    Deadlocked Driver's Door- STUCK CLOSED

    I was experiencing problems with my driver's door. Typical situation of not going up all the way, so I had to open the rear door, reach in and pull the knob up manually to open the door. Irritating but not critical. Having resolved more pressing problems with this car and the wife's ride, I turned my attention to this inconvenience.

    I pulled the panel off the door and found the bracket was cracked. I fixed the bracket with a piece of sheet metal epoxied over the crack. (Same idea as Johan and Sean's rivet fix, but removal of the bracket was not necessary and I think the repair is probably stronger.) Thinking I fixed the problem, I put the door back together and left the car overnight for the epoxy to fully cure.

    When I went to check the car today, it locked fine. But now the driver's door will not unlock from the outside with the key or from the inside with the knob. All the other locks function normally, but the drivers door is now deadlocked. I cannot lift the locking knob or open the door at all. Obviously this is not workable in a daily driver. (It may have been doable when I was half my age, but climbing over the console is not going to work for me now.) So now I've moved from irritation to serious problem.

    On top of that, the door is locked closed. As a result, I see no way to remove the panel in the normal fashion. I found one post where the owner cut a hole in the door panel to access the locking mechanism. If at all possible, I'd prefer not to go that route, or cause any other damage.

    I tried the "Emergency Procedure in the Owner's Manual, but found I could not turn the key past 45 degrees. Should I "force it" to turn further, or is that process for a different problem?

    So what is our collective insight for solving this problem? Specifically, is there a way to open the door when it is in this state? Or is there a way to remove the panel or otherwise access the mechanism from the inside with the door locked shut? (Once I get the door open I'll need to know why it deadlocked, so suggestions on that front are also welcome.)

    Thanks in advance, Craig

    I have saved this vintage copy from an E34 rear door lock opening:
    E34 locked rear door procedure
    Special repair note: If the rear door lock actuator fails when the door is locked, the door cannot be opened to replace the actuator. The following procedure can be used to open the door without cutting the door trim panel.
    -remove 3 screws retaining door trim panel at upper mount of grab handle, inside door release handle, and behind ashtray. Remove plastic door knob.

    -Open the window and, using a putty knife or trim removal tool, carefully pry the uppermost part of the door trim panel away from the chrome trim by the window opening to get the upper retaining clips to release. The insertion of the tool is eased somewhat by pressing down on the trim panel.

    -Carefully pry the trim panel back, and use a small block of wood or screwdriver handle to hold it away from the door.

    -Use a long, thin screwdriver to reach between the trim panel and door, and peel the insulating sheet away from the door so that you can see the end of the lock actuator.

    -Use a bar, or a long, heavy screwdriver to reach inside the door and contact the white plastic end of the actuator that the lock linkage hooks up to. Hit the end of the tool so that the white plastic end breaks off, disconnecting the linkage from the seized actuator. The door can now be unlocked and you may proceed with the repair in the usual manner.

    Maybe that also works on the E32 front door

    Well, I guess I know how I'm spending this weekend.
    Hopefully I'll be able to report some success.
    Thanks, Gents

    There are 2 motors inside each of the four door lock actuators. One motor locks and unlocks the door, and the second motor sets and releases the deadlock.

    You want to operate the deadlock motors, to release them. Open the 3 doors (for safety!) and lift the rear seat. Remove the RM module from its sockets.

    Locate pins 1 and 14 on the BLK socket connector (X258), and insert a finishing nail into each of these 2 contacts. Pin locations in X258 are shown on pg 8500-05 of the ETM.

    Now use a 12V booster pack and briefly (1 second) connect NEG to pin 14 and POS to pin 1. You will hear the deadlock motor operate in the drivers door, releasing the deadlock. Now you can open the drivers door as normal.

    Wiring shown on pg 5126-02 and 03. Again, leave the 3 doors open while you are doing this, for safety!

    To prevent any future deadlocking, cut off pin 14 of the RM.

    Just to clarify the lingo. By "deadlock" do you mean "deadbolt" or am I not correct?

    If the actuator is unlocked and you pulse the deadlock/deadbolt motor, then when you next lock the actuator, it will STAY LOCKED.

    It is not possible to unlock the actuator either electrically or manually, until the deadlock/deadbolt is released.

    I never want my actuators to deadlock/deadbolt, so I always cut off pin 14 of X258.

    So it is the same thing. Just checking as I thought a lock has tumblers while a bolt does not

    Yes, the actuator is just an electric actuator device that pushes or pulls a linkage rod, quite separate from the keyed door lock cylinders.

    The key turning in the lock cylinders is opposed by the actuator rod, which refuses to move at all, when deadlocked.

    As shogun notes, there are 12 wafers in the lock barrel. BUT. we don't truly need to maintain all 12 of these. We could use just 5 or 4 or 3 or even 2 wafers and our key would always unlock our door.

    Car thieves will not expect that we have dropped our guard from 12 wafers to 2, say.

    I have not spied any car thieves lusting to steal my 26-year old BMW 735iL sedan. (I wish they cared for her!)

    Just to update those with interest, I followed E32FAN's instructions as far as I could and had success. All I needed to do was remove the General Module from its socket and the actuators pulsed. After that, I had no trouble locking and unlocking the door. (I also took advantage of the rear seat removal and did a "magic reset.")

    However, the disabling instructions were over my head. I'd like to disable the deadlocking feature as E32FAN suggested, but feared pulling the wrong pin. What does "Pin locations in X258 are shown on pg 8500-05 of the ETM" refer to? I couldn't find a black socket in the GM and couldn't tell which one of the four sockets was number X258. Are there more detailed instructions or guidance available on this topic?

    Thanks, Craig

    The colours are there to identify the sockets

    in the GM
    x253 26 pins GREEN
    x254 26 pins WHITE
    x255 26 pins YELLOW
    x332 5 pins BLACK

    in the RM
    x258 20 pins BLACK
    x259 20 pins WHITE

    The pinout is shown on page 8500-05 http://shark.armchair.mb.ca/~dave/BMW/e32/e32_93.pdf that is close to the end of the ETM, there you see diagrams/drawings of all the plugs under connector views with all pins shown and where they are.

    I didn't know what the "ETM" was. Now I do, and where to find it. Once again, thank you Shogun and E32FAN.

    Erich,
    I looked on realoem for the microswitch but all I found was the door lock assembly. If I replace e the whole thing I guess I should order your door latch gaskets?

    Depends on your door handle (cover) gasket condition, anyway, I have the gaskets on stock, whenever you need.

    Many thanks. I had been looking under the door lock page and never figured there was a separate list for switches. I feel stupid not looking deeply enough.
    Regards,

    I had no idea there was a separate section for "various switches"... I too was looking under the door lock section. My driver's door has stopped locking in the past few months. It would lock fine via the trunk or passenger lock, but after a battery disconnect, the door locks had to be resynchronized. Impossible to do when the drivers door will not register the key's position. Have not had locks due to this. I also have lately had the door locks unlock when locking from the inside. They just pop back up as soon as I push it down on the drivers door. This is typical when it needs to be re-synched. Hopefully it is not a bad servo.

    Have to pick one of these up.

    There is wrong feedback to the GM, because one lock does not work, then it unlocks again to tell you. Here described :
    This Service Information Bulletin supersedes S.I. 61 01 92 (3460) dated January 1992. It incorporates additional information on the new General Module software for E32/E34 vehicles.
    Please remove and discard S.I. 61 01 92 (3460) dated January 1992 from your S.I. Binder.

    SUBJECT: New General Modules (GM) MODELS: 7 Series (E32), 5 Series (E34)- Vehicles produced 9/91 and later
    Situation: New general modules have been used in production since September 1991 in all E32 and E34 models. The software has been completely revised (details of these revisions are found in the attachment to this Service Information Bulletin). Part numbers have been changed to reflect these revisions, as listed below, as of September 1991. Model Part Number
    E32 61 35 8 356 095,
    E34-up to 61 35 8 356 095 9/91 production
    E34-9/91 and later production 61 35 8 355 812
    Note:
    E34 vehicles produced 9/91 and later have different central locking system components from earlier E34 vehicles; therefore, P/N 61 35 8 355 812 is used only in E34 vehicles produced 9/91 and later, P/N 61 35 8 356 095 can be used in E34 vehicles produced prior to 9/91, and in all E32 vehicles. When the general module is connected to the vehicles electrical system, it will recognize (and store in memory) the vehicle configuration, such as:
    - with/without power windows
    - With/without power sunroof
    - with/without wiper contact pressure control
    - with/without headlight washers
    Important Information
    All general modules must be plugged in only after disconnecting the vehicle's battery. If the vehicle's battery is connected when the GM is installed, undefined signal contacts can cause an incorrect vehicle configuration to be stored, resulting in the impairment of
    one or more of the above-mentioned systems. If one or more of the GM functions are impaired in this matter, the GM can be "cleared" by disconnecting the vehicle's battery for at least ten seconds.

    GM Function Changes E32/E34 (Beginning with 9/91 Production)
    - Repeat and Time interlock for headlight washers:
    · Time interlock: 3 minutes
    · Headlight washing at fifth windshield washing after time interlock.
    - Intensive washing pump operating time reduced from 3 to 2 seconds
    - Minimum interval for intermittent wiping is programmable down to 2 seconds (previously 3 seconds)
    - Increased wiper contact pressure during windshield washing cycle is now also provided during dry wiping portion of the cycle (previously only during washer pump operation).
    - Previously, the GM would react to opposing signals (eg., an unlock signal while trying to lock, as with a defective microswitch) by carrying out the first command, then the opposing command (e.g., locking, followed immediately by unlocking).
    Repeating the first command then results in carrying out that command (e.g., try to lock again, and locking is now carried out).
    This function ("Asynchronous Position") is omitted in the new GM for all E32 models and E34 models prior to 9/91 (P/N 61 35 8 356 095), and remains in the new GM for E34 models after 9/91 (P/N 61 35 8 355 812) only for central locking commands "lock" and "double-lock".
    - After unlocking is performed due to crash sensor activation, the locking command is now reactivated by double-locking with the key from either the driver's or passenger's door.
    - The "one-touch" operation of windows has been expanded to include all four windows in the opening direction. The driver's window still has "one-touch" operation in both opening and closing directions. Interruption of the "one-touch" feature of the driver's window in the closing direction is still accomplished by depressing any window switch (in any direction), or by depressing the sunroof switch in the "tilt" direction (provided the sunroof is not already in the "tilt" position). Interruption of the "one-touch" feature of the sunroof in the closing direction is still accomplished by depressing the sunroof switch (in any direction).
    - The switch-off delay of the interior lights which occurs after entering the vehicle and closing the driver's door has been reduced from 20 seconds to 15 seconds.

    I know i'm late to this but mine had the same problem and it was simply because the locks were out of sync. I simply went to the pass door and locked and unlocked the car and kapow, the drivers door unlocked.

    So after a 2 year hiatus with the car in storage, I am planning my spring repair program. Before I take apart the door lock to replace the microswitch, I wanted to be sure of my diagnosis. The passenger front door will lock and unlock all the doors. The driver's door will lock all doors but not unlock all doors. What is the best approach to test the system to identify the problem?
