The Defendius Labyrinth Security Lock from ThinkGeek is “constructed of 100% titanium alloy [and] nothing less than a level forty-two spell of ultimate cutting will break the Defendius lock open.” Available now, priced at $49.99.

Really, just look at it: no one is getting out easily. You’ll have to guide the lock nib through the labyrinth before you can open to door. There is only one solution, so no cheating will help.
