The left passenger door lock has ceased to operate on my 2007 bmw 328i. It does not unlock with either the key fob or the main unlock switch. This is very dangerous if there were any kind of emergency involving this door needing to be opened.

Doors will not unlock using the key fob or central locking button. Locked doors will not open from interior of vehicle, no way to unlock the rear doors and front passenger door when they are locked. Only way to exit vehicle is through driver's door if manually unlocked with key. Passenger doors will not open and gas door will not open.

The bmw 3 series (mine included) identified by chassis designations e90, e91, e92, and e93 (all us models) have a known defect regarding automatic exterior mirror movement when unlocking the vehicle doors using the key fob. The mirror movement occurs regardless of which key fob is presented to unlock doors. A single keyfob unlock process can trigger innumerable exterior mirror positions. The unsuspecting driver who does not check both his/her driver and passenger side mirrors prior to driving the vehicle will be required to set the proper mirror positions while driving or leave them maladjusted until the next stop, impairing their ability to see vehicles adjacent or oncoming vehicles from the rear, including emergency vehicles. Bmw has issued a service bulletin regarding this defect. However, only cars with existing manufacturer warranties are repaired if this issue occurs. Ref bmw si b51 36 08 the problem has been linked to corrosion of mirror motor electrical connectors. It is also plausible that all electrical adjustment of the exterior mirrors would be rendered an impossibility if the problem escalates.

Electric door locks failed on all four doors with no symptoms prior to complete system failure. Key fob and central locking system button inside car would not unlock any door. Doors would not open by pulling on interior door latch handles. The only way to enter/exit vehicle was by using key on exterior driver's side door to unlock the door, or through the windows. This seems like an extremely dangerous single point egress failure that could result in unnecessary injury or loss of life in emergency situations. I replaced the blown 15a fuse (#57) with a 20a fuse per si b51 19 07 twice. First functional test by pressing the central lock system button resulted in the new fuse blowing immediately each time. Further troubleshooting and repair will be necessary to resolve issue (likely by replacing faulty electro/mechanical door latch/lock/actuator mechanism).

Using the key remote would only lock the driver's door. Then when using the key remote to unlock the door, the lights flash and the lock "clicks" but the driver's lock wouldn't unlock. I used the metal key in the key fob to manually unlock the door and tried it all over again. Same thing happened...key remote would lock only the driver's door lock...key remote to unlock would flash the lights but not unlock the door...requiring me to use the physical key in the driver's door to unlock the driver's door. Thinking that the car was not registering that the other three doors were not locked, I physically locked the doors while inside the car by depressing the locks on the top of each door. Bad idea! Nothing would work to unlock the car (with me inside!)...unlock button on the key remote...nope...lock/unlock button on the dash near the vents...nope....pull on the door handles of all the doors from the inside (multiple times)...nope. Ultimately, to get myself out of the car I had to roll down the driver's side window and used the physical key in the driver's door lock to manually unlock the drivers side door only.

Bmw 2007 328 xi door lock fuse #57 blew. None of the interior doors would open from the inside. I had to roll the window down from the driver side door, use the key fob to unlock the door from the outside. I then had to pull my kids from the car through the windows as the other three of the four doors would not open. Forget the toyota "accelerator"; this seems like a real safety issue.
