ABSTRACT:
A reprogrammable lock comprises a rotor (2) mounted rotatably inside a stator (1). In the rotor (2) are mounted key reading plates (3) to read the coding profile (8b,9b) of a user/programming key (8, 9), locking plates (4) that can couple with the key reading plates (3) and are adapted to block rotation of the rotor (2) with respect to the stator (1), two lateral inserts (6) integral with the locking plates (4) and provided with an arched surface (6b) adapted to slide on the inner surface of the stator (1), and a rotation stopping plate (10) free from the locking plates (4) to block rotation of the rotor (2) with respect to the stator (1).
