Plastic security cases are often used to store DVDs, video games, and other valuable items. They are designed to be challenging to open, acting as a theft-proof mechanism. However, there are several methods to unlock these cases without causing damage. One common approach is to use magnets. By placing magnets on either side of the locking bar, you can manipulate the internal magnets within the case, sliding them into the unlocked position. Alternatively, screwdrivers can be used to access the lock tabs and manually unlock the case. For those without access to magnets or screwdrivers, a pry bar or hammer can be used, although this method requires more force and caution.

What You'll Learn
Using screwdrivers
If your plastic security case is a DVD case, you can use screwdrivers to open it. DVD cases have small internal locking mechanisms called lock tabs located along the edge of the case, about 2–3 inches (5.1–7.6 cm) down from the locking bar.
To open the case, you will need to use two screwdrivers. Stick them into both lock tabs through the small holes on the front and back of the case. Then, take a third screwdriver and use it to poke the red lock icon in the middle of the locking bar. With the screwdriver pressed against the plastic, slide the red lock to the right until it becomes a green unlocked icon.
Once the lock icon has been moved, remove all the screwdrivers. Hold the front of the case with one hand and the back with the other, and open the case from the locking bar. You should hear a click as the case unlocks.
If you are having trouble using multiple screwdrivers, ask a friend to help you. It is important to note that some display cases at stores are designed to be difficult to open as a security measure, and attempting to open them could result in legal consequences.

Using magnets
If you're trying to open a plastic security case, one method you can try is using magnets. This method is particularly useful for DVD cases, which often have a small internal magnet located to the left of the locking bar, keeping the DVD locked.
Firstly, place one magnet on the left, bottom side of the locking bar. Slide it around until you feel the magnets snap into place. If your DVD case is clear, you should be able to see the small magnets. If your magnets do not snap into place, try using stronger magnets.
Next, locate the second internal magnet, which is found to the right of the opening along the edge of the case. Place another magnet here and, with your index finger, slowly move both magnets at the same time. This will drag the internal magnets, moving the DVD case lock from the "locked" to the "unlocked" position. You should see a red security icon in the middle of the locking bar begin to move as you slide the magnets. Continue sliding until the icon is firmly in the "unlocked" position, indicated by a green colour.
Once the case is unlocked, grip the locking bar from both the front and back and gently pull the case apart, like opening a book.

With a pry-bar
If you want to open a plastic security case with a pry bar, there are a few options to consider. Firstly, it is important to choose a pry bar made from a softer material than the plastic case to avoid damaging it. Nylon pry bars are a good option as they are flexible, durable, and less likely to leave marks on the plastic. You can purchase nylon pry bars, also known as spudgers, in various sizes and shapes, such as the Fixinus 30-piece set or the Kaisi 20-piece set. These kits provide different sizes and angles to help you find the best fit for your specific case.
Alternatively, you can create your own DIY pry bar by using an old credit card or membership card. Cut the card in half at a 45-degree angle to create a simple, yet effective tool for prying open plastic cases without causing damage. If you prefer a thinner edge, you can cut the card with an X-acto knife at your desired angle. This method offers a free and readily available option, but it may not be as durable as the nylon spudgers.
Another DIY option is to use a guitar pick, which is typically made of nylon or plastic. The high-friction coating on guitar picks provides a good grip, and the material helps to avoid scratches on the plastic case. This method is useful for smaller cases, such as those for remote controls or electronic devices.
When using any of these methods, it is important to exercise caution and apply gentle force to avoid damaging the plastic security case or its internal components.

With a hammer
Using a hammer to open a plastic security case is a straightforward but forceful method. It is worth noting that this approach may damage the contents of the case, so caution is advised.
Firstly, identify the weakest point of the case, which is often the corners. Place the case on a flat, sturdy surface, and hold it steady with one hand. With a firm grip on the hammer, strike the corners of the case with a swift, forceful blow. The plastic should crack under the impact, and the case may even shatter, allowing access to the contents.
Alternatively, a more precise method involves using a screwdriver and a hammer. Place the tip of the screwdriver against the black piece at the bottom of the case and gently tap the screwdriver with the hammer to chisel away at the plastic. This method requires a steady hand and careful aim to avoid damaging the contents.
In some cases, a combination of these methods may be necessary. If the initial strike with the hammer does not create a large enough opening, further chiseling with the screwdriver and hammer can help to widen the gap and provide access.
It is important to prioritize safety when using a hammer to open a plastic security case. Wear protective gear, such as safety goggles and gloves, to shield yourself from any flying debris. Additionally, ensure that the area is clear of any bystanders to prevent accidental injury.

Using a chisel and grinder
First, place the plastic security case on a stable surface and use your foot to hold it in place. This provides stability and control during the process. Ensure you are wearing appropriate safety gear, including eye protection and gloves, to safeguard against any debris or sparks generated during grinding.
Next, position the grinder at the bottom edge of the plastic case. Firmly press the grinder against the plastic and activate it. Use a steady, controlled motion to cut through the plastic. Focus on creating a clean cut along the edge, aiming to avoid any unnecessary damage to the contents inside the case.
As you cut, periodically check your progress. Adjust your foot's position and the grinder's angle as needed to ensure a straight and effective cut. If necessary, use a chisel to pry open the case further. Place the chisel at the point where the plastic begins to give way, and gently apply force to widen the gap created by the grinder.
Once you have cut through a significant portion of the plastic, you can use the chisel more aggressively to pry the case open. Insert the chisel into the gap and carefully apply force to slowly open the case. If needed, alternate between the grinder and the chisel until you have created a large enough opening to remove the contents.
Finally, once the case is open wide enough, carefully reach inside and retrieve the contents. Ensure you dispose of any plastic shards or debris safely, being mindful of sharp edges.
