  • M3 drivers door lock

    Hi,
    So I leave my M3 parked up and drivers door in the deadlock position, all very good until recently I returned to unlock the door and found the key incredibly hard to turn like the key was going to snap and when I did unlock it the door popped open to the first latch at the same time.

    Some lube in the key hole and a few tests found it gritty and still stiff but not as bad.
    Over the last year I have collected up some parts for the door and window system for a refresh so good reason to get busy now.

    I ordered a new lock o/h kit, main door lock, solenoid and the plastic grommets for the lock rods some from ebay and some from Pelicans

    The door key lock overhaul kit p/n 51219061343 is basically a new lock completely disassembled with all the parts except the rubber gasket which I swapped over from the old lock.

    Oven tray and towel come in handy.

    Some where not shown in this photo there is a small roller which goes inside of the 90 deg arm.

    In the kit are two bags of lock plates they are numbered 1 to 4 in each bag.
    The inner 4 lock plates have to be the narrow “S” type this allows the lock to turn through to the dead lock position.

    The way to work all this out is install a spring and S lock plate then the key and keep working through the 1-4 numbers until the lock plate is flush with the key cylinder.
    Then it is a matter of slowly removing the key keeping the previous lock plate contained in your fingers and installing the next one.
