The Reflecting Key

Some dude who goes by the handle Josh invented a key called the reflecting key. It was a simple but effective hack. This is also called the smart key. The key itself has wafers. You can look inside to see the heights that the key needs to be to unlock the lock.

The key itself is hollowed out. There is an angle that shines up into the lock mechanism. You can take pictures of what you see in the key. There are six possible depths you need to measure. This works on Schlage locks, even the secure ones.
