2001 BMW X5 latches & locks problems

Front doors lock occupants inside of vehicle and cannot be opened from inside or outside. Occupants must crawl out of rear of vehicle to exit. Door locks appear to unlock, and handles pull, but there is no unlocking or release of the door latch.

Read that the BMW x5 had problems with it's door lock mechanism. I had experienced the locks not opening in the cold myself, and had seen several people at the dealership with the problem. During a ski trip to mountt snow vermont my door locks were slow to open. The passenger door wouldn't close at first. Then when pushed hard it closed. The door would not open with my passenger inside. She tried the door handle, from inside and I had tried it from outside. The door was unlocked, but would not open at all.
