I've have been in lurker mode, but really have enjoyed following you. But your failure w/ the keyless ignition has my attention. My wife and I are in our first month of a similar journey - currently camping in So Cal before crossing into Mexico at Tecate. Goal is Ushuaia in about a year from now. And ... I have a 2017 GSA with keyless ignition, and it is the one bell/whistle I would gladly do without, and was nervous about even before reading about your failure. I am curious what part they replace - and if it is something maybe I should pick up as an emergency spare. I know on the F800's, even w/o keyless, the ring antenna that sensed the key was a big issue and many people took to riding with a spare. I would do similar if I knew what spare was needed - so please keep us posted. Planning to head across the border in a day or two. Good luck!
