Modify a security bit
If you bought a security bit hoping to use it to open the VB
up, you've probably noticed that it's unable to reach down in the 4
deep holes. There is a new bit available with a longer neck that may
work, but I haven't heard of anyone trying it for sure on a VB yet. If
you already have one of the short bits, here's a method of modifying it
to work in the deep holes. You can also make the modified flat head
screwdriver, which is probably easier to do, but this works better as
far as ease of removing and tightening the screws.

Now you're going to use a grinder to grind the bit to a round cylinder
about the size of the tip

Then put it in a vice and use a dremel to make a notch for a flat head
screwdriver
Like this
Then you can drop the bit into the hole and use a standard flat head
screwdriver to loosen and tighten the screws
