Does it use the screws with the notches around the outside, or the triwing? The site store had stuff for opening both and there's even a coupon right now.

no it has like a square type screw

Ok, there are security bit sets with a bunch of types, but the square one is called a Robertson. If you have a random metal shaft scrap lying around and a file, you could file the end into the shape you need and then bend the other end into an L so you can get some leverage. I made a triangular tool like that once for opening up Happy Meal type things.

Here's some guy making a tool out of some allen wrenches for a bonkers security screw.
