I have an '87 635CSi with key-operated door locks (no remote locking). When I last locked the doors from the driver-side, the locking action "felt" different...felt like something went "over-center". When I tried to unlock, the key in the same driver side door would only rotate slightly, and caused no motion of the locking button (plunger). I tried to unlock at the passenger door, and the key turns about 30 degrees, moving the locking button up about 1/2 normal travel, but cannot move the locking button any further. The trunk lock works just fine with the key(s). I have been told by a couple of BMW people that this is an acknowledged problem called either "dead-bolt" or "inhibit" mode. But no one (including the local dealer) has a clue how to gain entry into the car, other than breaking out some glass, then "removing a module from under the dash, and shorting out a couple of terminals". I really hope that there's some non-destructive way to restore normal operation to the door locking system. I've acquired a complete slim-jim kit, and I'm a former Porsche mechanic, so fairly capable mechanically speaking. Can anyone tell me what it is that has failed to cause this condition, and what I need to do to un-fail the system? At this point I can't even tow the car or winch it up onto a bed, since it's in gear, and safety brake is "on". HELP!
I could also use a REAL 635 service manual. I have two 635's. One is an '84 EURO with a different (and remote) door locking mechanism that has never failed. If anyone has a lead on a decent/accurate 635 service manual, please let me know.
Thanks...
