However do I replace my key for my 2002 Pontiac
grand Prix. I lost mine. It didn't have a chip, it was
just a plain key. I'm trying to sell it but have no key.
If you don't have any keys you may need to have a locksmith replace the locks but I would first take the VIN and your car title to a GM dealer and see if they can make one for you.
