The warded lock’s basic design was created by the ancient Romans. The basic principle behind its operation is a series of “wards” (projecting obstructions) that prevent all but the proper cut key from being rotated inside the lock. These obstructions have been placed in the path of the turning of the bit portion of the key.
The number of wards in the lock can vary, but normally two is the minimum.
These locks offer only token security to the user. Besides being easy to circumvent, the warded locks offers only about fifty alternate keying combinations. Picking them is generally regarded as trivial.
In this article, you will gain insight about various mechanisms and ways to pick the warded lock.
