My E60 used to do this at the self serve car wash when I would rinse it with the spray wand. I have wash the F10 and keep the key in the garage several feet away. It has not beeped before but I didn't take chances. Interesting about leaving the key inside. I wondered the same thing about not being able to re-enter. I have enabled the setting that locks the doors automatically after a period of no motion. Wonder if that happens if it will allow me to unlock from the outside with key inside the car.
