he has a 1999 Grand Am SE , my car has one of these and this is why i have never tried it on the GTP, if you look on the latch on the trunk lid you should see a yellow tab that you can pull out and it has a lock sign on it, i have always been curious as to what it does but i guess now i know, as how to fix it you may want to call the dealer and ask.as i think he posted it here
