A lock apparatus for locking the steering wheel of a vehicle includes an elongate member, a pair of hook members fixedly secured to one end of the elongate member, and a lock assembly pivotally mounted on the elongate member. The lock assembly pivots to a locking position where it cooperates with the hook members to secure the steering wheel of a vehicle between it and the hook members and away from the locking position to release the steering wheel. The opposite end of the elongate member engages the seat, door panel or other portion of the passenger compartment of a vehicle proximate the steering wheel.
