In this tutorial, we learn how to pick a door lock with a homemade tool. This tool is made with a hacksaw blade. First, take a locked door knob and try to open it. If you can't stick a pin in the bottom of the knob, then push the saw into the middle of the lock as you are turning it. Continue to do this in a fast motion, making sure not to slip and cut your hands. Within a few minutes, the door knob will come unlocked and you will be able to open the door and go into the other room!
