Abstract
A portable steering column locking apparatus in two pieces for surrounding the steering column of an automotive vehicle and specifically enclosing the ignition switch and the skin of the steering column beneath which the ignition control rod is located. The cylinder operates in a bolt wing and a striker wing part that cannot be pried apart because of housing projections fitting respectively within side recesses in the wings. The locking cylinder has a carbon steel crosspiece deadbolt operating within an internal "F" groove in the bolt wing and therefore cannot be defeated by common tools used to extract cylinder tools. The hinge of the housing pieces is sealed by welding against access.
