How to remove security screws?

The key to removing security screws lies in the precise matching of tools to the screw head types. For instance, to handle a security Torx screw with a central pin, one must use a corresponding hollow Torx bit to engage it; whereas for a snake-eye double-hole screw, a spanner bit is required to accurately fit into the round holes, allowing counterclockwise rotation for removal.
