Realizing you have completely forgotten where your keys are is awful. Don't rush off to nail your keys to your hand just yet though, we already have the solution: The Zeus magnetic key holder fixes to your wall and then suspends your keys from the bottom using 3 hidden magnets.
Hang it on your wall and your keys will always be in the first place you look.
It's crazy how strong this magnet is! You can hang multiple sets of key chains on it and it'll never drop them!
