Every time i put the key next to the transponder the bike would start, but sitting on the bike it would not some of the time. I took the battery out and made the angle on the 3 bottom contacts to around 100 degrees and the same with the side contacts. AS the battery went back in it seemed to have a better contact and less movement. Since then the bike has had no issues. So i think it was just a case of poor contact with the battery.
