What is master keying system?

What is the purpose of a key system?

How do master key systems work?

A master key system references a group of locks, and the keys that operate them, which are related in a hierarchy with one key at the ‘top’, which will fit into a large number of locks; and a large number of keys at the ‘bottom’ which may only fit into one lock. The fewer master key levels, the more secure the system.

How are the keys in a keying system related to each other?

The keys in a keying system relate to each other and to the system as a whole. This relationship restricts keying options and the flexibility of the system design. Keep It Simple The more complicated the design of the keying system, the shorter its usable life. Key a building to perform its function.
