wire hangers, paperclips, bobby pins, ink cartridges, etc. To unlock a button-type privacy lock, take your tool (small screwdriver, paperclip, or other thin objects) and insert it into the hold as far as you can.
How do you break a privacy lock?
Use a screwdriver with a thin rod to unlock a twist-privacy bathroom lock. Insert a very thin screwdriver into the hole in the middle of the doorknob. Wiggle the screwdriver around until you hear the door unlock. You don't need to turn the doorknob while you are using the screwdriver.
