Have you ever needed to get into the bathroom and you can't get in because one of your siblings locked it?, If so definitely read his instructable. Right when I see that the door is locked I think "Jury-Rig it!," and so should you.
Most bathroom locks are very simple unlike the lock to your front door, most are just simple turning locks on the door knob. So if that's simple it must be pretty easy to get in once you have an idea. That's why I made this instructable, to show you the way I figured out how to get into a locked door. Although this only works on certain kinds of locks.
Step 1: What You Can Use
To get into a bathroom lock you can use almost anything including: change in your pocket (quarter, penny, nickle, or even a dime), or maybe a paperclip in your drawer or pocket. If you don't have any of that stuff then you can even use your belt!
