A jimmy-proof lock is often located on the inside of a door. A jimmy-proof lock gets its name from the fact that it cannot be accessed from the outer portion of the lock on the front of the door. This prevents someone from prying off the lock. A jimmy-proof lock is also easier to install than a deadbolt.
Start by inserting the closed "looped" side of one bobby pin into the bottom portion of the lock. Use the second bobby pin, broken in half, toward the top of the lock and move it back and forth. This motion should set the pins and cause the deadbolt to unlock.
