Masker keys are keys that are designed to open different locks even if they are not keyed 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. This key can also be used to open the building's main entry door including other common areas in the apartment. It cannot be used to open another unit.
