This answer was rated:

I have a bmw123m series have disconnected battery and closed the boot accidentally. Now unable to open boot even when I try manually with key removed from key fob

turn the key as far as possible, it should open manually


if not, try applying jumper power from under the bonnet and see if the car will power up


if not, you will need to have the car towed so some of the interior can be stripped and power applied directly to the boot release wires
