"Spring" key organizer
Other key organizers exist, but this aims to push away from the DIY aesthetic and more for the classic Zippo lighter look, being more low-profile and pocket-friendly. By pressing the two side bottons, the keys would release partially and in a staggered pattern, so you can easily pick out the one you need. Click them back into place when you're done. The secondary buttons also allow for car lock functions to be programmed in.
