A master key is a main key that is made to access a number of different locks that are not keyed the same. Master keys are commonly used in commercial setups where the master key holder may have a key to their office's main door that can also open the bathroom, or a maintenance staff may have a master key that opens every door in the same building.

Master keys are usually utilized by property owners throughout apartment buildings in which there is a master key that can open a door in every apartment, where renters also have their keys for their particular apartment. Tenants' key may also be used to access the main door of the building along with other areas accessible to renters. However, it does not have the ability to access all doors in the entire apartment, unlike master keys.

Master key systems also involve grand master and sub-master keys. You need master keys systems if you're not into bringing too many keys when opening multiple doors.
