Master keying of lock cylinders is a sophisticated method used to enhance security and streamline access control within buildings or complexes. This system allows multiple locks to be opened by a single master key while individual keys still operate their specific locks. The process involves configuring the internal pin settings of each lock cylinder to accept different keys, creating a versatile and layered security framework.

Sub-Master Key (SMK)
- Controls smaller subsets of locks within the group managed by the master key.
