Remote fob programming

Hello,
I bough a 2003 Grand Prix without remote fobs, I purchased a set on ebay, the programming instructions it came with do not work, does anyone know how to programm them?
Thank you.

when i programed mine, you need to have all of them with you, you enter program mode how the instruction manual says, the on each FOb, one at a time hold the lock and unlock buttons for 25 seconds,

when i did mine i took more like 50 seconds, but the car will beep from over by the drivers side.

Some grand prix's like base model SE's may not have the radio reciever for the fob

Thank you,
I have SE and you are absolutely right it does not have Radio receiver option.
