    (54) Cylinder lock


    (57) Lock cylinder for fastening in a lock, which lock cylinder can be released only by means of an associated key and an auxiliary tool which controls an arresting member into a release position. The arresting member (33) can be displaced by turning the cylinder core (24) into its locking position and is blocked in the key removal position by the cylinder core (24) against return displacement into the release position.
    Assembly and disassembly thus require the use of the correct key.
