<p>A lock cylinder comprises a cylinder body wherein a cylinder plug (1) comprising a clot (2) for the key (18) of the lock is rotatably arranged. The profile of the key slot and therefore also of the key is determined by profile forming elements in the form of rotation bodies (6,7) which are inserted in bores (4,5) extending through the cylinder plug (1) parallel to and adjacent to the middle plane (10) of the key slot (2). The profile elements (6,7) may be made of hardenable steel, for instance by turning, and may comprise a number of portions of different diameter so that the total number of key profiles obtainable becomes high while permitting the key profile to be made very thin and correspondingly difficult to copy. <IMAGE></p> |
