Steering wheel lock

Hi Gary:

If the tumbler isn't working properly, one of two things is happening. Either the key is worn out (try a different one) or the lock cylinder tumbler is going bad. In that case, you will need to replace the lock assembly.

The only real tricky part is if the key has a sensor which the car has to recognize to start. If it does, you may want to have a shop or locksmith replace and reset the system. It will require some specialized tooling.

Here are the directions for replacement. The attached pictures correlate with the directions.
