Bump key vulnerabilities in everyday locks

September 24, 2006

How pin and tumbler locks and keys work

In the time honored tradition of The MIT Guide to Lockpicking, engadget has published a two part series on bump keys and locks that are vulnerable to them.

Read part 1 here and part 2 here.

As with all security related matters, the best security comes from security-in-depth. It’d be a great idea to replace any affected locks with non-bumpables such as those mentioned in the article, but it’s also a great idea to have other security measures in place (external security cameras, fencing, an alarm system, a big mean attack dog, etc.). The more critical the thing to be protected, the more layers of security one should use.

Now go forth and lose sleep over all of your tumbler locks.
