Although suggested below on the Keysmart page I bought, it is a screw with a different thread. It does not fit. Make sure you (sort of) check you're getting the right expansion set for the key you have. As you say, I don't know, but there is a thin thread (the original keysmart product I bought) and a course thread (this expansion kit) that was sent to me. I don't see anything on the product pages that says what you're buying, whether it's an expansion kit or an original key fob.
