The KEYper® Mechanical Key Control & Peg System consists of a key board that holds from 5 to 150 key plugs. Key plugs are individually locked into a numbered port on the board. A tamper-resistant seal secures one or more keys to each key plug. The tamper-resistant seal from the KEYper® Mechanical Key Control cannot be removed unless the wire is cut. Persons authorized to remove keys with the key control system insert their personalized access peg into the port of the desired key location, and turn to release the keys.
