A master keyed lock is actually a lock that's built to be opened up by specific keys, but could also be opened using a master key. Restricted security key blanks of a master key are patent protected disabling other key manufacturers create duplicates of that design.
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, and at the same time, each occupant also possess a key to their own unit. This particular key may also be used to open the building's main entrance door together with additional common areas within the apartment. 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. Need one key for different rooms? Master keys set up is your way to go.
