my keys (i got 2) can't even open the passenger door lock! i think i
can locate the plate light but what do u mean by 'use that wire to
power up the system'? do u mean making a short circuit?
You need to remove the *trunk* light and hook up a slave battery to
chassis and the live wire. This should send power to all the permanently
powered things like the central locking. The license plate light is only
powered if the lights are switched on.
However, there's a caution about this. If your battery is heavily
discharged this might make more current flow from the slave battery to
yours while it charges it than the wiring can handle - after all the boot
light is only a few watts. So to be safe, I'd wire a 21 watt bulb in
series with the connection. Leave it for a few minutes to charge the car
battery slightly. Then with a bit of luck the central locking will operate.

Depending on model there you can mechanically unlock the driver (or LHS)
door. Once you get into the car you can read how to do it in the manual ;-)
A Google in the news groups should turn it up though.
Otherwise you can charge up the battery enough through the boot light, but
do not over current or you will blow the battery supply fuse and then you
will have to break a window.

thanks for all the input. i can now unlock the door using the
emergency unlock method. the only thing left is to check if any
electrical or electronic problem remains after a new battery is
installed. once again, thank you.
I am currently -- as we speak -- playing with the door locks on my '94 E36,
and I played with the trunk lock a few weeks ago.
I can say without reservation that the door locks are mechanical, and they
work by the key on the door you are trying to lock or unlock. The other
doors operate by electric motors, but the lock set with the key in it
operates mechanically. When you use the key on ANY of the locks, that lock
operates the latch directly -- unless it has other problems -- and this lock
will work a switch that operats the rest of the locks on the car. Obviously,
with a dead battery, the other locks will not operate in this way, but the
door that you insert the key into will lock and unlock properly.
