Abstract
The locking cylinder has a stator and a rotor, which can rotate in the stator and has a key opening into which a key can be inserted. The locking cylinder has a multiplicity of tumbler-mating-tumbler pairs, wherein each of the tumblers has a first part and a second part that are connected to one another, for example, with a press fit. In the method for programming a locking cylinder, the locking cylinder has at least one two-part tumbler, having parts that are connected to one another with a press fit. In the method, when a key is introduced into the key opening a length, effective in terms of locking, of the tumbler is changed by the first part and the second part sliding one into the other or moving apart from one another, in particular is reduced by them sliding one into the other.
