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.

Master keys are usually being used by apartment owners where they can open each door of their rented rooms/flats, where renters also have their keys for their particular apartment. That same key may also open the main door into their building or other common areas. It cannot be used to open another unit.

Master key system is also an intricate system as it might require multiple master, grand master, and sub master keys. If you want to have one key to all different doors, then master key is what you need.
