We've all seen lockpicking explained on several security venues. You might even have tried it yourself. But what if you need to open a lock a number of times? Wouldn't it be great to have an opening technique that would supply you with a working key in the process? 
A method to do this has existed for quite some time, but until recently it has remained quite unknown. Some time ago impressioning locks got "re-invented" by the lockpick community and the skill evolved to the level now shown at several international championships. 

Unlike lockpicking, impressioning creates a fully working key for the lock which can be used to lock and unlock the cylinder at will. With practice, this technique can consistently open a lock in 10-15 minutes (and potentially faster)!

What is it? How does it work? What skill is involved? Why is it the most interesting way to open a lock? These questions, and more will be answered in this talk.

Jos Weyers (@josweyers) is a world-record holder in the field of lock impressioning and a mainstay at LockSport events around the world. A long-time member of TOOOL in the Netherlands and a key figure at the Hack42 hackerspace in Arnhem, Jos is the Vice-President of TOOOL.nl and helps to oversee that organization and the LockCon conference. Most people know him as the Dutch Kilt guy.
