A master key system is a very important locksmith tool. By properly utilizing this keying technique a professional locksmith can key a commercial building or a house in such a way that one owner manager can open all the doors with his key while at the same time isolating other areas to work on only certain specific keys.  For example, lets say there is a managers office and only the manager should have access to this room, but the manager doesn’t want to carry multiple keys, by simply keying the managers office to open only with the master key this can be accomplished. In addition, there may be other doors in the building that employees should be able to access, such as exterior entry doors or individual offices etc., these doors can be keyed to both the master key as well, as what is referred to, as a change key.  Anyone with one of the change keys can only open the doors that were keyed specifically to that key.Notice the master key was still part of the equation when keying the other doors thus the master key which the manager has a his only key now opens everything.

The system described here is a two tier master key system, additional levels can be added if needed. For instance, maybe a assistant manager needs access beyond just the entry doors but is not permitted in the managers office. By using a three tier master key system the managers office can remain off limits to everyone but the manager while still affording the assistant manager access to all the other necessary doors.

Master key systems can be set up to accommodate future business expansion. It may be the case that there are currently only four doors that need to incorporate the master key but down the road as the business grows there may be hundreds, if properly structured a master key system can grow with your business. This is convenient because it prevents the whole system from having to be done all over as time progresses.

If a master key system seems like it may benefit you or your business please contact a qualified commercial locksmith to assist with further clarification and setup.
