I really don’t understand why the i3 key is so big and bulky. Not only is it awkward to carry around in a pocket but it is the only car key I have ever had a regular problem with owing to the buttons being pressed while in my pocket. More than once I have gone out to my car to find it unlocked or the windows down! I would much prefer a small key, especially with the comfort access option as I don’t need to hold it. Even better, would be the option to have 1 key for more than one car so if I owned 2 BMWs I would not need two keys.
