BMW E46 318ci 2001 Central Locking Issue!

Hi all, first time user so please be patient. Recently my key fob has decided to only open the passenger door and boot and not the drivers side. I have checked all fuses and they are fine. Any ideas before I start removing the door card and playing around? All help is appreciated.

It is probably one of two things. Either the actuator in the door is faulty or it could be the GM5 module that controls the door actuators. There are small relays inside the GM5 module which eventually fail and cause door lock/unlock issues. Check out GM5 module on this forum, it will describe the symptoms and how you can get it fixed assuming that is the problem. Can you open the drivers door with the key OK? Also, does the drivers door open/lock if you use the lock/unlock button inside the car? If the drivers door is unlocked, can you lock it with the key fob? That will all help to diagnose the problem. Good luck!
