But who has the time for that?  Well now, instead of making a trip to your local hardware store, you can now do it in the comfort of your home using services like KeysDuplicated.

Criminals are trying to figure out how to print a key that will open locks without having an original key on hand.

The team at Wired got to speak to some professional lock pickers who have found the solution. “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.” reports Engadget.
