I went to pick up my daughter from marching band practice on a Saturday afternoon. When I pulled into the parking lot at her high school and got out, I went to lock the doors. I heard a strange sound and noticed that the drivers doors were locked, the passengers doors were unlocked. The key fob would not work anymore on any of the doors but would work on the trunk. I got in the front passenger door and crawled over to the driver side and tried the door and it would not open from the inside. The central lock button also would not work. I crawled out and tried the drivers side door with the key. It did unlock with the key. None of the other doors would respond from the inside. After I got the drivers side door to unlock with the key, my key fob would work on the drivers side door only. …
BMW 325xi does not provide a manual door locking override for their cars. This lack of design makes their car a trap for all passengers when electronic system fails. One year after purchasing a car ( new ) BMW 325xi, the doors and window system failed in very dangerous way. With my baby and my wife on the back sit, when I try to exit the car the door system start shutting down, the doors and window system just would not open. The only one that open was the driver side one. After this incident it happened three more time. Once all four doors locked and I had to lean out the window and open the door with the manual key. The latest one was with my 7 month pregnant wife climbing out of the car through the front of the car. …
Tl* the contact owns a 2006 BMW 3 Series. While parked, the contact attempted to open the driver?s side door using the electronic key fob but the door would not open. The contact eventually opened the front driver?s side door with the handle and was able to enter the vehicle. The same failure occurred on all other doors. The vehicle was taken to the dealer for a diagnostic test. The technicians stated that the door actuators on all doors needed to be replaced. The vehicle was repaired. The approximate failure mileage was 50,700. Updated 05/31/12 the doors would not open from the outside or the inside due to the failure of the actuators. A mechanical override failed and the door handles would not work. The key only worked in the driver's door.
Door locks on 2006 BMW 330xi suddenly stopped functioning properly midway through the day and were unable to be unlocked. I was able to open the door with the embedded physical key in the fob but when I got in the car and tried operating the doors they again locked but were unable to be unlocked neither by the unlock button on the console, the fob or the door handle. The only way I was able to exit the car was to roll down the drivers side window, and use the emergency mechanical key to unlock it by extending my hand out the window. Since the driver's side door is the only door with a physical keylock, it was the only door that was able to open. For the remainder of the day, all 3 passengers had to climb out of their windows to exit.
Went to unlock doors in 2006 BMW 330i and there was a rapid clicking sound in the front passenger door. The power locks failed to respond afterwards and all doors remained locked. The fob, nor the internal unlock button would allow the doors to be unlocked and attempting to open the doors from the inside did not work either. Only the driver's door can be manually unlocked by physical key or by pulling the handle from the inside. An initial attempt has been made to fix the problem by replacing the fuse #57 with a 20a fuse over the original blown 15a fuse.
Can't recall the exact sequence of button pushing that resulted in my being locked inside the vehicle. Not even the double handle pull that usually releases the lock from the inside worked. Had to roll down the window and use manual key from the outside to unlock. Diagnosed as a blown fuse. Fuse was replaced. Now locks are intermittent again after 2 months of working OK. The car has had the actuator replaced before, now it appears to be broken again. Will not electrically lock or unlock now. This seams like a huge safety concern in the event of an accident.
BMW door locks randomly and automatically engaged. This is one week after a service performed at the dealer for an electrical issue. Locks would not disengage except manually with emergency key (from outside). Driver's door is the only door that will open - others are inoperable. Fuel filler cap will also not open. Have researched and found this is a common problem. This should be researched by BMW and remedied at no cost to the consumer - this is definitely an inconvenience and could be dangerous or potentially fatal.
The door locks on my car failed resulting in not being able to unlock any of the doors with the key fob. I can unlock the driver side door with the valet key. None of the other doors can be unlocked and can not even be opened from the inside. This is a safety issue with the heat in southern california recently someone getting locked inside their car could be in serious trouble. Not to mention the fact that if in an accident any passengers in my car would have been unable to get out because the door locks malfunctioned.
Failure of door lock actuators in 2006 BMW 330i. Inside lock/unlock button would not function, remote keyless entry would not unlock any doors, key would unlock driver front door, gas door could not open, no way to unlock/open passenger front/rear or driver rear doors even using inside handles. Children were in the car and had to exit either through the driver front door or through an open window. Serious safety issue preventing or delaying egress of passengers.
