key

Hey guys, I'm having issues programming a new key fob for my 95 tahoe 2 door and need your help please. I am positive I have the correct fob and belive I have the correct procedure but am suspecting wiring issues. I have tried bridging the G and A terminals on the OBD port under the dash...

So I just got a new wheel lock set, after having my lock key stolen and the wheels being taken off. They left the old lock nuts, but kept the key. My new set is the SAME EXACT set as my old one.. it fits the old lock nuts and the new ones.. how is this even possible?? Aren't they supposed to...
