Master Keys & Restricted Keys allow for a Single Key to access to multiple locked areas with differing locks.

Most popular in Commercial applications, Master Key and Restricted Key systems are a way to simplify your security and allow customised access control for different areas of your business. Master Keys allow single-key access to multiple locks by rekeying all locks for that access level to fit the same key.

Restricted Master Key Systems serve the same purpose, but with the added security that all keys which are keyed to fit the system are listed and printed with a code , and any locksmith asked to make copies of such a key has to verify the customer with management to ensure employees of the company cannot copy a master key without express authorisation.
