Ok the quick fix to get the door to close. The X5 lock will freeze after it rains and then the temps drop below freezing.

Once you get the car door open, inside the door jam on the door, you will notice a black oval rubber cap, remove that cap with a screwdriver, carefully. Once open, get a hair dryer and blow the hot/warm air into that hole, it will melt the frozen water along the cable and allow the door to latch. It works, but the problem will occur again given the conditions above. I keep a cheap hair dryer in the car for this reason during the winter.
