Central Locking problem

Hello guys, i need a bit of help regarding my central locking on my p38. When I unlock it from the remote only the doors will unlock and lock and when I open it with the key only the drivers door will unlock. I have been trying to find the answer on here but cant seem to do so.

Thanks
Luke

Do you mean they immediately relock when you unlock with the FOB?
Only the drivers door unlocking with the key can be normal if it was locked with the FOB.

Hi Datatek,
When I unlock it with the remote only the rear doors open. The drivers and passenger door do not open. If I unlock it with the key only the drivers door opens.....

But do the front doors lock when you lock it with the remote?

When you use the key in the drivers door it physically moves the lock so unless superlocked you would expect it to work.

There are 3 switches on the lock actuator in the driver's door: one is for the central locking motor (when you use the remote); one is for triggering the other central locking motors (when you manually lift/lower the lock from inside the car) and one is for when you enter the EKA code.

If no response from the remote at all and if moving the passenger door lock manually has no effect on the driver's lock then the locking motor inside the actuator has probably burnt out. There is a tiny little ring inside the motor that the brushes touch and this seems to break up very easily.

Similarly, if passenger actuator refuses to shift short of manually lifting / lowing it then that motor is probably done for too. If so, you want to start looking at the RF receiver and check it has a green dot on it and the part number matches up with the latest model. If it doesn't then replace it!

If that doesn't match your symptoms then let us know the circumstances in which the front central locking is triggered.

Hope that helps,

J

Why did I mention the switches? Because if the locks work in some scenarios then probably one of those micro-switches is acting up or the wiring loom has chafed / broken going through the door post across to the door. Or sometimes the wiring isn't put back properly in the door and the electric window snags it and chafes / breaks a wire inside.

Lock motors burnt out due to a duff RF receiver would be my bet.

thanks guys
