Patented high-precision undercut (branch groove) for better protection against illegal key duplication.
The keys are designed with an undercut profile groove. This is called a branch groove and can only be produced using special machines and a complex milling process. An optional active element in the lock cylinder checks whether this branch groove is present and blocks the barrel if an attempt has been made to use an illegal duplicate key.
