Q: Anti-theft keeping car from starting

asked by on

My security light is on and my car won't start.

The ignition switch in your vehicle has likely went inoperative. Replacement involves a tear down of the steering column and grinding the switch bolts. Afterwards, a 30 minute key re-learn procedure is required. If you need assistance with this, a certified mechanic, such as one from YourMechanic, can come to your home or office to diagnose and replace your ignition switch if necessary.
