    Hello!

    On mine BMW 116i, E87, 2005. I am having a central lock-up / unlock system failure (using either a key or a remote control) so here are some facts:

    -The key locks-up and unlocks only the driver's door.

    -Central lock-up switch in the booth locks-up and unlocks all the doors and the trunk but does not lock petrol plug cover.

    -If I mechanically pull the shutter for locking-up petrol plug cover, then unlock with the central lock-up switch in the booth, shutter retracts (unlocks petrol plug cover).

    -Neither of the remote controls (telecontrols) work.

    -Computer check of the vehicle does not recognize any defect.

    -Tester in the authorized service does not recognize any defect.

    -Authorized service have tried to alter the remote control receiving circuit no positive result.

    -Authorized service have reprogrammed CPU no positive result.

    -Fuses O.K.

    What shall I do??

    There is a coding feature for "selective locking"

    This is with the remote though - one press will open just the driver's door, the next press will open all doors.
    The centre button can be programmed to either lock or double lock.

    try open driver's door, then turn the key again to open twice, as see if more doors open the second time.

    Did the dealers read the fault codes from the body control module?

    First thing to do would be be to get remote controls working.
    There is usually a way to get them synchronised with the car.
    Have this been tried? There might be a guide in the car's handbook.

    Hi Ronnie, thank you for answering..
    the exact answer to your question I do not know; the dealer sad that their tester does not recognize any defect, they have tried to alter the remote control receiving circuit but with no result and they have reprogrammed CPU also with no result.. could the fault codes be read from the tester?

    the simmilar answer I must give to you TheEnd; I do not know did the dealer trye to synchronise remote control with the car but mine cars handbook says nothing about it..

    I'm looking into it, incase there is some syncing process, but the key batteries may be dead.

    They are supposed to charge up when plugged into the dash, but if left for a while, the battery can run out of power. What i'm checking is if they should work straight away after charging, or need to be set up before hand.

    I think the key batteries are fine because car handbook says that board computer will recognise death battery and will signal it, and when this failure began first i tried spare key/remote and nothing happens...

    do you think it is ok that the key locks-up and unlocks only the driver's door?
    it just does not seem logical....?
    is it possible that some of the main locking actuators are in the drivers door and some of them is not working?

    thanks to the guys on this forum i found out that the key locks/unlocks only the drivers door so the petrol plug cover stays unlock all the time because it couldnt be locked with central lock-up switch in the booth...

    i have recently visited dealer again and their new tester hasnt found any failure (again!);

    is there anythig else i can do?

    please help!!
