Got a xtx same year same problem, have took mine apart lubed it and played with it. Have found with mine if you put the key all way in and put a little pressure to the opposite way as to what part ot the ignition part you want. I.e to turn on at 11 o'clock put pressure on to 5 o'clock. This works fine for me for now :-\
