Abstract
A lock cylinder with key, in which the cylinder has a rotor and a stator with radial tumbler pins and the key has depressions corresponding to the tumbler pins. At least one tumbler pin functions as a control pin (K), in that a zone produced by an offset provides a side coding (F) in addition to the depth coding (T) with a diameter corresponding to an additional coding (B) and the associated key has a depression with sides (8), whose spacing between the sides corresponds to the coded diameter (B) of the control pin offset and whose tumbler pin cooperates on the one hand with the milled coding in the key and on the other hand with control faces formed in the key blank. The aim is to create a copying or forging obstacle by means of a technical measure in the cylinder and on the blank.
