I can't believe you admitted not knowing about the Triumph on/off switch on the FOB. How obvious?
Just messing with you. I found out the same way you did and it was embarrassing - involving a woman I had just started dating having to drive me 1.5 hours home (and back for her) because I couldn't figure out why the bike was dead. Returned with trailer next day and figured it out after getting back home. She never found out it was my ignorance
Yeah, why the he11 would I need to turn that off?
I think you're going to have to carry it in your pocket. You should have gotten keys- they also allow you to start the bike when placed temporarily near the sensor on the back rear fender (you probably have already heard).
My FOB, and many other's, has poor battery connection which gives off a "FOB out of range" warning. Worst case it won't start. You may as well look that up for discussions on shims, etc. Without the spare key, I'm not sure the fob will work dead when placed near the sensor like a key (could be wrong). If I were you, I'd turn off the FOB and see.
Always carry a spare battery and a bit to open the FOB. I carry a 1/16th CR-V taped to the spare battery, which works.
