In most cities, people generally lock their doors before heading out on errands. There are very few places where it's safe to leave your door unlocked anymore.
Some folks even upgrade to highly secure locks to better protect their family and their valuables. But 3-D printing technology could change that.
An unintended side effect of the phenomenal 3-D printing technology is that parts and items are more easily customizable and available for a fraction of the previous costs. This means that burglars could have easy access to your home with 3-D printed "bump keys," and you would be none the wiser.
A pair of lock pickers and engineers, Jos Weyers and Christian Holler, have designed a 3-D printer software called Photobump and they claim that with just a picture of the keyhole they can create a bump key for locks that were previously labeled "unbumpable."
As a result, all anyone needs to open many locks previously considered “unbumpable” is a bit of software, a picture of the lock’s keyhole, and the keyhole’s depth, says Weyers, a competitive lock picker and security consultant. “You don’t need much more to make a bump key,” Weyers told an audience at the Hackers On Planet Earth conference, where he first hinted at the key printing software last month. “Basically, if I can see your keyhole, there’s an app for that.”
Take a look at Holler bumping an Abus E20 six pin security lock. His 3-D printed bump key is printed for an Ikon SK6 and filed to create carefully contorted blanks that regular key-milling machines can't make. It takes him less than 10 seconds to bump the lock.
