The battery died while the car sat awaiting starter repair. My key won't unlock the doors. AAA guy spent an hour, then a locksmith spent another hour trying to break in to my car. Something about a vacuum system that sucked the locks shut everytime they tried to slimJim 'em. I'm stuck.
If you haven't found this already this is how you open the doors.
A great thing with the Bmw E34/E32 is that it is almost impossible to open the doors without the key. But when your battery dies this feature might get you stuck outside of your car.
Unlocking procedure: ( Procedure courtesy of " the Master" Bill R. )
1. Insert the master key into the front right door.
2. Pull up the door handle.
3. Turn the key counterclockwise to emergency unlock position 1.
4. Open the door.
5. Close doors and turn the right front door lock to the synchronize position 5.
This is for the driver door. The passenger door is the mirror image of the picture

I should have told you the locksmith tried the procedure you describe, and I tried it again just now. No luck. I'm assuming the Emergency Unlock Position is 90 deg counterclockwise from vertical as that is where I felt the key move something inside.
As a last resort, I'm looking at replacing the windshield so I can crawl into the pasenger compartment after the old one has been removed.
Please tell me there is another way--there's nothing wrong with the windshield!

sorry to hear your still locked out. Are you sure you did the trick right?
The factory trick worked for me however if it doesn't for you here's some other tricks.
try Stewart Ebrat's trick taking the truck light bulb out and connecting the positive jumper cable to it. Now the car has power to open it.
Another trick from Mike S: My wife has a 1991 525i. She had a dead battery, and the doors were locked. I did not know about the factory E34 unlock procedure. What I did was open the trunk lid, and take off the trunk light cover and light on the right side. With a voltmeter, I was able to sense enough voltage to tell what polarity each leg of the light was. I then carefully jumper clipped a 12VDC NiCad pack to the light socket, and was able to open the locks with the key (in the drivers door). The front right door in that car is a little screwy, so the normal procedure wouldn't have worked anyway.
I thought I would share this as I told it to a BMW mechanic friend of mine, and he said that in thirty years he had never heard that one.
Another trick from Eric: My battery was to low to open the doors but it had just a little bit left for the alarm. The solution for me was: First the thing you need: - a second car or battery
- starting cable (booster cable)
- an extra hand
Place the minus on the engine (crawl under the car). On the driver side is the alternator, take the rubber seeling of and place the plus on it. (Same can be done with the starter)
Let the second person open the door.
Another trick from Dan S: I recently had the battery on my 1989 535i (a five-speed manual) go flat while the doors were locked. All the resident $90 per hour geniuses said the driver's door would open manually. Wrong. A locksmith friend, whom I've seen pop a " high-security" Corvette lock in 25 seconds, worked on the BMW for half an hour and couldn't get it to open with a " slim jim.&Quot; Unfortunately, I didn't see your site's contributor solution until some friends and I came up with our own, but I thought I'd pass it along. Credit goes to my gearhead buds down at Star Cycle (Ducks, old British crocks of any stripe, and enough Japanese chunks to clog up e-Bay for a year), Jimmy N. And Brian " Cliffy" A. One of those wits came up with the idea that I should jack up the car, and charge the battery using the positive cable on starter motor. It will handle a hell of a lot more current, safely, than the delicate trunk light circuit and I don't even want to think about going near a $550 BMW alternator and getting that crossed up.
How To Open A Deadbolted Door: ( Procedure courtesy of Russell Jones )
Just had a successful weekend regarding the locking on my 89 525 - where the rear door had deadlocked itself and wouldn't undo, so I was stuck with a door I couldn't open. As there were not too many ideas on this issue I thought I'd post the solution, in case anyone else has the same problem sometime.
1. Take out the base of the back seat
2. Peel off the door seal from the inside and remove plastic trim fixed to the floor (held in by large trim clips)
3. Undo the 3 screws in the trim (1 in handle, 1 behind door operating handle and 1 behind ashtray) & unscrew lock pin.
4. Pull the trim off at the top by the chrome trim, then using a long thin rod, pry out as many clips as you can down each side of the door.
5. Using a large screwdriver, push the cable end out of the door operating handle.
6. Open the window, and leaning in, grab the handle in one hand and the armrest bit in the other, and pull the trim up and out. This will be a bit stiff but it will go eventually.
6. With the trim off, disconnect the window switch and take trim out of the car (wahey!)
7. You can now take out the offending lock solenoid using a 6mm ring spanner, and unlock the door.
My lock seemed to have corroded pins on the connection, so I cleaned these up and although I thought the solenoid was knackered, thankfully it seems to be working ok now.
If you leave the solenoid disconnected (as I was going to do until I got a new one) the deadlocking and the alarm will not work. What I was going to do if it was dead, was connect the solenoid back up, but not connect it to the locking mechanism - and just mount it as far away as the drilled fixing holes will allow.

I believe I have answer to problem. I too have dead battery, doors won t unlock. In the past I ve used the manual method (turning key counterclockwise past resistance while pulling up on door handle), but this time it didn t seem to work. I hit final resistance, but door lock stem didn t move up. Not wanting to break lock, I gave up. Came searched websites. Went out, tried again. Still not wanting to break lock, I gave up again. But finally after reading about jacking up the car, positive cables to trunk lights, etc. I decided I had nothing to lose: I would go out and turn key harder than I ever thought possible. This worked.
So solution is: - Pull up on door handle while turning key counter-clockwise past resistance.
- Door handle will now pop up. But door will still be locked.
- Leave key where it is (at extreme left).
- Now release door handle and use both hands (!) To turn key counter-clockwise harder than you would ever think necessary (you think you re going to break the locking mechanism!). Door lock-stem should now pop up and door will be unlocked.
- To get key out of lock you will have to pull up on door handle while turning key back in clockwise direction.
So that problem solved. (People were doing it correctly, just not with enough enthusiasm .)
But now I have new problem. How do I open the back doors so I can get to the battery to jump it?

I have to agree with the previous post, I did also try turning the key counter clockwise and lifting door handle on both the passenger and driver door several times to no avail. After reading the above post I tried again, turning the key counter clockwise as hard as I could, only moving about 1/4.
As my thumb started to hurt from pushing I lifted the door handle slowly which allowed the key to turn a little more to the left. This in turn popped up the door lock and allowed me to open the passenger door. It was strange as I had tried this several times previously but did not notice any sign of movement. Luckily it did work in the end.
