Have you ever seen a maintenance worker with a heavy key ring hanging from a belt? A well-designed master key system reduces the number of keys required when one key opens many doors.Īndy Crestodina, a Chicago apartment building owner, put that thought this way, “You guys did such a great job with the master key system.
#Master key install#
Why would anyone want to install a master key system in their facility? Many reasons, but foremost is increased security related to controlling and restricting access. Master Key Systems reduce the number of keys required in a building, providing convenience as well as security. Usually, many changes are made to the plan, without impacting the final cost, before the locks, cylinders and keys are ordered from the factory. Once this keying plan is approved, key codes are recorded, cylinders keyed, and keys cut.
This schematic is used, much like the blueprint for a building, to communicate how the system will be used. Through the use of time-honored symbols and abbreviations, for example, MK for Master Key and GGM for a Great Grand Master key, a diagram resembling a genealogical family tree or a corporation’s organization chart, is produced to communicate which keys will operate which lock, or set of locks. Any system providing different “access levels” must be tailored to fit the security needs of the specific building (or groups of buildings) where it is installed. Like an architect’s drawing, it translates a vision to both allow and restrict access to property. In this sample MK schematic, all the blue boxes represent master keys, all the lavender boxes represent change keys.Ī master key system schematicis a blueprint for building security.
