ABSTRACT:
The invention relates to a cylinder lock including a number of locking discs (4) turnable by means of the key (8) of the lock and separated from each other by intermediate discs (5) and provided with a key opening (6) and with a peripheral notch (7), and a locking bar (3) which, when the lock is in the locking position, prevents turning of the set of discs and force transmission from the key (8). According to the invention the peripheral notches (7) of the locking discs are located so that the locking discs (4) are placeable in the set of discs in either way with regard to their plane, and at least some of the locking discs (4) are formed so that a surface (6a) of the key opening (6) of the locking disc co-operating with the corresponding combination surface of the key (8) is in the axial direction of the set of discs substantially shorter than the length of the part (A) of the key way of the lock corresponding to said locking disc (4) and located asymmetrically with regard to the locking disc (4) in the axial direction in such a way that turning of said locking disc (4) in the set of discs around an axis in the plane of said disc causes the location of the corresponding combination surface (14) of the key (8) on the key blade to be changed.
