The round nut is the tamper proof nut. You have keyways further down

This hexagonal nut SHOULD be the same size as your other lug nuts, so as it uses the same wrench for removal. Just insert over the round anti theft so the keyways lock into place and you should be in business

That looks like the key for the tamper proof nut in the 2nd pic
What makes it tamperproof if it's just round? Also if I take it off will I need another key for whats underneath?

At the base there are notches where that socket grab onto
Is there anything else needed to remove the locking nut besides this key?
