Failed Key-Fob ended 7500km Trip short

That's correct. The smart key "lost" its identity with the ECU and therefore was being recognized by the bike. You are correct though, even with a "dead" smart-key the passive or alternate approach should work provided the key-fob and motorcycle are still paired. So if it was just a dead key-fob battery you should be able to start the bike using this method. Good catch.
 
No, i didnt misunderstand ...im saying if you keep the spare key under the seat then you may not be able to unlock the seat to get it out...but only if you misplace the original. I think your story was great...well said.
 
So sorry to hear what you went through. Very appreciative of your sharing the experience and the great suggestion so that the rest of us can avoid a terrible experience. Thank you!!
 
So sorry to hear, that this problem HAD to occur at the worst time!
 
Could you not just keep the spare key on the same key ring as the original key fob? What's the purpose of the foil? Also, that situation would have had me insanely livid.

1 - Yes, I suppose you could. Just a preference to not fill up the key ring but to each his own.
2 - The tin foil (aluminum foil) is to prevent the sensor (at the rear left panel) from inadvertently reading the RFID of the spare (standard) key; which would not be secure and render the bike operable by anyone who turned it on. More out of caution than anything.
3 - I was disappointed more than anything. A trip that was postponed in 2020 and and highly anticipated in 2021 was ruined by bad electronics. I guess I could yell at the sky gods or something but really it was about getting running again. My time in the military taught me to solve first, whinge second.

I posted this so that others may avoid a similar fate. If I help one person avoid such an situation, I'll be good.

Of note: I won't disclose the details but Triumph America, upon submission of my related expenses did offer me something as compensation for my troubles. Not a total reimbursement but something which is more than they were obligated to do. So kudos to them.

Update: The key-fob is ordered and is due in 3 weeks, so a trip to the dealer for pairing of the fob to bike and then I should be back to normal (with tin-foiled key stowed under the seat).

Also of note: I said "F@ck it" and we're going to do the trip again next year, come hell or high-water! Only this year our return trip will be through the New England states!! Yay!!!
