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. A master key system uses security key blanks that are precisely designed keys which could only be duplicated only from a locksmith who created the system.

Master keys are usually being used by apartment owners where they can open each door of their rented rooms/flats, and each occupant possess their own keys for a specific unit as well. That same key may also open the main door into their building or other common areas. But it cannot open other units unlike master keys.

Master key system is also a complex system as it may involve 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.
