Welcome to 2CarPros.

Have you tried a different key? If nothing is working, the tumbler may have gone bad and need replaced. Have you tried to see if a small amount of lubricant helps?

If nothing is helping, you will need to remove the tumbler and see what is happening. Most likely, the tumblers in the lock assembly have worn out or broken.

Here are the directions for replacement. The attached pics correlate with the directions. I'm not 100% sure, but the new key may require programming. There is nothing listed in the manual, but I swear it was required.

Installation Procedure

Important: The gears between the ignition switch and the lock cylinder housing must be in the correct position. Failure to do so will cause a misalignment of the gears in the ignition switch and the lock cylinder housing, which may result in a NO START or BATTERY DRAIN.

1. Use a screwdriver in order to rotate the lock cylinder housing gear clockwise to the START position.
2. Remove the screwdriver and allow the lock cylinder housing gear to spring return to the RUN position.

5. Install the steering column trim covers. Refer to Steering Column Trim Cover Replacement.
6. Install the knee bolster.
