A PROGRAMMABLE CYLINDER LOCK HAVING A DEVICE FOR PROTECTION OF THE CODIFICATION, AND THE KEYS FOR THE OPERATION THEREOF
A programmable cylinder lock comprising a stator (1 ) and a cylindrical rotor (2), mounted inside stator (1 ) for rotation around its own axis and having a keyhole for insertion of a key (3), and comprising inside rotor (1 ) a number of key followers (5) movable along the longitudinal and transversal directions, intended to cooperate with a key inserted into the keyhole of rotor (2), and locking pins (6) movable along the longitudinal direction, the key followers (5) and locking pins (6) forming together a number of pairs and having toothings intended to mutually cooperate in order to define the lock codification, rotor (2) including a stop bar (9) cooperating with a longitudinal groove (10) of stator (1 ) and susceptible of cooperating with the locking pins (6) in order to immobilize them, and comprising a change bar (1 1 ) which is slidingly coupled with the key followers (5) in order to normally keeping the key followers (5) engaged with the locking pins (6) and to disengage them from the locking pins (6) when said change bar (1 1 ) provides a lock programming position, characterized in that the key followers (5) have a projection (7) which engages a side surface of the key and, at the contact of a normal use key (12), prevents the transversal displacement of the key follower (5) and the change bar (1 1 ), and therefore the disengagement of the key followers (5) from the locking pins (6), whereas said projection (7), at the contact of a special change key (14), allows the transversal displacement of the key follower (5) and the change bar (1 1 ), and therefore the disengagement of all key followers (5) from the locking pins (6) of the lock.
