I recently came across a blowout on my rear passenger tire and when attempting to remove it I was unable to loosen the lock nut. It has a special key that is used to remove it, but mine appears to be stripped. The shop was eventually able to get it off but the key is completely shot. I would like to find a replacement for this key so I can remove the other three and replace them with regular lug nuts. Any ideas where I can find one of these replacements???
