How a Key Opens a Lock

The proper key lifts each pin pair until the gap between the key pin and the driver pin reaches the sheer line. When all the pins are in this position, the plug can rotate and the lock can be opened. An incorrect key will leave some of the pins protruding between the hull and the plug, and these pins will prevent the plug from rotating.  Our courses will go into detail on how this all words.  We also teach you how to effectively pick a lock which is a skill you must have to be a successful locksmith.
