Lock Bumping

The lockpicking method demonstrated in the linked video, variously known as "lock bumping," "key bumping," and "bump keying," isn't new, but it was unknown to the general public (and even to many lockmiths) until 2005, when information about it began circulating on the Internet. Since that time, a plethora of how-to articles, videos, and even do-it-yourself bump key kits have appeared online, resulting in a spate of cautionary news coverage in early 2007.

Most of the items that are addressed on About.com's Urban Legends site are debunked as totally false or just generally misleading, but this is one of the rare ones that isn't.
