Keyed Alike

Keyed alike means that locks in a set or ‘suite’ have the same key code, ie, any key fits any lock. This is convenient where a large number of locks are to be used by the same group of people or person but can be a problem if individual security is important.  

Keyed Different

This means that all locks have different key combinations, ie, a key from one lock will not fit any other lock in the same group, there is usually a limit to the total number of differs available for a particular lock group but is generally high and not normally a problem for most applications.

Master Keyed

A suite of locks where one ‘master’ key can open all the locks in a suite, which are themselves made to different key combinations. Master key can also open a suite of keyed alike and keyed different in the same suite.
