OP, the key case sounds like a workaround for you.
If that does not excite you and you prefer not to have the window down function from your remote, ask your dealer if they can code your car to remove this feature. Its should be possible.
To be honest, I prefer the old way BMW did their trunks. They unlock but require me to lift. I don't need the trunk to pop up like a spring loaded clown.
