Seams that the answer to this unfortunate incident, according to the dealership is to "break a glass of choice" to access the hood release handle; which is the only thing that does not go into "deadbolt lockout" which prevents pulling any and all lock linkages. Once inside your hood, you can jump your battery from the battery positive point and negative tower screw affixed to the strut tower top cover. I was then informed that one has to install and exterior weatherproof cigarette lighter socket in a hidden area, as so that you may regain access if the incident should ever re-occur !!
I would use the key to unlock the door.
A BETTER WAY: Insert key in door. Lift handle all way up. Turn key all the way forward, past horizontal. (Resistance may be felt at horizontal, but apply reasonable torque without twisting key off.) Door should now open. If this does not work, open trunk, remove trunk light lens, run 12 volts to bulb socket, red to positive and other wire to neg. This runs power to car electrical system because trunk light circuit opens when trunk lid is raised. Don't confuse license plate light, which is also in the trunk lid, for trunk light. There is no open circuit to license light with light switch off.

You can also insert the key into the trunk key slot and manually open the trunk, even when the battery is dead. Then you can replace the battery, everything else works.
turn the key to unlock position, lift handle, and turn the key some more. you will feel mechanical resistance making the key simi hard to turn.
IF YOUR BATTERY IS DEAD THEN THE DOORS WILL NOT UNLOCK WITH THE KEY NORMAL......ON A '93 740I YOU CAN PULL UP THE PASSENGER HANDLE AND TURN THE KEY ALL THE WAY TO THE LEFT OR RIGHT ....(CANT REMEMBER WHICH WAY) BUT THIS WILL UNLOCK THE DOOR
By using your key to unlock the door.
use key to manually unlock. manual unlock will not work.
Stick the key in the door lock and turn.
Use your key manuel like the old days. Kurt
BMW's have auto-locks a little different from other cars, if your battery is dead, the doors won't open. To change the battery, you need to open the trunk, this is where the battery is located. You will see a panel with some screws, you need to remove that and underneath is the battery.
Remove the rear seat.
If you have the cars original key, and it has a good battery in it, just press the remote button. Other than that, I may suggest you call the dealer. --------------- Have you tried just inserting the key in the driver side door and turning it? That's how you open the door with a key when the key battery is dead.
In the trunk. Right hand side under sidewall flap.
open the trunk , right hand side console . BATTERY WEIGHT 67 POUNDS.
if the car is unlock you should be able to push the right-side of the gas cover or otherwise there is a manual pull handle inside the trunk located above the battery.
