Master keying is simply a method of keying multiple locks to a single "master key" while assigning an individual lock to a separate key.  For example: an apartment complex may have a master key that works all the apartments in the complex, but each apartment has its own unique key that works that apartment only. Master keying  allows the owners, management, maintenance personnel etc.. the convenience of carrying only one key.
