Master Key System

A master key enables two or more different keys to operate one lock according to a structured hierarchy. For example, as an employer you want access control to an office building with ten rooms, one of which is your office, and another your personal storage room. You do not want your employees  to access these two rooms but the cleaning staff must have access to the office. To allow yourself access to all rooms you would carry the master key, your employees would have a change key that allows them access to the other offices and the cleaning staff would utilize another change key that gives them access to all rooms but your personal storage room.  Even if you only have a few locks, master keying can work for you.
