Even if you have a mind like a steel trap, sometimes your truck keys still sprout legs and run off to who-knows-where. Instead of tearing off the couch cushions, checking under the cabinets and turning the air blue, stash up to 10 keys in the KeySmart Pro. Not only does it keep them smartly organized, it comes with Tile Technology built in. If they ever disappear, you can fire up the free app on your smartphone and locate the KeySmart immediately. The reverse also works – if your phone goes missing, tap the button on your keys to make it ring. It’s one of the niftiest solutions we’ve seen to a common, cuss-causing problem!
