Could be a bad fob, or antenna or tssm. Is the fob in a pocket with a bunch of other metal keys?All by it's lonesome in my coat left pocket. Only a metal zipper in the pocket. I will go out with the other fob and test both out of the jacket and in the jacket. Bike has done this from new. Anttena and all that crap is in place in the caddy. I'll report back. Also, I will see how far away the fob will work. If I move the bike around too much, even at 8' with the fob zipped up in the coat it won't start. I need to be beside it to deactivate it so it will start.
