2003 X5, Key fobs stopped working approximately 5 months ago. Had to lock and unlock the doors with the actual key. However today the key would not work in the door lock. My husband got out of the car on the driver's side of the car and shut the door, I was about to get out as well when the doors immediately locked and activated the alarm. Thank goodness I was still in the car. None of the doors could be unlocked from the outside or with the central locking system button. When I pushed the central locking system button the alarm was activated, thank goodness my keys were with me inside the car, I just put it in the ignition and turned it off but I was still unable to unlock the car with the central locking system. I manually reached over and unlocked the Driver's door and my door and was able to drive the car home. We left the car in the garage with the windows down intending to drive the car to my mechanic on Monday (today is Sat.). I opened the driver's door to get my cell phone battery charger out of the cigarette lighter, as soon as I shut the door the car doors locked, automatically rolled up the windows and activated the alarm all while I stood there and watched unable to do anything. Now we can not unlock the car AT ALL!! The key doesn't work, we are afraid to mess with it in case the alarm goes off in our garage with no way to deactivate it. Of course this happened after the car dealers and mechanics closed for the day, AAARGH! Does anyone have any idea what to do. It appears that we will have to wait until Monday and have it towed but how will the mechanic get inside the car? How can I have it towed if we can't even get inside the car, which is in my garage?
