Bike wouldn’t start 2020 GT

Went to start the Rocket after two weeks and it’s always on the Optimate charger to take it for a new TFT screen and it wouldn’t start ,checked battery terminals changed the key fob battery but still didn’t work held the fob by the left side rear mudguard and it started.
I had to get to the bike shop for the appointment so didn’t have time to do anything else,has anyone had similar and what’s the cure?TIA

Are you sure you have the FOB turned on? I turn mine off to save the battery and will from time to time forget to turn it back on until the bike acts like the FOB is missing.
