Check the battery, try jump starting it with another battery. If the battery voltage drops too low, i believe the alarm default is to disble the bike. (Greasy little criminals will cut battery cables to disarm the alarm) so although you may have enough power to operate the lights and alarm, it may be droppoing too low to start.

Put a new battery in the fob.....they are only good for about a two years usually.
