An invention so simple sometimes it defies explanation in terms of its usefulness. Incomparable to anything else.

The KeyController is our stand-alone product that protects all kinds of keys. It takes the concept of key control and broadens it from physical security to IT (Information Technology). By itself, it is the only portable form of key control that can also be fixed to a surface or be passed from person to person without breaching the security of the key or contents. It is excellent for physical oversight of individual master keys in residential buildings and institutions.
