I have had troubles starting my car. I noticed that the security light sometimes flashes before I try to start it, and that's normally when it won't start up. If i Leave the car alone, without the keys in it, for about fifteen minutes, it will start up again. I have tried "resetting" the PK3 key with the ignition, but it doesn't work.

a common failure is broken wires on the lock cylinder inside the column. a shop can verify this and give you a bid.

hey not sure if you have fix it yet but i know how to fix it. Send me an e-mail at [email protected] and I'll tell you how to fix it yourself for about $20.00 in part from radio shack. I had the same problem on my 2000 deville concours.. Its a website i got the info from and I did it myself and saved over $500.00 dollars cuz the dealer will charge you an arm and leg.
