UPDATE but not really, kinda latteral movement. got the 556u for $20 from my friend who knows a CC installer, tried it out last night it worked, just that i didnt have the right torx socket to off the top of the steering wheel shround and it was like 25 out so we stopped pulling the door panel off so we wouldnt crack it, my garage isnt heated. so next weekend i am taking it out to the garage where it is heated and we are gonna get it done plus thats where the good tools are. if anyone knows how to pull the drivers door panel off on a 03 deville it would be much appreciated, we got half of it off, the screw out at the top behind the handle, but it is hung up in the center area and cant figure that whole connection out(has a wiring harness on it) and it was cold so we stopped before we broke the panel, but it is starting with the 556u when we put the ring around the key cylinder, just need that socket to finish it.and no its not going to a shop to get finished we are now pissed off and gonna figure this out.
