With a scan tool, clear any DTCs if needed. History DTCs will self clear after 100 ignition cycles. this should work,the wright fix is to replace the ignition switch,very common problem.

Thanks!

After calling GM and being told to have the car towed to a dealership for installation of a new ignition and key coding (at an approx cost of $500), I tried a method similar to this and it worked.

The key was turned from off to on 3 times, then turned to the on position for 15 minutes. The code reset and I've had no problems since.

I also reduced the weight on my key ring to one key to help keep this from happening again in the future.
