Master Key Lock
Master key or master keying is the capability to use one "Master" key to open one or more locks that are not actually keyed the same. Locks are safer because the restricted key-way decreases the possibility of accidental opening using the incorrect key.
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. However, it cannot be used to open another apartment unlike master keys.
