    reach up inside the grill from the bottom and pop the hood latch.. Ive had to do this a LOT of times with new GM trucks when i was driving a wrecker. Then you jump the truck off so you can hit the keyless or at least turn the key... Then jump the truck off and find out why the battery went dead.

    X2 what Murdog said, even though it might be difficult for you.

    Option 2.. If you can't access your hood latch to gain access to charge your battery, you can charge your battery through your trailer wireing B+ lead IF you remember which one it is, & then hook your chargers ground clamp to a clean chassis ground.

    All this techno stuff is convienent & really great, untill Onstar tells you "sorry" we can't help you with this particular problem & then it just becomes a P.I.A. & the difficulty factor far outweighs the convienence. ha ha ha

    This is one reason you should put a tag wire on your hood latch so it can easily be hooked with a screwdriver, another piece of wire, or even a stick found alongside the road, not only because of remote/power door locks, & a dead battery, but because hood release cables tend to break at the most inopprotune times. Make it only long enough that you can barely reach it with your tool of choice. This will leave it far enough back in there & well hidden, so that auto & battery thieves won't see it.

    OK, what if i put positive to the 12+ of the the trailer hitch and negative to the chasis, will it give me a chance to unlock the doors that way?

    It depends on the amprege output of your battery charger & just how dead your battery really is, as far as whether it will do it immediately. Be patient as it may take 10-20 minutes for it to build the battery up far enough to actuate them.
