Abstract: An anti-theft locking system surrounds and immobilizes vehicle steering wheels to immunize vehicles against theft and vandalism. The locking system preferably comprises a rigid, circular pan that surmounts the steering wheel and overlies the steering column. In this manner the vehicle air-bag compartment is protected. The pan has a rigid, peripheral rim that coaxially surrounds and ensconces the steering wheel ring. The steering wheel is thus rendered inaccessible to hack saws or cutting tools that are normally used by thieves to remove conventional steering wheel locks. An elongated locking assembly mounted on top of the pan is activated by a removable, elongated, rod that penetrates the locking assembly to fasten the pan on the steering wheel. The locking assembly is protected on top by a substantially tubular, protective shroud, and the lock bottom is protected by a compartment welded to the pan.
