Some German engineers have revealed designs for 3D printing a “bump key” that they say can be used to break into common tumbler style locks. According to the engineers, using nothing but a photo of the lock and some software called Photobump, a working key can be created.
Bump keys are not anything really new, but the ability to produce a lock-specific bump key through 3D printing from a picture of a lock, well that’s pretty new. A bump key basically uses some force and some jarring of the lock to move the small pins in the tumbler into the correct position so that the lock will turn.
