So Mom purchased for me a used Pontiac G6 GT Sedan 4D (at least that's what the sale sign said, and google seems to confirm it's in the ballpark), and both of the keyfobs are malfunctioning; neither of their "unlock" buttons work (the "lock" buttons do though). I was cool with having to use the key to unlock the door until I quickly learned that unlocking it that way caused the car alarm to go nuts and not shut up until the car was started. The previous owner claims this never happened to her and that I might have hit some sort of switch, but I get the feeling that she's not being totally honest and that this is one of two reasons it was such a cheap price even for a used car(Asking price was $2,800, and she took my mom's offer of $2,500; the other reason was that it has 170k miles on it). My short-term search for a dealership that could replace or repair them ended in failure, and I gave up hope on that search when I found the wikipedia page for Pontiac and it said it was completely defunct and has been since 2010. Are there any other dealerships that could deal with the keyfobs? Because the alarm is gonna get very annoying very fast.
