Improved Hyundai key fob egg for Tucson Santa Fe

I got a Hyundai Tucson and absolutely love it, but loathe the key fob. No built in physical key (not that you really need it), the thing is giant, and UGLY. Interestingly, there's very few other attempts at replacing this fob case, so I thought I'd give it a shot

There's a TON of extra room in the fob (and not nearly as easy to open as others I've had?) so I extracted the PCB and built a fob around it. I have slits so the natural flex of the plastic allows presses with a satisfying click. 

It retains all 4 buttons from the top (yours might not have the engine start) but I've also sunk so much time into this that I've decided I'm going to offer a paid version that excludes the engine start, as well as a version that has the side buttons, and another that has a space to store the physical key.
