Ignition Switch Lock Cylinder Replacement

The ignition lock assembly contains two components: a lock cylinder to deter theft and an electrical portion that supplies power to electrical components such as the radio, electric windows, and windshield wipers. The electrical portion of the ignition switch also provides power to the starter motor to start the engine.

The ignition lock is an anti-theft device that prevents a vehicle from being driven unless the ignition key is in the ignition switch. If the ignition key is not in the ignition switch, it 's impossible to turn the steering wheel.

To replace the ignition switch cylinder lock, the trim panels around the steering wheel are removed. Then the tamper-proof hardware that attaches the ignition lock assembly to the steering column is removed. The ignition lock assembly is removed from the steering column, and the lock cylinder is replaced. The new ignition lock is reattached to the steering column, and the trim panels are replaced.
