Master key or master keying is the capability to use one "Master" key to open one or more locks that are not actually 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 also used by landlords or landladies in apartment complexes where they have a master key that could open a door in each flat, and at the same time, each occupant also possess a key to their own unit. That very same key may additionally open the main door to their building or any other common areas. However, it cannot be used to open another apartment unlike master keys.

Complex master key systems involve multiple master, grand master and sub master keys. Master key is all you need if you must have an access to multiple doors without the hassle of asking each key holder to unlock the door for you.
