has anyone ever fixed their central locking on an e30?

[gearheadE30]

I don't have central locking ;). No electrical crap to go wrong there.

How about this one, All 4 of mine work when I lock them from either trunk or two front doors. But the passenger front door will not unlock with the rest of them. My hypothesis is that the mechanism needs regreased or something It is very hard to turn, and it use to work.

Is that a possibility?

My central locking didn't work on my first E30. Took the whole thing apart, Cleaned the pins and replaced the module and it worked great.

I have fixed plenty of them. What would you like to know?

I'll go to lock the car at the driver's door, and here's what happens...

- I turn the key right to lock it
- The doors lock
- I turn the key to the left to remove it
- The doors unlock
- I turn the key to the right again to lock it
- The doors lock and I remove the key.

The question, why does it take two times to lock the car?

Another question, sometimes I will try to lock the car from the passenger's door and the key won't turn to the left (to lock the car.) It feels like something was stopping the key from turning. Any ideas?

I would imagine the problem is the central locking motor piece( the red thing in the door that pulls it closed)- in the drivers door

I looked in the door and didn't see anything red. I saw a black box on top of a white box that looks like it did the pulling and pushing for the lock. Is that it?

So let me ask you a question: Do you want to learn HOW the thing works so you can fix it, or do you just want it to work?

From what you have said it sounds like you need to rebuild the drivers door lock cylinder, then replace the central lock control module, and possibly the actuator.

If you wanna learn HOW it works, go read your owners manual first, then go to www.wedophones.com and download your electrical troubleshooting manual.

Keep us posted!

when i turn the driver's door lock (outside) to "dead bolt" all the way to the right. it gets stuck there and i need to take my spare key and use the trunk to actuate it while i jimmy the door lock back on the drivers door.

everything else works flawlessly. i think it is something physical not electronic. it is just like it gets stuck when i turn the drivers door all the way to the right. any ideas?


BTW i replaced the tumbler assembly when i first got the car 4 years ago because the PO (my mechanic said they tend to get warn out and my was loose)

have you tried to adjust the mechanism itself, sounds like its getting bound up.

I can lock/unlock my passenger door with the key but not the drivers door. I can unlock the drivers door with the key but when i turn it 45º clockwise I can hear a relay click in the door and then another click but nothing happens.

I'm not too sure, you might want to check the control module as posted earlier. I tried swapping mine out to no avail, so I think he may have cut wires or something.

My car locks and unlocks just like a car without power locks. I have no problem locking/unlocking and hear no relays click.

The PO of my car disabled central locking because, "it's prone to going bad." Great, thanks. I still haven't figured out what he did to get mine working again.

I'm wondering if thats what the PO of mine did as well. He certainly wasn't the smartest about cars and didn't seem to care much about doing a job right when it needed to be done. My problem is obviously that my central locking does not work:

Mine turned out to be corroded pins in the doorjam connector and 1 bad passenger side actuator. Then went to keyless entry soon after.

thats a broad question. Narrow the source of your problem. Mine was with the circuit board



You could also have problems with the connection at the door

Or the locking mechanism at the key hole.
