Of course, I do not encourage you to use this for illegal purposes. I figured this out due to bringing home DVDs from the library that did not get unlocked.
Step 1: Materials
The other item that can come in handy here is a screwdriver with a small regular tip. You can also use a knife, icepick, etc... as long as it has a tip small and sharp enough to grab the plastic.
Step 2: The Locking Bar
Step 3: Attaching the Magnets
1. Take the first magnet and place it in the upper right front corner of the DVD case. You may have to slide the magnet around a bit, but you should definitely feel it stick when you hit the right spot. You may also be able to hear the magnet in the locking bar click as it moves.
3. Take the second magnet and place it in the lower left corner on the back of the case. Again you may have to move it around slightly before you feel it catch,
Step 4: Opening the Lock
The quick and easy way to do this is to take a small screwdriver (or other tool) and use it to move the locking bar. Again, to the left for locking and to the right for unlocking.
If you have the magnets attached but are unable to move the locking bar, you may not have powerful enough magnets. I went through a couple sets before I found a pair that worked well. Weaker magnets like standard refrigerator magnets are NOT powerful enough to do the trick,
