Best bet would be search ebay. Replaced both of mine and bought a couple for friends through eBay. Programming them should be in your owners manual. If you don't have the manual you can download it from Personalized Vehicle Owner Information
Are you sure you have keyless entry? Surefire way to know is if you have a keypad on the drivers door, but I think there are ones without the pad as well. EBay is your best bet, and programming is easy. Put your key in, turn it run and back to off 8 times, ending in run. Your locks will lock and unlock to signal they are in program mode. Hit any key on the remote within 10 seconds and it will program the remote. Repeat within 10 seconds for each remote up to 8 remotes. I might be a little off but I know I'm close. Been a while since I did one.
