Kwikset Smartkey System is Unbumpable, Can Learn New KeysS

The everyday front-door lock has had a bit of an overhaul with Kwikset's Smartkey system. First, it's designed to be unbumpable, so you can feel more secure when you leave your home unoccupied. What's bumping, you ask, innocently?

It's a way for nefarious types to defeat the lock by quickly shoving in a trick key, taking just seconds to do—apparently many normal locks are easy to defeat. Secondly, by using a special adaptor, you can actually teach the Smartkey lock to use a new key. Fancy using any old key, or changing keys once a week? Easypeasy. It won't make your home Fort Knox, by any means, but it adds a touch more security and may keep unwanted mothers-in-law at bay. [Apartmenttherapy]
