OK, I bet there is a simple way to open the doors when the battery is dead..
anyone know how?

I have the window down about 2", tried a coat hanger pulling up on the
lock.. no-go.. seems like it's being held down.

Thanks for any comments.

IIRC:  Put the key in the driver's side lock.  Pull up on the handle, then
turn the key.

The driver's door lock is mechanically actuated, you should be able to open it
with the key.

If that fails, the hood latch can be opened from the front grill and then you
can connect a charged battery to operate the electricals and start the car.
There's a suitable connector in the left side of the firewall.

Neither worked.. on the drivers door. The hood opens from the windshield
side, how does it open from the front?

The key, in any front door, or the trunk, does not work any lock.

Other ideas?

Thanks

Seems that in older models of E34 you must pull the door latch to allow the key
to actuate, try both front doors. For sure in my '94 E34 you can open any lock
with a flat battery.

Regarding the hood latch I have seen it beig opened with a bent caot hanger from
the front grill, the latch is there, actuated by a cable.

Other option is to jack up the car and connect a battery to starter motor's
positive terminal and chassis for the negative pole.

By the way, never apply electricity while lying below the car because if
connected incorrectly the starter motor can rotate and the car drop from the
supports.

Connect the cables without power and only when safely away from the car connect
a battery to them.

1. Try the master key in the driver's door.  On older models this is where
German drivers would sit i.e. on the left or

2. You should be able to open the boot mechanically, insert key and rotate
anti-clockwise.  There may be some resistance to go past "un deadlocked" as
I doubt the lock has ever been used.

3. Once you get the boot open charge the battery either directly (if it is
in the boot) or via the boot light - set the charger to low current
otherwise you might blow the fuse.

Have you tried turning the key that lets you unlock the trunk? The battery
is in the trunk.

The battery is under the back seat.. not in the trunk. I will try both front
doors, lifting the handle, to see if this works. Since the hood opens from
the windshield side, the hood latch must be near the windshield, not in the
front of the car. I will see if I can see it, but I don't think so.

On my 3 different 3 Series cars, the doors can be opened by the key even
then the battery is dead. The door lock mechanism is operated manualy by the
key, which then operates the remaining doors electrically -- assuming the
battery works.

Apparently (according to several others), you turn the key, hold it, and
lift the handle all at the same time. This allows you to open the doors
manually when the battery dies.

The first thing you have to understand is, the car MUST be able to be
opened, even if the battery is dead, since the battery lives inside the car
behind the locks that are inoperative when the battery dies.

Give it a f.cking break, fer chrissakes.  Your beef with Jeff is
pretty damned old and tired now.  Take it to e-mail with him, or hunt
him down and kill him or whatever it is that will satisfy you.  Spare
the rest of us from it, please...

I wasn't blubbering at all. I said the doors open with the key, and I was
right -- as several others said the same thing.

OK, here's what worked.. I took a coat hanger, made a loop around the end so
it would fit over the 'push-down' lock, and with the key turned to the open
position, I pulled up on the lock.. this worked. W/O the key over to the
'open' position, I could not lift up the door lock...

Charging the battery now..

Thanks! When the battery in my 90 535i, 5spd, 118K miles, died, I too
was stranded. However, I followed the direction above, "Put the key in
the driver's side lock.  Pull up on the handle, then
turn the key" and that worked for me. Nevertheless, its good to have a
second option!
Scott C - 22 Aug 2008 00:40 GMT
Wow, then this should have worked for me.. not sure why it did not..
