The master key system is an efficient and money saving blueprint to maintain the security and key control of large buildings or facilities. The purpose of the master key blueprint is to allow and restrict access to areas in the building. The master key references a group of locks, and the complimentary keys, organized in a hierarchical way that allows master keys to open all the locks and the bottom keys to open certain locks. The less master keys that are in the blue print will allow for stronger security. This master key system blueprint is able to be adjusted with little changes to the existing locks. Our professional team can assist you with all your master key installation at very affordable prices.
