Restricted Keys
The Kaba provides 269 thousand billion more keying combinations than conventional 6 pin cylinders, whilst giving superior security too. There is protection against picking, racking, manipulation and impressing, while each key is registered and supplied for against authorised signatures only. Binary Plus adds a new dimension to lock security with a patented side trap action. If the wrong key is used side pins engage with the lock shell and prevent the lock from opening. The Binary Plus key is thicker than most to restrict hand made copies. Distinctive head design, with dealer and key identification stamped into the head, provides added security against unauthorised duplication.
