows the lock cylinder to rotate, thus unlocking the mechanism.
