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. Locks are safer because the restricted key-way decreases the possibility of accidental opening using the incorrect key.

Master keys are often used by apartment proprietors where by they are able to obtain access to each doorway of these rented rooms/flats, and on the other hand, each tenant also have a key to their own and specific unit. Tenants's key may also be used to access the main door of the building along with other areas accessible to renters. However, it cannot be used to open another apartment unlike master keys.
