3D-printed 'bump keys' are a tech-savvy lockpicker's best friend

Printing a plastic replica of a key you’ve already got in your possession is a piece of cake, but the real trick for the curious and the criminal alike is figuring out how to print a key that’ll open locks without having an original key on hand. Wired spoke to a pair of lockpickers who did just that – with just a photo of a keyhole, some understanding of the lock’s depth and a bit of crafty purpose-built software called Photobump, security consultants Jos Weyers and Christian Holler can print so-called “bump keys” that allow them to jimmy open nearly any lock with just a bit of elbow grease.

Before 3D printing saves us it looks like it might sting us as well.
