The Anker 3800 is a mechanical lock that has both traditional pins as well as magnetic sliders. Can it be opened without the key? This talk discusses how the lock works in a master keyed system and how it can possibly be defeated. It will cover decoding, picking and key duplication.


The Anker 3800 is a mechanical lock that has both traditional pins as well as magnetic sliders. It was designed by Japanese company MIWA and is sold in the Netherlands under the Anker brand. It is a high security lock that is often used in large master keyed systems.

I wondered: can it be opened without the key? I will present my adventures with the lock, having opened it up to see how it works, and several things I have tried to copy the key, pick the lock, decode the lock and find out what the master key looks like. The talk will include successes and failures and I will discuss designing 3D models, C&C work, electronics, Arduino programming, PCB design, and more.

The talk is aimed at people with an interest in lockpicking. No prior knowledge is necessary.

Walter Belgers is a hacker, having worked in IT security for all his life, the majority as a penetration tester and currently as a security officer at Philips. He has written a book on competitive lockpicking and he has been soldering since the 1970s but never before has he built a complete computer. He also likes to drift in a car and collect old computers.
