Dave, there are also a variant of Bump Keys for car locks that are
called 'jigglers'.  They are sold for car repossession and locksmiths,
see for example:
http://www.lockpickshop.com/p-SJG-10.html

Yeah, for only $24.95 you can get a set that'll open many cars!
Legality of such locksmith tools of course varies by jurisdiction,
many of which require licensing to buy them, but in the Internet Age,
that doesn't look like much of an obstacle.

Let me urge people to read http://www.toool.nl/bumping.pdf , referenced
from a previous link.  For one thing, it's not a new attack; it's been
known for >50 years. It also explains in more detail how to do it, why
it works, and notes that there are some lock designs that are immune.
