Toool’s DEF CON lockpicking class helps beginners find the right challenge

In a post on r/lockpicking titled “DEFCON Noob,” a beginner wrote that TOOOL’s intro lock-picking course at DEF CON helped identify the right level of challenge, then added that they picked up one of TOOOL’s “Necessary 9” kits. One of the first real lessons in locksport is that progress is not just about buying more tools; it is about choosing a lock that teaches the next skill.

Why the right lock matters more than the biggest toolkit

Beginners often make the same mistake from opposite directions. A lock that opens too easily can hide weak tension control and sloppy feedback reading, while a lock that is too hard can feel impossible long before the picker has learned how pins, keyways, and security features actually behave. The right practice target is the one that stretches the skill you are working on without overwhelming you.

The DEF CON class works as a filter for deciding what to practice next, which is often the harder part of learning than the picking itself.

What TOOOL brings to DEF CON

TOOOL, The Open Organisation Of Lockpickers, is a 501(c)(3) nonprofit in the United States devoted to advancing public knowledge of locks and lock picking through teaching, research, and competition. The group sponsors and organizes public education initiatives and often runs hands-on workshops at conferences and conventions around the world. At DEF CON, that educational model fits naturally into the conference’s village culture, where lockpicking sits alongside other hands-on spaces such as Biohacking and Crypto & Privacy.

TOOOL uses a full “Lockpick Village” presentation at larger security conventions and professional events, and keeps a separate “Lockpicking” presentation in its slide-deck lineup. For newcomers, one version frames the broader village, while the other goes straight at the craft itself.

A simple framework for matching challenge to skill

The most useful thing in the “DEFCON Noob” post is not the kit purchase. It is the reminder that the next lock should match the next lesson. In practice, that means treating your target as a training tool, not a trophy.

• If you are learning tension, start with something that gives clear, repeatable feedback rather than one that fights you at every turn.

• If a lock opens almost immediately, it may be too trivial to teach much. Move up to a tougher practice target before you build bad habits.

• If you cannot feel pins or tell what the core is doing, the lock may be beyond your current stage. Step back to something simpler and rebuild the basics.

• If raking is still the main way you are getting openings, that can be useful early on, but single-pin picking becomes the better teacher once you need to read individual feedback.

• If standard pins no longer give enough resistance, security pins and more complex keyways can create the next useful hurdle.

That progression, from clear practice lock to cutaway, from standard pins to security pins, is the same logic behind a good intro class.

The classroom model still shapes the hobby

TOOOL presents an introductory course at every Eastern US Meetup with hands-on instruction from experts. A short class can give a beginner the vocabulary for tension, feedback, and progression, and that vocabulary makes later practice far less random.

TOOOL was founded in the Netherlands in 2002, and a LinkedIn profile describes it as the oldest lockpicking group in the world after SSD e.V. That long public-facing history helps explain why the group’s beginner material is so often paired with starter kits like the Necessary 9.

The real milestone is learning how to judge the lock in front of you, whether it comes from the kit or the booth at DEF CON in Las Vegas, Nevada.
