I'm assuming its a torx screw.

No its five sided with a needle in the middle. Kind of like a security bit, problem is it is 5 sided, i had a guy look at it and he said it was a special order penta-drive or pentagon over the top bit...

Not sure about the special order thing... Mine came in a small tool kit I bought from autozone for around $10. Not sure on the exact size but I'll take a look at it later today

Security torx

I believe they are referred to as "tamper-resistant" screws.

I use pliers to unscrew them since they are not that tight

or with some finesse, you can drill down the center pin

I used a dremel tool with a cut off wheel to cut a slice in the head, and I use a regular screwdriver to remove them.

I have one of those wrenches in my garage. I bought it years ago to secure the headlights on my Maxima when people were stealing Maxima headlights for the xenons.

It should be a "tamper proof torx".
Pretty much a regular torx with a pin in the middle.
You can buy a set of tools to take them out.
I have some bits at work.

I got mine off (and on) with a vise-grip. If your patient and gentle this works.

I had an uncle who made a whole bunch of special tools back in the 40s and 50s, including a growler to fix armatures. If he didn't have a tool, he simply made it. No formal education, but this guy re-built wrecked Cessna 120s and 140s. He would convert the fabric covered wings to aluminum.

Guy franky was a genius, and he had a Harley dealership. Developed many 'fixes' for Harleys back then.

Glad to see that many of us have the ambition and drive to make our own tools. There are no problems, just solutions, as Confucius once say.
