ABSTRACT:
The safety key has a shank which is provided with a plurality of control surfaces for properly positioning tumblers and has a front end and a rear end. At a front end, the rotor of the associated locking cylinder has at least one further control surface, which interacts with a further control surface arranged at the rear end of the shank. The safety key is backward compatible and is relatively difficult to copy.
