I have a 2002 Pontiac Grand Prix.  According to the dealer, without a working key,  I have to bring it to them so they can marry the new key to the body control module.  So about $100 for towing, $45 for the key, $110 for the keyless transmitter, and who knows how much the service cost to program the key...

Is there any way I can force the programming of the new key myself ??  I really do not want to have the darn car towed 20 miles to the dealer.

Any help would be great!

Matt

anthrax. your vehicle has a theft deterent system that must be reprogramed to the signal (resistance)of the new key (get two).If you have one spare key it is easy to program an other your self.

I know that you can get a key cut to your car off the vin number at the dealer, but I doubt they can program it to your car that way. Don't worry about the keyless remote though, you can get them at the junkyard usually for a lot less and I heard Autozone is now selling aftermarket oem replacement remotes. I have access to the info needed to program a replacement remote, but you're out of luck as far as the key goes. you have to have the dealer program it if you have no valid keys. You don't have a remote starter on this vehicle, do you? if you did, you could use it to trick the car into programming the new key? let me know
