One evening when I was getting out of my car I went to lock the door using the button and the thing poped out. I found the button and it is intact including the spring and little white nipple looking thing. (Sorry if this seems vauge it is the best I can describe it.) Inside the socket that the button goes in thers is a piece of metal that looks like this --^-- .(a spring or contact mabey?) My question is; do I have everything I need to put it back together, and witch way is that little piece metal supposed to face?
