For anyone having issues with security torx there is a simple solution if you have standard torx bits. Just take a small screwdriver or a nail in a pair of vice grips, etc, and wedge inside the security torx against the pin and push on it. The pins will snap off and now you can use standard torx. I did this to every 360 controller I ever owned as I tended to replace thumbsticks once or twice a year and I never bothered to get security bits because it took all of a second per screw to snap the pins off.
