Abstract
A lock cylinder of a motor vehicle has a cylinder housing formed from plastic and the cylinder housing has an opening for receiving a cylinder core. The plastic of the cylindrical housing is reinforced at least in certain regions with aramid fibers. Thus, the cylinder housing is extremely robust and increases the forcing resistance of a door lock equipped therewith.
