RE: Help! Locked out of E34 M5

[Jim Walsh <jimw@xxxxxxxxxxxxx>]

Thanks, that did it (found out a little earlier tonight), bent the key in
the driver's door trying it, but it did work in the passenger side, nothing
I'd read mentioned that.

To resynchronize the locks, lock the other 3 doors electrically, then turn
passenger lock back the other way with the key.

Thanks everyone for all the advice!

Jim

It's actually pretty easy, but not having done it in years and not having
an E34 or a manual here, I'm doing it from memory.

The trick is to use the key in the PASSENGER side door.  Turn the key in
the direction of unlocking (should be toward the front of the car, or
clockwise) until it won't go any further.  While still applying light
turning pressure, lift up on the outside door handle and turn the key to
boldly go where it has never gone before and manually override the lock.
Hope it works for you.

In normal operation, the unlock action of the key operates the power locks
through a micro-switch (Lucas part).  When the battery is dead, the manual
override has to do the trick.  This is the same on E32 with the exception
that the early cars (probably '88 only) operate from the driver's door.  I
think all E34s do it from the passenger side, and I'm sure that's the case
in your vintage.  Once your battery power is restored, you may need to
reset the lock by pushing down on the door lock knob on the passenger door,
and possibly fiddling with the door handle some more to resynchronize it.

Now, how many people know how to do the same procedure in the Z8 which has
no visible key openings and relies on the key-head remote?  If you know the
answer, I'll bet you were at Gateway Tech last weekend.
