Abstract: A lock inhibitor for a steering column has a flexible cable connected with a manually operated floor mounted transmission control mechanism. The transmission control must be manually moved to the "Park" position before the lock inhibitor can be moved manually to a position which will permit the ignition key to be rotated to the "Lock" position when the key is removed.

Abstract: A vehicle steering column assembly incorporating a steering shaft lock plate assembly mounted between the steering wheel and the stationary upper housing of the column. The lock plate assembly includes a disc-like locking plate of a hard plastic material formed with a series of blind holes therein for receiving the end of a locking bolt. The plate has a central metallic hub which is internally splined which mesh with the splines of the steering shaft. The locking plate construction prevents the unauthorized displacement of the locking bolt and the steering of the vehicle.
