It will fail if either the outside patch cable is still pulling on it or the door lock actuator is failed in "double locked" mode.

Find my DLA awr-fix thread I have videos that show exactly how the DLA operates and how to manually override the double lock.

(Won't be easy getting in with the door shut: challenging to remove the door card).

You can remove the lock cylinder from the outside if you think the DLA will function from the key input by bypassing the broken cylinder and that's what I would try.

PM for the "how to break into any eXX BMW" directions. (I really don't want to post out in the wild).
