Master keying is the power to utilize one main key to open a number of locks that aren't actually keyed exactly the same. A master key system uses security key blanks that are precisely designed keys which could only be duplicated only from a locksmith who created the system.

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, then occupants have their keys for their unit being rented. Other common areas in the apartment can also be opened using this key including the main door of the entire building. Unlike Master keys, a tenant's specific key will not work on the lock of a different apartment unit.

Multiple master keys, grand master, and sub master keys may be involved in the master key system making it a complex system. Master key system is all you need when you want to possess only one key to access all doors in your home or commercial building.
