The Open Organisation Of Lockpickers
Deviant's Lock Diagrams and Animations

This is a repository of the most up-to-date versions of Deviant's lock diagrams and animations. Seen in all of the TOOOL educational materials and slide decks, these files are all released under the Creative Commons license. You are free to use any of them for non-commercial purposes, as long as they are properly attributed and the same freedom for others is maintained in all derivative works.

Please note that these diagrams have evolved and developed over time. While Deviant is still proud of the older versions of his images, if you still have copies of legacy material they should all be replaced with the latest versions available here. Each image shown below in thumbnail form can be accessed in high resolution individually, or you can obtain the full set from the zip archive at the bottom of this page.

Lock Basics and Mechanical Operation

How pin tumblers are arranged and how locks operate (or fail to) with conventional keys

Introduction to Lockpicking

Overview of why lock picking is possible and the use of basic pick tools

Somewhat smaller versions of the "lifting with hook" animations are provided since these are far and away the most massive of Deviant's diagrams. Many computers cannot properly decode and render the full-resolution animated GIF images during playback.

If you encounter this difficulty, use the slightly smaller versions of those files in the links provided. They are still quite detailed and should more than adequately show all that you need to demonstrate.

Manipulation-Resistant Locks

Spool pins, mushroom pins, and other ways of increasing security

Diagrams of Bumping Attacks

Animations showing how snapping guns and bump keys work

Key Impressioning

Many detailed, step-by-step diagrams and animations detailing the process of key impressioning

Master Keying and other Miscellaneous Matters

Diagrams that do not fall into a specific category

Master Diagrams

These two PSD files are the master copies that I use to produce all of the above images and more. If you want to make your own diagrams and animations, you are free to use these as a base. Absolutely all elements are independently rendered on their own distinct layers for easy editing. Pixel resolutions are particularly high for the best clarity possible.

Full Archive

A zip file containing all of the diagrams and animations seen above. It's just shy of 100 MB in size.


Thank you to all who share knowledge openly and responsibly. I look forward to seeing new generations of competitive lockpickers and dedicated hobbyists who study locks and encourage others to better understand them. If you find these images and animations particularly useful, or if you use them in a presentation of your own, please feel free to shoot me an email or a tweet to let me know.
