what do you mean "falls down"? is it an electrical pull down, or like a broken mechanism causing the knobs to fall down?
was going to suggest that she drove home, and get somebody to open the trunk from the outside, force the allen key in somehow, but then i saw you say that it won't crank. if she's still in there, and you think its electical, i'd get her to jump in the backseat, pull it up, and "push" the wire back into the battery terminal clamp. i have a once/6 month problem where , when im about to start the car (all acc's come on), and i try to start it, it just goes "click". pushing the wire back into the battery terminal fixes it, but i think its an obc/code issue.
