Matt, is there some reason why you didn't bother asking a single locksmith
if they knew about this attack already before claiming it was 'new' in
your paper? Have you looked into the differences in actual costs of
production of the various ways of making locks more secure? Do you have
any information on how common various ways of breaking into locks are done
in practice?

I'm not arguing that security through obscurity is a good thing, just
pointing out that your claims of the importance of your publication are
being made mostly in ignorance.
