Nothing new to add, but my BMW key is a key within the fob. I can leave the electronic fob in the car and dive with the metal key part which will only unlock the door. I know from practical experience that it's impossible to get my car started without either the fob or having it towed, so no way would i ever trust an underwater case.
(I once had to do a 500mile round trip to get my spare key as even BMW was going to cut a hole in my trunk lid to get my key out of there).
