Central locking system

I have 2003 BMW X5. The remote will not unlock the car but it will "pop" the trunk lid. I believe there is general module and central locking module that could be the problem. A mechanic dianosed it as the general module but i purchased the module but the pin connectors dont match. What the problem?

    '03 X5 central locking failure. locks will only operate by manually inserting key in driver's door. no lock in passenger side door. Interior lights do not come on when doors are open, neither does the security warning light.

    Interior switch is not the problem. Replaced it with one from 01 X5, same problem.

    '01 fan blower was defective, had it fixed. Now same trouble with 03 fan blower.

    I have a 2003 BMW 530i and the doors will not lock/unlock using the button on the keyless entry remote or using the central locking button inside the car. The keyless remote will open the trunk. Interior lights do not come on when doors are open, neither does the security warning light. I've check the fuses and they all appear to be good. Interior map and courtesy mirror lights all work as well. I would love any help possible with this one.

    Have the same remote locking problem, X5 2003. SOS PLEASE

  • bnabours Feb 26, 2009

    I am experiencing the exact same issue in my 2002 530i, the remote does not unlock the doors, but does unlock the trunk lock.

    I have been looking into this issue and have seen some interesting posts on bimmerfest stating that someone with this same issue had found a dealer tech who ran a diagnosis on the BCM (Body Control Module) and it had somehow been changed to 'Shipping mode' the dealership had to reprogram the BCM and it subsequently fixed all the locking issues.

    Not sure how much the stealership will charge to reprogram the BCM for you, the tech rate is usually around 150.00/hour (US) saw the BCM's used on eBay for about 100.00.

    I have the same problem with my 2003 BMW X5, battery died and after the car was jumped the central locking system, interior light, remote key entry, and alarm stop working, The key does open the back door but nothing else. I tried to reset the key fob, but that did not work.



    Is the a BMW problem or does anyone have a fix for it.

Bmw 2004 doors wont unlock


Could be a few things. Do they unlock from the central locking switch in the car? Close all the doors first then push the button. Do they unlock with the key remote? Does the drivers door unlock when the key is inserted? If they don't work at all check the fuse in the trunk area on the right side. There is a panel that pulls down and reveals 5-10 fuses.

My fuel cover does not lock with central locking


According to WIS, the remote boot release is directly connected to the PSE via CAN
The pneumatic system equipment makes vacuum or pressure available for the following systems:Central locking (CL), (pressure, vacuum)Remote trunk release (RTR), (pressure)- actuation via remote trunk release switch or via radio
AD80.20-P-2002-02B Remote trunk release, general notes on Models 202.01/02/12/12 as of 1.6.97,diagnosis, advanced information, RTR 208, 210 as of 1.3.97, 210.081Actuation of PSE control module:The remote trunk release switch (N72s15) is connected to the PSE control module (combined) (A37) via CAN data buses. The remote trunk release radio signal from the key is conveyed to the overhead control panel control module (N70) via theantenna. This transmits the signal to the electronic ignition switch control module (N73) via CAN data buses. If a valid signal is recognized there the PSE control module (combined) (A37) is actuated via CAN data buses. The remote trunk release IR signal from the key is conveyed to the respective door control module (N69/1, N69/2) via the IR receivers (A26/1, A26/2). This transmits the signal to the electronic ignition switch control module (N73) via CAN data buses. If a valid signal is recognized there the PSE control module (combined) (A37) is actuated via CAN data buses.
If the trunk lid is unlocked the LED in the remote trunk releaseswitch (N72s15) is actuated by the PSE control module (combined)(A37) via CAN data buses.
Special features on model 208.4 (Cabriolet)The trunk lid cannot be released remotely with the transmitter key.The rollover bar (RB)/soft top operation control module (N52)signals via the CAN interior data bus whether the soft top is lockedor unlocked or the power soft top switch (S84) is operated. As long as the CAN message reads:"Power soft top switch (S84) operated" or"soft top unlocked"the trunk lid cannot be released remotely.

2002 bmw 530i key does not (remotely) unlock doors or trunk but they work fine manually.


Unlock vehicle. Enter vehicle. Close driver's door. Switch ignition ON and OFF. Remove ignition key. Press and hold unlock button. Press lock button briefly 3 times within 10 seconds keeping unlock button depressed. Release unlock button. Some models: LED flashes slowly for 10 seconds. Some models: Central locking system locks and unlocks rapidly to indicate correct programming. Repeat above procedure if central locking system does not work and LED does not flash or LED flashes continuously.

I have a 2001 BMW 325i. It started with the rear light display on the dash came on but nothing was wrong with the rear lights. I checked the fuses and nothing was wrong. Now the locks don't work. Only...


The connector on the rear lights gets burnt and you have to replace the connector, the burnt wire, and the taillight assembly. For the locks it could be a few things. Does the central lock button work all the doors? Does the remote function work with any doors, or trunk? Could be anything from the driver's door lock actuator to the general module for the car. If you have a scanner to check the ZKE module and code "general locking, unlocking relay" is there then a new general module is needed. The relays are built into it.
