Have you tried a default PIN. I seem to recall it's: 111111
My 2016 SG has only 5 digits, attached pic from owner manual as a suggestion, with the gaps between the numbers, may help ? Good luck.
The bike has to be physically at the dealer workshop to have a new fob coded to the bike. I have seen it done.
Tried 11111 on my bike. No luck. Alarm went off!
