Rekey Locks & Masterkey Systems

Keying is a term that describes the arrangement of the keys in a building, assigning them into groups in order to limit the doors that personnel will be allowed to operate by key. It is important to understand that the purpose of a masterkey system is convenience. It would be cumbersome for an owner to carry a key for all the locks in a building or group of buildings. Masterkeys must be carefully controlled as their loss could require all of the locks to be rekeyed.

There is a common misconception that a masterkey system implies greater security. However, the highest degree of security can only be found in a cylinder that is operated by its key and no other. Therefore, the more complex the key system becomes the less security it provides.
