The security reversible key with an assigned cylinder Z has a blocking groove BN with a coded blocking depth (B1, B2, B3), which runs parallel to the axis of the key (x) from the tip of the key to at least the first position (P1) of a row of tumbler pins (A2) on the key. In the assigned cylinder at least at the rearmost coding position (P1) a pair of tumbler pins corresponding to the blocking groove BN with a blocking tumbler pin BZ and an extended blocking counter pin BG are foreseen, whereby the blocking counter pin BG impinges on the cylinder housing (10), if the blocking groove is insufficiently deep and with this the complete insertion of a key with an insufficiently deep blocking groove is blocked by the pair of blocking tumbler pins. Simultaneously the blocking tumbler pin BZ with the counter pin BG at the position (P1) also serves as coding tumbler pin. In the case of the locking system with security reversible keys for locking installations at least two areas are defined, whereby in a first area G1 several additional security elements and a blocking code function and in the second area G2 a more simple basic coding are foreseen. With the first area G1, an unequivocal segmentation into independent market areas (M1, M2, M3) is defined and with this a world-wide unique locking system with enhanced security and applicability is created.
L'invention concerne une clé réversible de sûreté qui est munie d'un cylindre associé (Z) et qui présente une rainure de bloc (BN) ayant une profondeur de bloc codée (B1, B2, B3) qui s'étend, parallèlement à l'axe de clé (x), de la pointe de la clé à au moins une première position (P1) d'une rangée de gorges (A2) sur la clé. Dans le cylindre associé se trouvent, au moins au niveau de la position de codage la plus en arrière (P1), une paire de gorges correspondant à la rainure de bloc (BN) et munie d'une gorge de bloc (BZ) et d'une contre-gorge de bloc allongée (BG), la contre-gorge de bloc (BG) sur la gaine de cylindre (10) se levant lorsque la rainure de bloc n'est pas assez profonde et que donc l'insertion totale d'une clé à rainure de bloc trop peu profonde est bloquée par la paire de gorges de bloc. La gorge de bloc (BZ) sert également de gorge de codage avec la contre-gorge (BG) à la position (P1).
