For a while now, cam locks have become quite popular, and more homeowners are opting for them over traditional generic locks. This lock was invented in 1985 by a Canadian, Volker Guelck. The cam lock is made from a metal plate, called a cam, which is attached to the core of the locking mechanism and rotates to lock or unlock the door as the key is turned.
In recent times, the cam lock was modified to include a wheel-based number combination system that made keys obsolete. Instead of turning a key, these locks have numbered wheels that are rotated to form a two or three number combination. Such a lock is called a combi cam lock.
