I have one of those on each wheel of my 1996 SC2. Can't

remove them since the seller has not included the key. Does anybody know what this key is called? Or any suggestions on how to remove them ? any special tool?

 

A quality tire store should be able to help.

 

Not stock as far as I know.

I'd simply ask the seller again. They probably just forgot, unless they are flipping the car and have no idea about it. Pull the back seats down and look in the crease that is made between the back of the back seats and the trunk area. All kinds of **** finds its way in there and can't be seen from above. The key might be in there..
