When we're speaking about residential and commercial security and safety needs, keys will almost always be on top of the subject. Restricted security key blanks of a master key are patent protected disabling other key manufacturers create duplicates of that design.

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 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. Unlike Master keys, a tenant's specific key will not work on the lock of a different apartment 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.
