1) Turn ignition to OFF.
2) Locate the Data Link Connector, its a black 16 pin connecter that is under the driver's side dash, right where your right knee would be. You have to look up into the dash from below to see it.
3) Ground pin 1 of the Data Link Connector by taking a wire or paper clip and running it from pin 1 to pin 4. Pin 4 is ground so you can just short pin 1 to 4 and it will be grounded. Grounding pin 1 tells the system you are ready to reprogram it.
4) Close all of your doors.
5) Turn the key to ACC then back off. The power door locks will lock/unlock. This is the signal that the system is ready for reprogramming.
6) Push a button on your key fob, doesn't matter which button.
7) If you have 2 key fobs, then press a button on the 2nd fob within 1 minute of pressing a button on the 1st fob. Both must be programmed at the same time. If you only have 1 fob then press a button 2 more times to signal that you only have one.
8) The doors will lock/unlock to signal the codes were received.
9) Remove the jumper wire from the data connector."

as far as I know you have to have the dealership do it cause they have to read the codes in the computer to set the remote
I had the same problem. Google "keyless entry remote 2003 Jeep Grand Cherokee".
I found an Internet site which says how to program the keyless entry remote. But there is an error: this procedure is good for Elantra 2001 to 2003. Elantra 2004 must be programmed by the dealer. http://car.justanswer.com/hyundai/n1kw-program-remote-entry-hyundai-2004
A dealership has to do it for you if it is the original from the dealer. If it is aftermarket, like one from car toys they will have to do it for you. Only the company that installed it will have the codes to program it. I have a 2003 xtreme myself, and i have a dealer keyless entry, but I had car toy's install an alarm with other remote functions, only they can program the newer one.
The Saturn dealership did all three of mine free of charge.
