Step 1
Think about how the door locks from the inside. You need to do the opposite to get it unlocked from the outside.
-
Step 2
Insert a small screwdriver into the lock and turn it, if the bathroom lock is the type where you turn the thumb piece to lock it. When picking the lock from the outside, turn the screwdriver the opposite direction of the way you would turn it to lock it from inside.
-
Step 3
Put a nail into the lock and push if the type of lock on your bathroom door is a push button lock, instead of one that you turn.
-
Step 4
Try using a straightened paper clip or a straightened clothes hanger if you do not have a nail thin enough to fit into the lock.
-
Step 5
Turn the knob of the door at the same time as you are pushing in on the lock and the door should open.
