My drivers door will not unlock when using the remote or the central lock/unlock button. When I lock the doors with the remote they all lock correctly, but when I try to unlock them they all unlock except the drivers door. I am able to unlock the door by pulling the door handle from the inside but its pain to do so every time I lock my doors. If you guys have any advise on what it might be, I would greatly appreciate it.Thanks for the help,E90 320I 2005 sedan
