This Revolving Ring Keeps Your Keys And Saves Your Fingernails

Nothing Apple announced on Tuesday has as much life-changing potential as this revolving keyring does. It’s apparently based on a clever design from the late 1800s that was either lost to time, or confiscated by aliens to slow mankind’s progress. Either way, it’s back, and ready to save your fingernails every time you need to remove a key.


Hit This Magnetic Bullseye And You'll Never Misplace Your Keys Again

Are you prone to losing your keys more often than you’d like to admit? You just need to settle on a specific place to put them every time you get home. And to make this routine enjoyable enough so that it becomes a habit, trying to hit this magnetic bullseye when you get home every night sounds entertaining enough.


An Ultra Minimal Keychain Born From Recycled Bike Chains

It doesn’t matter how ultra-thin your wallet is, your pant pockets will still be overflowing if you’re cramming a huge set of keys in there. But even if you move everything onto a single ring, there’s still no way your current set of keys will get as compact as the TIK keychain.


Neat Trick Instantly Turns Happy Songs Into Sad Songs And Vice Versa

Here’s a fun little musical experiment from The Gregory Brothers. They flipped major and minor keys in popular songs to transform previously happy songs into sad ones and turn old depressing sad songs into happy ones. It sends your brain in a tizzy when you hear the words of songs you recognise but see them in a whole new light.


How To Pick A Lock Using Nothing But Hairpins

You can learn the basics of lock picking from a GIF, but for a more nuanced look at the techniques required to actually get a lock open without the key, check out NightHawkInLight’s latest tutorial where he uses nothing but a pair of strategically bent hairpins in the process.


A Key You Can Photograph Is A Key That Can Be Copied

If you take a picture of a car or house key, could you use that picture to get a copy made? Yes — quite trivially, actually. I have a folder on my laptop that is filled with photos people have taken of their keys and put onto the internet. Every few weeks, I take some idle time and associate one of those keys to an address (lot of Googling, mostly) and then I decode the cuts in the key.


A Multipurpose Key That Will Unlock Your Inner MacGyver

In addition to opening doors, that set of keys in your pocket also serves as makeshift knives, prybars, and even ice scrapers. But why risk accidentally bending a key and losing access to your home when this key-sized multi-tool can do so much more?


An Emergency Lightning Cable That's No Bigger Than Your House Key

How To Harness Solar Energy To Make Your Own Post-Apocalyptic Keys

We all know the world’s going to end at some point, and maybe it’s not entirely “likely” to happen anytime soon — but better safe than sorry. So assuming you’ve already been working diligently on your underground, radiation-proof bunker, what’s going to happen when you need extra keys made with nary a (non-zombie) locksmith in sight?


Pistol Keys Were Once The Last Line Of Defence For Prison Guards

Long before prison guards started carrying tasers, tear gas and other non-lethal deterrents, they apparently relied on these cell door keys that also functioned as tiny one-shot pistols. They probably weren’t lethal, but there’s no doubt they packed enough of a punch to make an inmate very uncomfortable if they tried anything while a guard was unlocking their cell.
