Comfort Access Stopped Working all doors.

None of the handles or trunk lid will unlock the vehicle anymore. Or lock it.
Battery in the remote replaced twice.
Can't be certain what happened before it stopped working. Car was in accident and was repaired about 2 weeks prior to it stopping working.

That's all I got. I searched for this problem but haven't seen anything exactly the same.

Only time I've seen this happen the OP's comfort access module was toast and had to be replaced. Do you have a second key ????

As with almost anything that can go wrong with BMW the place to start is with an OBD diagnostic tool. My Foxwell NT510 paid for itself the first time I used it.
