The Right Key (Which Key? in the UK version) is a puzzle in Professor Layton and the Diabolical Box.


Which key opens the door?

As you might expect, the key won't open the door if its shape won't let it pass through the keyhole. Use your stylus to fit keys to the lock.

Examine each key carefully and use your stylus to move the keys and find the one that fits on the lock.

At a glance, the ends of the keys look too intricate when compared with the simple shape of the keyhole.

Concentrate on finding a key with a shape that matches the structure of the lock.

Who's to say one end of a key is any better than the other?

Turn each key around and try inserting the part you'd normally call the grip.



That's right!

Did it take you a while to figure it out that the portion of the key resembling the grip was actually the part that fit the keyhole? Answers can be often in the most unlikely of the places.
