Anyone had this happen?

G,day everyone
I managed to loose my key at a mates place the other nighte, somewhere between first and last drinks, came back with a spare the next day only to find it dose everything except start the bike!
Lights,blinkers ,horn, it all works , but no display on the guages and no start.
It was running perfect the day before, and allways has, the wires and fuses all test OK so I am at a loss to explain whats going on.
Any suggestions?
Cheers.
