Master Key Systems

A Master Key system is a series of keys that are different from one another. These keys have the capability to specifically open one lock, a group of locks, or all the locks in a specific environment. A "Master Key" has the capability to override all the locks of the system. In other words you can have hundreds of locks that all have a different key and still have one key that overrides all those locks.
