A programmable cylinder lock of the type comprising a stator (1) and a cylindrical rotor (2), mounted inside the 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 (4) movable along their own longitudinal and transversal directions, intended to cooperate with a key (3) inserted into the keyhole of rotor (2), and a number of locking pins (6) movable along their own longitudinal direction, the key followers (4) and locking pins (6) forming together a number of pairs and having toothings intended to cooperate in order to define the lock codification, the rotor (2) including a stop bar (9) cooperating with a longitudinal groove (10) of stator (1) and having projections susceptible of cooperating with notches of the locking pins (6) in order to immobilize the locking pins (6) when the stop bar (9) engages the locking pins (6), and comprising a change bar (11) which is sliding-ly coupled with the key followers (4) in order to normally keeping the key followers (4) engaged with the locking pins (6) and to disengage the key followers (4) from the locking pins (6) when the change bar (11) provides a lock programming position, characterized in that one of the members (4, 6) which compose a pair is provided with two parallel and adjacent toothings (7a, 7b), each toothing (7a, 7b) having its pitch phase displaced with respect to the pitch phase of the other toothing (7b, 7a), and in that at least one of the members (4, 6), which compose the pair has a limited mobility along the direction of the axis of rotor (2). |
