    Change the battery - I recall seeing a spot in the owners manual that shows you how to put a new $5 battery in.

    Use the manual key also. It's a watch battery and less than $5 too. Like was said, follow the manual and go slow, or you'll break some small tabs in there.

    Re: FOB Inoperative

    When I bought the thing, meaning the car, they said that if it got weak to key into the car with the metal key then place the fob in a slot in the center arm rest that would help it pick up the signal, but I have no idea if that was true or just smoke they were blowing my way.

    Yep that does work. You can't miss the slot that it fits into. I believe the same slot is used to program a new one also. As far as taking it apart it seems like your going to destroy the thing before it comes a part but just go slow and work your way around it. There is a small indention that you can use to start separating it. If I remember right if your looking at the fob its to the right of the trunk button not easy to see but you'll see it when it's apart. It take a 2032 or 2025 battery I can't remember.

    Since it only needs to be 3' feet away to auto open and start the car, I don't see that. Did you get the message in the DIC?

    I dropped my FOB and it shattered a couple months ago. Looked like a watch battery and computer chip were on the inside. Dealership gave me a new one no cost

    Re: FOB Inoperative

    I have opened the FOBs for both my 2009 CTS-V and 2008 DTS quite a few times for various reasons (broken FOB cases, battery replcement, etc.) with no problems.

    The FOB needs to be within one meter (approx. 33 in. or 3 ft.) of the receiver to automatically unlock (that is why only the side that you are on is unlocked) or start the car. The use of the buttons on the FOB will work at a distance of 30 ft. or more. The receiver for the automatic open or start is located under the console, and that is why the little pocket in the console works well with weak batteries (it places the FOB only a few inches from the receiver). You should get a DIC message for a weak FOB battery, but that is not reliable and I would not depend on it.

    The battery that goes in the FOB is not a watch battery. It is condsiderably larger and is 3 volts rather 1.5 volts.
