The locking bar is an indented rectangle located on the edge of your DVD, used to help you open the case. Use any household magnet, like from your fridge. If your DVD case is clear, you should be able to see the small magnets.
You only have to move the magnets about 1 inch (2. 5 cm) to the right. If your magnets do not unlock the case, try this again using stronger magnets.
Lock tabs are small, internal locking mechanisms located along the edge of the DVD case. Leave both screwdrivers inside the holes at the same time. You need both lock tabs pressed down at the same time to open the DVD. If you are having trouble using multiple screwdrivers, ask a friend for help.
You should hear a click as the DVD case unlocks.
