Abstract: A steering column lock comprises a bearing-mounted, free-rotating keyhole cover that covers an underlying locking device. When installed on the steering column of a vehicle, the steering column lock prevents a would-be car thief from grabbing the lock with pliers or another tool and using the lock to turn the steering column and thus drive the vehicle, because rotation of the free-rotating outer cover does not cause rotation of the other portions of the lock.
