Master Key Lock
Master keying is the power to utilize one main key to open a number of locks that aren't actually keyed exactly 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.
Apartment owners uses master keys to open each door of their rented apartments, and each occupant possess their own keys for a specific unit as well. Other common areas in the apartment can also be opened using this key including the main door of the entire building. However this key is not going to work on the lock of a different unit.
Multiple master, grand master, and sub master keys may be involved in the master key system making it a complex system. If you want to have one key to all different doors, then master key is what you need.
