This a cool key but pretty ridiculous and useless. It’s known as the BMW display key. Besides looking cool and charging a hefty replacement fee, I have not found it all that useful. It’s also made of plastic and feels “cheap.” The BMW app can start the car from anywhere and provides two way feedback like this key. The app also provides the same vehicle info from a farther distance. This particular key/vehicle does have not have the self drive feature like the 7-series (this is from an X5). I’m not sure if that option is even available in Canada.
It also has to be charged! Granted, it does have wireless charging and the vehicle does too. It’s just annoying to charge yet another object.
