Master keys grant your facility a high level of effectiveness in terms of safety andsecurity management. Typically, a lock is usually accessible with only one key.
However, a master key can grant access to more than one lock, thus allowing the keyholder to visit multiple areas in a facility freely.


A master key lock system refers to the implementation of a lock system in a facility that adopts the master key for safety and security management. With the master key, the personnel with high-level access does not have to carry a chain of keys at once for the administration. A master key eliminates the inconvenience of carrying many keys and the risk of losing them.
