Abstract (en)
The invention relates to a locking system of a cylinder lock and a shank of a key with at least one disc tumbler (3) with a central opening (20a) to receive the shank (5) of the key. The tumbler (3) is rotatable about the longitudinal axis (O) and is provided with at least one coding projection (2000) and with at least one coding cut-out (30) for a latch (40). The shank (5) is formed by a longitudinal plate-shaped body with at least one coding surface (50) to interact with a coding projection (2000) for rotation of the tumbler (3). At least one coding surface (50) is formed by a coding surface (50a) displaced in the direction (T) of the width of the shank (5) at a distance (ΔT<sub>5</sub>) from the edge surface (523) of the shank (5) and the at least one coding cut-out (30) is formed by a coding cut-out (30a) shifted by an angle (Δα<sub>3</sub>) relative to the position for cooperation with the coding surface (50) on the edge surface (523) of the shank (5).The invention also relates to a cylinder lock with this locking system and a key for this locking system and this cylinder lock.
