OK. So where is the lock? Next to the one that is open? If so, the 'cabinet' isnot locked. Just something is stuck. Maybe bent. you should be able to remove that drawer and get to the rest of the latch system.
to the upper right of the open door. im pretty sure something got jarred. I was loading it and dropped it so something probably popped into lock. the lock is now depressed as if its in the lock position
