A Master System is a set of locks in which a single key can open just one lock, a group of locks or all the locks. This system is used in particular by places such as apartment buildings. For example, individuals have a key that opens the door lock to their apartment and to the common laundry room. The building owner or superintendent has only one key to open door locks for all the units and areas in the building. The key that opens all the locks is called the master key.
