Check the tail light when the key is in accessory. Many bikes leave this on and all other electricals off, so if you are on the side of the road at night you have can be seen but not murder your battery if the bikes not running. (AKA the "don't hit my bike while I water the bushes" setting) or the "It's a good thing I'm not a helicopter pilot" light (ran outta gas)
Fork lock issue... I agree, just wiggle the bars a little while you wiggle your umm...key. usually works for me.
