Totally going to get one of these when I get back home. It’s called a Keyport, and it’s awesome. Basically, they make a copy of the important part of your key (shown in the second picture; they call it a Blade), and you use the spring-loaded knobs to slide out the one you want. The third picture shows the accessory Blades that are made by Keyport. I’m probably going to get the LED light and possibly the bottle opener. The last photo is just to show the scale of the thing. It’s just so CLEAN and simple and perfect. Waaant.
