How to use the helmet lock

1. Open the lock body. Locate the locking body portion of the helmet lock, usually a rotatable device, and rotate the body to the unlocked position, making sure the lock is in an unlocked state.

2. Insert the key. Insert the key into the keyhole in the lock body, making sure that the key is fully inserted, touching the mechanism inside the lock.

3. Turn the key. Turn the key clockwise until you hear a "click" indicating that the lock is locked. At this point, the helmet lock is in a locked state, ensuring that the helmet is securely fastened.

4. Close the lock. After confirming that the helmet lock is locked, rotate the lock back to the closed position to hide the keyhole. This will prevent the key from being lost or stolen.

5. Finish using. When riding or storing your helmet, make sure the helmet lock is locked to prevent accidental slipping or bumping.
