More on "Lock Bumping"

I posted an article about a week or so ago about "lock bumping", a technique where a blank key and a hammer can be used to open almost any tumbler-based key lock. Engadget has up an in-depth article about what bumping is, why it works, and what really is worth worrying about. This week lays out the challenge. Next week will lay out exactly which locks are vulnerable and which ones on the market are not.

I must say, as a guy who loves physics but is not a physicist, this is fascinating stuff. And scary as anything.
