ABSTRACT:
The safety key has a shank (6) which is provided with a plurality of control surfaces (7) for properly positioning tumblers and has a front end and a rear end (6a, 6b). At a front end (4a), the rotor (4) of the associated locking cylinder (2) has at least one further control surface (8), which interacts with a further control surface (9) arranged at the rear end (6b) of the shank (5). The safety key is backward compatible and is relatively difficult to copy.
