Seat lock stuck problem

[dsinned_imp]

It won't go any further clockwise than the 1 o'clock position. It's stuck at 1 o'clock and won't turn to 5 o'clock. Therefore, I can't pull the seat latch any further down than its normal helmet holder position. Something is binding the key from turning further. So, I'm not sure if its the key lock or the latch under the seat that is stuck. I'll give it a few more tries following White Dog's suggestion, but I'm not optimistic.
