A master key is a main key that is made to access a number of different locks that are not keyed the same. Locks are safer because the restricted keyway decreases the possibility of the 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, wherein each tenant also has their own keys for their specific 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, this key is not going to work on the lock of a different unit.

Master key system is also a complex system as it may involve multiple masters, grand master, and sub-master keys. If you want to have one key to all different doors, then a master key is what you need.
