A Master Key is a key system where selected keys can open a number of doors allowing different groups of people have access to all or specifically designated areas in a building.
This system is very common in large organizations where different levels of access are needed for different people.
At the core of a master key system is the concept of key hierarchy. The highest level key is called Master Key and it opens all the doors within the building.
Right below it there are sub master keys which can open a subset of doors and then there are individual keys which can only open specific doors.
This setup allows a secure access control which reduce the number of keys an owner needs to carry.
