Hey guys recently picked up a super nice 99 yukon denali and it didnt come with a key fob. I bought a fob and tried the #4 to #8 pin trick but my #8 has no metal. So i tried to use the other method where you get in, put in the key while holding unlock and cycle the key. After cycling the key and releasingthe unlock button my truck does nothing. I searched and saw a thread that said do the second procedure after pulling the radio fuse. I tried that and still nothing. The truck has an aftermarket radio. What other option is there to get this fob to work? Any help is greatly appreciated.
