radio code needed for grand prix GT

I need some info on how to replace a theft lock radio back into my GP GT. i removed it to put in a new stereo, and now i am trading it in for a 99 GTP. dont want to give my new stereo back to dealer. PLEASE HELP:banghead:

We have quite a few old posts but not all work. This is the last known procedure that worked up to a few months ago. Good luck.
