Physical keys and locks are one of the oldest security mechanisms still employed
today. In this talk, we will discuss how 3D printing keys enable attacks against many modern lock systems. We will describe projects researchers and hobbyists have done involving 3D printed keys, and present our own research on automating several of these attacks in order to demonstrate how easy they are to do. Ultimately, we hope to describe the current state of 3D printed keys, and their impact on the physical security systems we most often take for granted.
