Master Key Lock
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. 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 being used by apartment owners where they can open each door of their rented rooms/flats, and on the other hand, each tenant also have a key to their own and specific unit. Other common areas in the apartment can also be opened using this key including the main door of the entire building. But it cannot open other units unlike master keys.
Master key systems also involve grand master and sub master keys. If you want to have one key to all different doors, then master key is what you need.
