Master Key Systems
Master Key systems are one of the most commonly used security systems in commercial buildings. In a simple explanation, a master key system allows a person with a designated key to get access to a specific place along with the owner of a master key which can also be used to unlock the same place. Whether you are using an electronic or mechanical master key system in your office or commercial building, lock issues are rampant if maintenance is not done properly.
