make sure your key is clean try again, if not the system will tell you to wait 3 mins while key is in ignition this will reset the system and dash will tell you to start vehicle, you should be fine after that, common cause dirty key!!!!!!!!

you will need to replace the vats lock cylinder and key. the wires break at the ignition switch. the new cylinder will come with a dummy key . you will need to get a new vats key cut to that blank. take yor old key or vin# to the dealership so they wil know what your vats# is.

I've got a 97 deville d'elegance that has issues similar to these. Last year the red anti-theft light came on and the car wouldn't start-took it to the dealership and they replaced the PCM? (the main brain for the system) for $900...the guy told us the wiring was so corroded he didn't want to mess with it much. Today the message started flashing on the dash that says "anti-theft problem/ car may not restart" but it still turned over in the driveway a couple times so I am hoping I can reset it. The wiring system is jacked and will probably need to replace the wiring harness completely. Doubt its worth it. Not a secure feeling with 2 babies in the back seat in the middle of winter....
