A master key is a main key that is made to access a number of different locks that are not keyed the same. Master keys are commonly used in commercial setups where the master key holder may have a key to their office's main door that can also open the bathroom, or a maintenance staff may have a master key that opens every door in the same building.

Master keys are also used by landlords or landladies in apartment complexes where they have a master key that could open a door in each flat, where renters also have their keys for their particular apartment. That same key may also open the main door into their building or other common areas. Unlike Master keys, a tenant's specific key will not work on the lock of a different apartment unit.

Complex master key systems involve multiple master, grand master and sub master keys. You need a master key if you do not want to keep a lot of keys for a lot of doors.
