I've recently had to look into buying a couple of decent padlocks to secure something, and did a fair amount of research to figure out which would be the best. To my surprise, it seems padlocks aren't all they're cracked up to be. Follow each link for some interesting information.

(He's not joking. I have a couple of Master brand combination padlocks, and tried his technique. It worked every time.)

If you’re like millions of Americans, you put a lot of trust in simple padlocks to secure your valuables.
Today we’re going to continue to break down the veil of security by showing you how easy it is to shim open a padlock with a coke can.
As far as lock security in general is concerned, try these two:
3. Lockpicking and the Internet.
Physical locks aren't very good. They keep the honest out, but any burglar worth his salt can pick the common door lock pretty quickly.
It used to be that most people didn't know this. Sure, we all watched television criminals and private detectives pick locks with an ease only found on television and thought it realistic, but somehow we still held onto the belief that our own locks kept us safe from intruders.
The Internet changed that.
4. ASSA CLIQ, MEDECO LOGIC, and SECURITY ENGINEERING: A Failure of Imagination.
We believe there are multiple failures in security engineering by some of the world's most respected lock manufacturers in conjunction with the deployment of the technology that involve electro-mechanical locks. Potential security vulnerabilities in these locks should cause every security officer and risk assessment team to re-evaluate individual facilities to determine their risk in the event of compromise and their inability to meet certain statutory requirements, such as Sarbanes Oxley or HIPAA.
In response to demonstrations and our disclosures about the bypass of Assa Cliq locks at Defcon 17, the product development manager of Assa in the U.S. told Wired Magazine that "From what I know of the CLIQ technology it can't be done ... And until I've seen it done, it can't be done."
We believe this statement typifies precisely the problem at Assa Abloy companies: a failure of imagination. It prompted our research and subsequent discovery of multiple vulnerabilities in Cliq, Logic, and NexGen locks. It is this attitude that will continue to allow us to break locks that are represented as the ultimate in security by these companies, and which often provide a false sense of security to the locksmiths and customers that rely upon these products.
All very thought-provoking stuff - and something to think about when you next buy or install any kind of lock. I'm certainly doing a lot more research right now before I invest in another padlock.
