Master Keyed Systems

  • Effective Key Control is essential to the success of any high security lock system. At Calvert Safe & Lock we supply Master Keyed Systems where each lock has its own individual key which cannot operate any other locks in the system, but where all locks can be operated by one master key. This places the security control of a building or group of buildings under the jurisdiction of designated individuals in charge.

    Our Master Keyed Systems enable facilities to access dead bolts, mortise locks, pad locks and even electronic access control systems, further reducing the number of keys to be tracked.
