Remote won't unlock passenger door

When i press unlock on the remote the driver door unlocks but the second press does not unlock the passenger door. At first it was intermittent but now it almost never works. The button in the center console always works.

Anyone know what might be wrong?

its a 2002 330CI

I've had the same problem with my 325 for about 2 years now. It only happens once every 10 times or so but the center console wont unlock the passenger door either unless the car is completely locked and then unlocked again. The BMW dealership told me it might be due to "solar flares that add radiation to the atmosphere interfering with radio transmissions..." Bullshit. Never been able to reproduce the problem for them so they won't even check it out.

mine just started doing the same crap. it wasnt opening anything at all, doors or trunk. i had to manualy put it in the key lock to do all that, then I took it to the dealer and they couldnt find a problem. Tried telling me it might bet the tint cause they couldnt get it to do what I said it was doing. It worked for a couple days after that and now the thing is acting stupid again!!!

Happened a few timed before to me. Happening again on my 2001. Key fob unlocks driver door and trunk but no passenger doors on second tap. BCenter console button wont unlock doors until car is started. I thought it was due to low battery last time, but I have new battery now and recently put like 200 miles on my car.

Door lock problems that mysteriously come and go are usually due to a bad general module.

Anyone has a fix for the doors not locking or unlocking with the remote key? My car locked me out and I had to go into the truck to unlock the door and someone called the cops on me because it looked as if I was trying to steal my own car. Now my key will not work to manually lock or unlock my door it just turns. Can anyone help?

Remote won't unlock passenger door

The lock cylinder in the driver's door is broken. That's why it just turns. You need to get that fixed or replaced. Here are instructions on how to get it out www.bmwgm5.com/lock_cylinder.htm

It sounds like your remote is not working either. Get the key tested and if it's bad buy a new one or get it fixed.

There are two ways to unlock the doors from the outside. You should never rely on just one. If one way breaks FIX IT. If both break then you are just screwed.

Reviving an old thread, since this is the one google found.

I just started having this happen on my 2002 cic.
Twice now the passenger door has not unlocked when I push the unlock button on my key. When that happens the center lock button does not work (on the passenger door, it still works the drive door), I have to lean over and unlock the passenger door by pulling the handle.

My key is programmed to unlock all doors on one push. I usually drive alone so this may have been happening before and I did not notice.

It is frustrating. I just went out and locked and unlocked many times and it worked fine.

Any ideas? I'm guessing a lazy, or corroded contact, on a relay somewhere. Perhaps in the "general module"?

edit: maybe it is because I don't have a passenger opening that door enough?

Mine started doing this a few months ago. I replaced the Door Lock Actuator with a a used part from a 41k mile car and it's been fine ever since.

Lack of use has been cited as a reason many times. DLA's on the E46 Coupes are notorious for going out.

Which Door Lock Actuator (DLA) did you replace? I went out again, it worked every time. Maybe I need to just exercise the passenger door more often

Intermittent unlocking problems is due to a bad general module. If the unlocking problem was permanent then replace the actuator. If you do need to replace the actuator always replace with a brand new one. Do not use a used one because if the high failure rate and you really donít want to be doing the job twice!

It's not a job you want to do twice but once you've done it, you know you can do it again. I got a great price on a low mileage used unit compared to a new BMW branded part - and of course, it works beautifully so it was the problem.

My passenger side door fails to unlock from time to time, and it has been doing this for years. It is much more likely to work when it is warm, and less likely to work when it is cold. Mostly it works so I have not tried to fix it.
