I was even more fascinated at all the other ingenious designs. Almost immediately I overpaid for a Medeco lock, just so I could play around with it. I was enthralled with the Medeco’s cleverness. The student and instructor had actually been talking about Medeco locks, a very well-known brand of high-security lock. I rushed home that afternoon and immediately began Googling. It’s design is very interesting but hasn’t changed since the 1950s and I would not recommend it today. and still one of the most common ( check my Lock Safari series). Medeco (short for Mechanical Development Company) was on one of the original high-security locks in the U.S. Just a few hours into the class I was actively wondering, “how do I protect myself from all the skills I’m learning?”Īt one point during the class a student asked the instructor something that I heard as, “What about ‘medco’ locks?” The instructor indicated he knew of them and used the term “high-security locks.” Wait – what? ‘High-security’ lock? Why had I never heard of a ‘high-security’ lock? Little did I or the instructor know, but the he had just sparked an interest that would border on an obsession for the next several years: high-security mechanical locks. We were learning all sorts of bypasses and defeats, and my mind almost immediately shifted to security.

I knew almost nothing other than my key worked every day when I got home. When I attended my first look defeat class – a really top-notch, five-day affair – I realized how little I knew about locks. Today I am going to offer you a primer on the fascinating world of high-security mechanical locks, the security benefits they offer, and what they can’t do for you. Even in the field of locksmithing where high-security locks are known, they are often misunderstood. Outside of a very few specialized fields high-security locks are almost totally unknown.
