https://peertube.eqver.se/videos/watch/ad8ee470-9777-4c86-9dd4-1dbe95b49920 A DEF CON 30 talk on a new trend in the lock industry — adding movable elements to keys to prevent duplication. The presentation examines systems such as Mul-T-Lock, Abloy Protec 2, and Medeco M4, where this technology is used to block casting and 3D-printing of duplicates. The speaker reveals a discovered vulnerability and demonstrates practical bypass techniques using solid (one-piece) keys, as well as alternative approaches — from printing compliant mechanisms to embedding functional moving elements directly into the key.
