Your door is what is known as 'dead locked'. There is a small servo motor which controls each door lock. When these motors go they lock up and make it impossible to open the door. Here is the procedure. This is for a rear door but the process is virtually the same for a front door.

open doors ,, remove batt cable for 2-3 mins (with doors open) Hook batt cable back up unlock doors with switch (while still open ..shut doors try key first lock then unlock !!
Should do it !!!

A competent locksmith can solve this problem easily.

Try to hook up a battery charger to the battery post of the starter to CHARGE the battery enough to open the doors.

Get a new lock as the dead lock has broken. But befor you have it installed have the key tumblers for the dead lock

I have the same problem - Drivers door windows wing mirrors and drivers door lock not working also air bag light on. The car has been to a BMW specialist for over a week as the drivers door dead locked.
The mechanic used his diagnostic gadget which showed a problem with the drivers door. All other doors windows locks work except drivers door. Has check the power supply to the drivers door switch all ok. Is the problem with this internal window control switch and how does this affect the drivers door lock?
Please Please help
