The ignition lock cylinder is located inside the assembly or lock body that is often welded onto the steering column. Most of the time, when a problem occurs within the ignition system, it will be caused by a fault within the ignition lock cylinder.
Inside the lock cylinder is a series of tumblers where the key is inserted. There is an electrical attachment and a series of wires that run from the cylinder base to a series of relay switches that supplies power to multiple components. Some of the common symptoms of a damaged or broken ignition lock cylinder include the vehicle not starting or power not supplied to the vehicle when the ignition is turned.
Ignition switches are mostly made of metal. Metal can wear down over time. Heavy use or something as simple as a heavy key chain can shift or strip the tumblers, creating damage that only a qualified auto locksmith can repair quickly and affordably. You don’t want to get locked out of your car on top of having a broken ignition switch or broken car key.
