Wheel key/socket question

I bought my car with team dynamics racing wheels on it. And did not get the key for the lugs. I sent an email to the manufacture asking if I could purchase one from them. Any idea who else I could get one from local or online if they dont get back to me?

Here is a quick picture of the style of lug on there. Do they make them in different sizes, or would that one work?

Well I found a tool. Guess I could have searched the site first. Ill buy it and hope it works.

Might as well get these with a tool. The lugs have the same dimmensions as the other brand "where they only work with their lugs".
