Is it necessary to deactivate the key fob if it is being stored away from the bike, with no communication with the bike?
They could also access your luggage compartments with one of those devices. When I’m on a trip staying in hotels I make sure and turn my fob off.There are devices that can read a keyfob and act as a transmitter to start the bike, so if your key is in the house and your bike is parked in the driveway (or car for that matter). it's possible to start.
I generally turn mine off when it's in the house
