How a burglar can make a copy of your door key, from a Facebook picture

Martin Appel | July 3, 2015
Place a key on the table and bring out the smartphone camera. It clicks and the screen shows a razor-sharp photo of the key. The photo is all you need to print a perfect copy of the key.

6. It takes several prints and we have to whet it a bit as well. When everything is done we put it in the lock, and like a miracle - it actually opens.

The tools we used:

  • A common smartphone or a camera to take the photo.
  • The free software Paint (included in Windows) to crop the picture; Inkscape to convert it to a format that the 3D software can use.
  • 3D software 360 Fusion. It costs 2,500 SEK (USD 280) per year, but is also available in a free test version.
  • 3D printer Makerbot Replicator for around 30,000 SEK (USD 3,400). A cheaper model would have been just as good.
  • Plastic material to create the key. The cost is next to nothing.
