Bill, I had this problem with chev suburban, easy free fix for me was:
Turn ignition to Accessory mode (electronics on), Remove NEGATIVE terminal from battery for 2 minutes ( causes car computer to reset and forget the 'key' it expects in the ignition) Hook battery back up. start car.
It's reasonably safe and free and fast, and it worked for me after the Chevy dealer failed to fix the problem in two days of troubleshooting.
The now keep a CARCHIP from Davis, it allows me to reset the computer without doing the battery thing. Sadly, the car hasn't failed in two years since I did the battery thing.
Let me know if it works for you!
Tom

Try to start car, when it quits leave key in run position for 10 mins or until sec. light quits flashing, then turn key off for 10 secs. repeat first step again when light quits flashing turn key off again for 10 secs. then repeat one more time, after 3rd time car should start and run. This is called the password relearn procedure.
