Part 2 : Anyway, I took out the part ( Central door lock ,and hazard button,are together) again. AND it is not working properly because it is made of plastic (sticker says Made in Mexico" !) and the plastic frame holds it altogether. I have had to tape it together a couple of times , finally keeping it tight. When you push down on the button ,there is a spring , and if the frame gives it won't work. so that makes it stop the doors from unlocking ,and if itis stuck at lock, then the door fob won't work either . I got it back together firmly, and ALL it Well! . I shall have to get a new one eventually. But I was looking it up ,on the forum ,and was finding people are going to great lenghts to repair the Door lock "Actuators" , and still have the same prob. So my suggestion there , is to replace the central locking button, Or take it apart to clean it if you are able. It is very simple. Fix, or replace and plug it in.
Part 1 : So I have had trouble with the central lock as it had some ,coffee probably ,spilled in it. (Starbucks, or Tim Hortons with lots of cream and sugar to make it sticky, when it dried!). To start off, it is sitting right under ,and in front of, the cup holders. So that is inevitable.. Well it didn't work when I got the car , so I took it out, took it apart and cleaned it , put it back in and it worked fine for months.
One day it started working intermittently. when I was taking a passenger ,one time, the locks wouldn't work. There is only one other way to open the door- the key - BUT it only opens the Driver's door , not the others! This is a 2000 328i , with 4 doors, and only one door would unlock. My friend had to CLIMB over the driver's seat to get in! . That I find is an issue in itself- any thoughts on that? maybe there is another way to get the other doors open?
