How do you program a key fob on a 1996 Monte Carlo?

there is a connector under the dash that is used for the computer called an OBD 2 connector. It is rectangle in shape, about 1 1/2 inches long. More than likely you will have to unbolt this. When unbolted, find the numbers on the connector. It should be numbered 1-8 on the top and 9-16 on the bottom(nombers are very hard to see.) You will need to jump pin #4 and #8 with a wire or paper clip. Turn the key on. (some GM models you do not have to have the key on.) The locks will cycle automatically. Once the locks cycle, push the unlock and lock buttons on the key fob within 10 seconds and hold until locks cycle again. Once locks cycle, release and fob should be programmed.
