Same situation with my 06 GP. 1 key and 1 remote when I bought it. Every site I researched said I couldn't program it myself. None of the info I got from these guys here worked either. Bought a keyfob off Craigslist and took it to the locksmith. $35 later, I'm a locking/unlocking, trunk poppin', remote starting MOFO. Not sure how much the dealership wants but call around to all the locksmiths in your area. I got prices from 35 to 90 bucks. Have all keys and remotes ready to go and only pay once. Good luck.
