This training kit will help you learn how to repin master and sub-master key groupings. Master keying is used everywhere to both allow and control access of personnel and guests to a facility. The kit contains all the keys, pins and a cheat sheet to repin our set of progressive locks. When the master pinning is completed you will have three groups of keys.
Keys are identified by playing card markings.
Master key will open all four locks.
Sub master keys will open two of the locks.
Standard Key will only open one lock.
The repinning is pretty simple and only involves changing the BOTTOM PINS.
