Key has no use it's basically a major wow factor everyone who sees it is totally amazed they could care less about the x5 interior or anything about the truck everyone just wants to see the key lol , it's for techies !!!! Truly the x5 don't need a key it stays in your pocket and you never touch it so it's not needed BUT I love this thing and being available on the x5 I would have paid double for it
