I have a second key fob that came with my trike when I got it, but it is still in the original packaging and is not programmed. I have seen Fred Harmon's video on programming the key fob, but he does it on the two wheel bike. He mentions opening the left saddlebag and pressing the left saddlebag button as part of the process. How does this relate to my 2018 GL1800 CSC trike? Obviously I have a top trunk and a bottom trunk. Thank you in advance.
