Buick Roadmaster Keyless Entry

It's so easy you'll think something is wrong. Open the hatch. Grab the "D" pillar interior trim cover on the driver's side about in the middle between the top and bottom. Peel it back away from the window seal, like you were prying it off, just enough to peek in underneath it. You'll see some wires and a two pin connector that isn't hooked up to anything. Ground together the two pins of that connector (you can use a female spade connector which works perfectly) and you'll see and hear all the locks cycle. Leaving the pins grounded, then hit any of the buttons on the key fob. The locks will all cycle again. Remove the shorting device from the plug and bingo, you are programmed. "Rinse and Repeat" the process if you have another fob.
