This is the world's first carabiner key. It's a key that's also a teensy carabiner. How can they even make parts that small? Beats me, but you could ask God the same thing about your pecker! HAHA -- BURN, Needlepeen! No word on cost, but they are a real product you can order from Scott Amron at Amron Experimental (who also brought us keyring keys). But whatever you do, do NOT use them instead of actual climbing carabiners when you're out on the mountain, because they will break, and you will plummet to your death. And, even if by some miracle you don't die, you'll still be locked out of your house. Food for thought. "That's glue." IT'S BRAIN FOOD.
