I have a battery brain and have tried disconnecting the battery multiple times with no luck. I can try manually disconnecting the negative cable and see if it works (can this be done from under the hood as well?)

Once its reconnected see if the inner or outer door handle works.
Its possible that may do it. I never tried that but the way bmw's handle wrecks it may work. The positive explosive bolt kills power from certain parts of the car in a wreck and its supposed to unlock the double lock from what I remember.
Again its worth a shot before going at the door panel with the door closed.
