    Hi. Yesterday I was recharging the battery and after put it on again and connect the cables run the bike with no problems( I had an issue with startitg, thats why recharged the battery), turn off the bike and after a while I've tried to start it again, but there was a red light flashing on top of TFT display, and doesn't turn on. The key was in my pocket. I tried several times with turning of and on the switch, the red light is flashing. I succeed to turn on and start the bike after several attempts.
    This happened to me for the second time( I own the bike from 1 mounth only) Is enybody have expirienced such a problems? Thank you.

    I keep the keyfob in my left trouser pocket when riding and it's very reliable if I'm sat on the bike or stood on the left side. It's not so reliable if I'm stood on the right or a couple of feet away.

    When I'm working on my bike I often find I need to leave the keyfob on the seat or top of the tank.

    It might be worth changing the battery in the keyfob as that can also cause problems due to a weak signal.

    If I have to charge the battery (very rarely), I don't disconnect it from the bike, just clip charging leads onto it in situ, or connect via the Hella socket forward of the tank.

    I'm having the same fits with the key fob.  Changed the battery in it and still having issues with the bike failing to unlock.  There seems to be some validity to the "cold temperature" issue as I have experienced it myself.  I've had to go so far as to remove the seat and set the fob practically on the sensor to get the bike to pick it up.

    Keyless ignition, a solution still searching for a problem.

    I love the keyless ignition on our SUVs, but don't really think I need the headache that the fobs on these newer Tigers seem to have. :164:

    I've changed the battery of the fob and did that described procedure. It's really strange decision of Triumph engineers with those moving contacts  :087:
    Hope, that the problem is fixed.

    The keyless ignition system and keyfobs are designed and built by Pektron who are 'specialist' automotive electronics designers and make ECUs and entry systems for many major manufacturers. But that doesn't mean they don't have their faults.

    The contacts under the battery are not 'moving' because they wrap-around the PCB to mate with gold plated circuit traces on both sides. They're also sprung to (hopefully) maintain a decent contact. I can't see why not to solder these though. The gold plating keeps tarnishing to a minimum and reduces contact resistance, but if the mating part is not gold plated or is not held in tight contact then problems can arise. Also any dirt ingress can easily cause problems. Looking closely at the design I'd be more wary about the single-point contact for the +ve terminal, but it does at least have some spring to it so should be held under pressure to ensure a firm contact when the case is assembled.

    The following images from their FCC filing shows what the keyfobs look like inside, so you can see how the contacts are arranged:-

    Neither do I. Đ¢his is a prerequisite for problems! My opinion.
    Thanks for the pictures :028:

    You need to carefully solider both contacts coming down from battery. My key was disconnecting randomly, after I solidered fixed the 2 (square) contacts. All problems went away
