    Turn the key farther than normal. With no power

    you have to turn the mechanical stuff instead of just activating the switch.

    That didn't work. Not sure why but you are correct, it is suppose to. I called the dealer and here's what they recommended and what I did - in case anyone else gets in this jam. I used a battery charger to do this:

    1) pop the license plate light out
    2) attached the hot end to the light socket
    3) attached ground to frame (I had to attached it to the exhaust tailpipe)
    4) use remote key to open

    Now I am charging the battery.

    You turn hard enough or in the wrong direction (m)

    You can also unlock the trunk manually with the key by turning it hard too, then you can connect the charger directly to the battery.
    Look at your manual for all the above info when you get it open.

    Griffs-can U let us know if charging the battery(m

    thru the license plate lamp really works? The + wire from that light goes to the LCM, not the battery, so it might not work. The other concern is that wire is so thin it could burn up if it were to carry all the current a battery charger would be trying to charge the battery with. Hope back feeding power to the LCM doesn't have any adverse effects on it.
    If it doesn't work, and you can't get a door or trunk open with your key, you can always jack up the RF corner and connect the charger to the starter, that is a direct connection to the battery.
    Let us know how you make out.

    Re: Griffs-can U let us know if charging the battery(m

    It did work and the battery had been dead for 6 weeks. I popped the license plate socket out and connected the charger to it. I had the charger setting on 12V/6amp and only needed enough power to get the remote to unlock the door (dealer said it is servo activated and that's how their technician would do it). It was a split second before it opened. So it was not the full load of a jump. I had the hot connected to the socket and the ground to the tailpipe. Originally I tried to find a place on the frame but it didn't work. Then tried the tailpipe of all places.

    Just to show you how skeptical I was of the entire process - my wife suggested the same thing to me before I called the dealer. I looked at her like she was crazy. I then called the dealer and he told me the above procedure. When she asked "what did they say", I had to say "what you said". So I tried it....had no other choice...the key would not open the door and my trunk lock doesn't work (it is broken).

    Once I had the door open I charged through the engine compartment.

    Griffs,

    Congrats that it worked!

    I hate to be a duncehead here, but can you tell me exactly what I have got to do (for future reference) if the same thing ever happens on mine? As they will tell you on this board, electrical stuff and me don't exactly click real well (have an innate fear of anything electrical, think I must have been electro shocked in a former life, lol, or something)

    I know, if possible, could you take a few minutes and do a mini DIY writeup for this board and post it in your thread? Like, here's the symptom I had, and then here's the steps to follow to solve it (1,2,3,4 etc).

    Thanks!

    Eurodavid

    Euro, make sure your mechanical locks work and (m

    you won't need to do what Griffs did. However, pop the light out by putting a screwdriver in the slot on the left side of the light frame and push it to the right while you pry the left edge down. With the left side down about 1/4" move the light back to the left and drop the right side down, then the light will come out.
    Once out you will see the 2 wires and the metal strips that go to the bulb. The brown wire is ground, so you want to connect the charger + to the other connection, and then connect the charger - to the tail pipe. That's it.
    FYI, if you have never taken the lights out before they could be a royal PITA to get them to slide enough to the right to get them out.
    Be careful the screwdriver doesn't slip and scratch the paint.

    Euro, 12 volts will never hurt you unless you clip the charger leads to your tongue.

    Reminds me of an old story:

    Q: What is the definition of an insomniac-dyslexic-agnostic?

    A: Someone who lays awake at night wondering if there really is a Dog.
