ABSTRACT OF THE DISCLOSURE The rotary locking cylinder has a housing with a longitudinal bore hole in which a rotor is inserted. In the lower region of the bore hole, a groove-shaped recess is worked into the housing, a blocking insert being inserted into this recess. This blocking insert projects into the key groove and prevents the rotor from being turned by force so as to shear off the tumbler pins. When employing unauthorized opening methods, the blocking insert must be held against the repelling force of spring elements in an inactive position, which substantially impedes such unauthorized methods or even renders them impossible.
