E46 Key not locking all the time

Postby Ryan_330Ci » Wed Jun 21, 2017 6:48 pm

Hi,
Long time lurker here.
The problem I have is that my E46 coupe won't lock immediately after driving. After about 2-5 minutes it will but it won't immediately. The key itself is only around 3 months old. And when I first got it, it worked fine until about a month ago apart from the boot button which never worked since having the key.
Can anyone help?
Cheers.

Hi Ryan

Have you tried resetting it?

Hi John,

Thanks, I have tried that but now it won't unlock on the key or lock no matter how long I leave it. Any other ideas?

Thanks

It won't even unlock the old-fashioned way? Are you locked out of it?

Mine was being temperamental just with the driver's door and I ended up having to replace the motor.

The only other "trick" I can think of is to replace the battery in the key.

Sorry,it does lock when you put it in the door. It'll do that every time no worries. And the key itself is less than 3 months old.

If it wasn't working on the boot before then maybe the key is faulty?

Sorry I can't be more help mate!

Ok thanks anyway mate. I think I'll go down BMW tomorrow morning and see what they say as it's a bit ridiculous that it's been less than 3 months.

Nope, not really. All I know is the key is fine as the tested it in front of me with this little gadget thing that lights up when you press the buttons. So my hopes of it being a cheap fix I think have just gone.

According to my Haynes manual the central locking is part of the general ECU so you'll need an OBD2 scanner to find out what the issue is.

Ah, that's helpful to know. I'll get my mate with a scanner to look in to it then. Thanks again. I will keep this thread updated to hopefully help anyone else in future with the same issue.
