If you're the hopelessly paranoid sort who identifies with Mel Gibson's character in Conspiracy Theory, a New York cabbie who barricades himself at home with a phalanx of deadbolts, you'll love the KwikSet Smartkey. The secret to this formidable piece of security is its "un-bumpable" technology, a "side locking bar" that bypasses the traditional pins-and-tumblers system that just seems too easy to pick if you've watched enough CSI episodes. (Wikipedia has more on this.) If that's not enough peace of mind for you, there's an option to self-program any key for the system by using a small learning tool that re-keys the lock, thus rendering the old key useless if it goes missing. Apartment Therapy has a video that explains it all, lock, stock, and barrel.
