I just went on shopee and ordered BMW key fob cases. They come in metal, plastic, or carbon fiber, and you just pop your keyfob in them and screw them closed. (it comes with a little screwdriver and screws). Got a white and colour change one, I thought they'd be super cheap, but they're surprisingly nice and held up well. Really popular in asia. Seems like there's less selection on amazon so you might have to dig a bit found some examples on amazonexample 1 example 2
