Slim Car Key Cover (Mini Cooper)

thingiverse

When I got the keys for my Mini Cooper, I saw that they're a giant circle. I assumed the wide circle was to house an antenna for the wireless functions. Nope. It's just an obnoxious piece of plastic that takes up all the space in your pocket. This thing is to replace that large plastic circle with something slim. (And colourful!) To install it, open up your keys as if you're changing the battery. (Take out the metal stick part of the key, and use it to lever off the back panel. Careful, it's easy to damage the panel. I think that's unavoidable though, due to the design.) Once the back panel is off, you should be able to slide off the C-shaped piece.
