I purchased remote start/alarm from Auto Page. It has been over a year. The screws have come out of the key fob and the fob breaks into 2 pieces, exposing the electronics. I have looked all over to find matching screws and cannot. Can you please tell me the size of these screws and a suggestion on where they can be purchased. The back of the fob says XT-74 LCD, FCC ID H50TR30.
