Help! Locked out of E34 M5

[Jim Walsh <jimw@xxxxxxxxxxxxx>]

My E34 M5 was hit in the parking lot the other day.  The trunk won't stay
closed, so I removed the bulbs from the lights in the trunk to keep the
battery from dying so quickly (carry a portable booster battery in the car
so it isn't so bad).

Today I had a bunch of race tires and such in the car, so I locked the door,
being careful not to set the alarm system.  I figured I could just manually
open the door with the key if the battery died.

Looks like not!  The key must be totally electrical.  There's a detent
further past the regular unlock position, but I can't get the doors to
unlock no matter what I try.  And of course I can't get the hood open to
jump the battery (or of course the rear doors to get at the battery itself).

I thought I recalled some emergency procedure, thought I saved it, but
apparently not.  If anyone has any better ideas than calling AAA or a
locksmith (and of course charging to the idiot that hit me), please let me
know!

Thanks,

Jim Walsh
