SOURCE: mini central locking not working

There are two settings for the fob to unlock doors. One is both doors unlock, and the other is the drivers door on the first click, and then after waiting about two sec. pushing again unlocks the passenger door. The dealer has to set this function. I find that if I don't wait long enough, the passenger door does not unlock.

SOURCE: 2004 Honda Accord Euro. Central

I am a mechanic and had the same problem with a 2005 Acord that I purchased couple of months ago. Contact through the trade provided little help. The problem arose during a week that we in Adelaide, South Australia had a record o 40+ degrees centigrade heat. I noticed the drop knob slightly moving when the immobiliser was activated, but the drivers door failed to lock. Key locking would lock all doors however.
The cost of a door actuator from a Honda dealer was $185.00 (Aus), about $250 (US). The spare parts guy told me they had them in stock and sold a number of them. As a result I decided to find out whether the actuator was in fact faulty. I susequently removed the door lock and actuator assembly from the door. (A fiddly type job). The actuator assembly is in a plastic sealed assembly. By using a lot of patience and a box cutter I was able to cut around the assembly and then carefully lever the plastic housing apart. This revealled the small electric motor (similar to a slot car motor) that drove a worm and wheel assembly and a system of cams that actuated the door lock system. I found on dismantling the electric motor that the armature was coated with grease from the wormwheel /cam assembly that is mounted above the motor when installed in the vehicle. I cleaned the armature and brushes using superfine wet and dry carborundum paper, undercut and cleaned out the two armature segments of all remaining grease with a solvent. The motor was then tested with 12 volts and found to be ok. I then reinstalled the motor and glued the housing back together. It now works fine. I believe the housing was either initially overfilled with lubricant or that the high ambient temperature caused the grease to melt and flow into the elecric motor contaminating the motor. (There is no seal between the gearbox and the electric motor). The job took a few hours from start to finish but I saved the cost of purchasing the part and didn't let it beat me.
Cheers and beers

SOURCE: 1999 Audi A3 1.8T Electric Windows and Central Locking Won't work

will your passenger door open with the key and is it just one side that your windows are not working or both. if its just one side it might be your regulator motor in the door thats not working if its both it might be your central locking pump usually in the boot. however if both of them are working fine it could be that your key needs reprogrammed however i think the 1st 2 are more likely to be the problem.

You will need to replace the driver door switch. You can try to pick a switch up from the dealer or a local car wrecker (i.e. Pick-n-Pull). It will involve learning to take apart the door trim panel.

shorted wiring in doors or shorted door lock actuator in door. A grounding of a wire makes them lock normally. SO, any bare wire touching metal will ground it and lock the doors.

Principles of Operations
The Door Switch Lock Function When a door lock switch is moved into the lock position or a door lock cylinder is rotated to the lock position, the door lock switch grounds the lock circuit input to the central security module (CSM). The CSM then provides 12 volts to one side of the door lock actuators contained in the door latch unit and simultaneously grounds the other side of the door lock actuators. This completes the door lock actuator circuit, causing the door lock actuators to rotate a cam assembly, which then locks the doors. The 12 volts that the CSM provides to the door lock actuators are provided to both door lock actuators from a single pin on the CSM electrical connector.
The Door Switch Unlock Function When a door lock switch is moved into the unlock position, the door lock switch grounds the unlock circuit input to the CSM. The CSM then provides 12 volts to the opposite side (relative to locking the door) of the door lock actuator(s) contained in the door latch unit and simultaneously grounds the other side of the door lock actuator(s). This completes the door lock actuator circuit, causing the door lock actuator(s) to rotate a cam assembly in the opposite direction, which the unlocks the door(s). The 12 volts which the CSM provides to the door lock actuator(s) are provided to each door lock actuator from the individual pins on the CSM electrical connector.
--------------------------------------------------------
CSM Self-Test The CSM has a self-test which can be entered into by using a diagnostic tool. This self-test will monitor the following CSM door lock inputs:
  • Unlock switch (DTC B1311)
  • Lock switch (DTC B1300)
  • Exterior lock switch (DTC B1309)
  • Exterior unlock switch (DTC B1341)
Before running the self-test, the following conditions must be met:
  • The ignition switch must be in position II
  • The driver and passenger doors must be unlocked
  • The driver and passenger doors must be opened
  • The hood and liftgate must be closed
  • The set/reset switch, and liftgate release switch are not actuated
It is important to note that all of the diagnostic trouble codes (DTCs), with the exception of B1551 and B1553 can be retrieved with the self-test. DTCs B1551, and B1553 are continuous and will only be retrieved if the liftgate release is operated prior to retrieving the continuous DTCs.
Inspection and Verification
  1. NOTE: Make sure that the battery is fully charged before starting electrical diagnosis.
    NOTE: Prior to carrying out the CSM Self-Test, make sure that both the driver and passenger doors are open.
    Verify the customer concern.
  1. Visually inspect for obvious signs of mechanical and electrical damage.


Visual Inspection Chart Mechanical Electrical
  • Binding latch mechanisms
  • Binding linkage
  • Misaligned door
  • Central junction box (CJB) fuse(s)
  • Wiring harness
  • Electrical connector(s)
  • Door lock switch(es)
  • Door lock actuator(s)


Module Controlled Functions
The central security module (CSM) covers the following functions:
  • Central door locking
  • Double door locking
  • Anti - theft alarm incorporating
    • forced entry
    • radio theft
  • Radio frequency remote control of
    • central door locking
    • panic alarm

For additional information, refer to Section 419-01A Anti - Theft - Active, Section 501-14A Handles, Locks, Latches and Mechanisms, and Section 501-14B Keyless Entry/Computer Operated Locks.

The CSM is in the passenger side kick panel I think.

Good luck

If the key turns in the lock, but does nothing, then the linkage has become disconnected or broken. The key is mechanical to the lock and the lock has a electrical switch to operate the central locking unit. Could be a simple broken clip from the lock barrel. Hope this helps

When you use your remote or insert your key in the Drivers Front door all the door locks should work at the same time by the door lock motors electrically. If you have to manually unlock the door because it will not lock or unlock by the lock motor, you need a door lock motor. The drivers and passengers front doors can unlocked with the key manually only. The rear doors you have to pull up the latch. 
If NONE of doors unlock electrically with the remote or drivers door lock, intermittently or all the time, you will need a Central Locking Electronic Control Module. Pressing the remote button you will hear the "beep", but no door locks will fire at all. 
If you have a few odd door locks not working intermittently or not at all, you will need a new door lock motor for each door lock that malfunctions. You can hear if the door locks are working electrically. Yes, they are common problem. 
If you can hear the door lock motor working but the door still doesn't unlock you need to take the door panel off and lubricate the door latch assembly and work the lock, loosening it up. This is common as well.
Sometimes a bad door lock motor can blow the central locking fuse. You will notice it because it will take a second or two longer to lock and unlock compared to the others. If the door lock motors seem fine, install a the next step up in amperage fuse. (From 15 AMP to a 20 AMP)
