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.
