Master keying refers to a mechanical locking system used throughout a building whereby one key can access multiple locks. This system, also known as a master key system (in reference to the master key which accesses all locks), is used to provide or limit access to different locked areas within a building or complex.
A master key is a key that opens several different locks, related in some way, within a master key system. For example, an elementary school may have a master key which will open all classroom doors. Classroom doors would each also be opened by a key which would only open that one classroom door.
A master key is a key that opens all of the locks in one building or apartment complex. For example, think about a school. Each classroom has its own lock, yet a custodian only has one key that opens every door to every classroom, gym, and cafeteria. This one key is called the master key.
For example, a Facility Manager may have a master key that can open all doors at their location while employees have sub-master keys that only open a single door or limited doors depending on their need for access.
