A German engineer has revealed how to make 3D-printed 'bump keys' These devices can be used to break into popular pin tumbler design locks To make the key all that is needed is a picture of the lock and pin positions Two engineers claim to have devised a 3D printed ‘bump key’ that, with a bit of brute force, can do exactly that. Their device can apparently be used to open any conventional lock without having access to the real key used to open it.
