E90 330 won't unlock! HELP!

Viral · 07-06-2013, 10:58 AM

Ok, this morning when I went o my car the doers wouldn't unlock.

When I press and hold the unlock feature on the key, the windows will roll down. When I lock/unlock the car, the lights flash like normal. When I press the unlock button on the dash, nothing happens.

What could this be? This really sucks because I have to climb in and out of the car throughout the window just to drive the car.

Any help is greatly appreciated!!!!

Use the key hidden in the key fob. My 330i did the same - but only once so far....

Check your fuses. Could be that simple.

It is a widespread defect on early e90. The door handle does nothing when activated from the inside, too. You have to open the door and replace something (don't remember the exact details, was done under CPO for me).

Try charging your battery. Invest in something like this http://www.harborfreight.com/automot...ter-66783.html

It is the fuse. I think the amp had to be changed from 15 to 20. Mine was done at the dealer and they changed the door lock actuators. I'm not sure if it was all 4 doors or front 2. But I exited out the window at the dealer to make it look dramatic. It's a same day fix.
