Sounds like the anti- theft system!! You will need to have a new key programmed by a dealer.

Turn the key to "on" and let the light flash. It should stop flashing after about ten to twenty minutes. Once the light is on steady, turn it off, then start the car. I usually put another battery on jumper cables attached to the cars battery so it does not run down and die before the system re-arms.

After you replace the ignition switch turn the key to start the car and release leave the key were it stops after trying to start wait 10 minutes until security light goes out turn key to full off position then repeat the above procedure two more times for a total of three on the 3rd attempt to start car wait for light to go out then turn key to full off positoion wait 10 seconds then try to start car body control module should learn new pass code and the car should start.

I have towed several of these with same problem. Sounds like to me it needs to go back in for the ignition switch again. Unless it's not going into park. If it's not going into park it would be a shift linkage issue and needs to be adjusted. Chris J.C. Towing & Recovery
