Wall Oven - Door won't open

My wife ran the self clean on our oven. Later when we went to use the oven we noticed that there was no power to it. I checked the breaker, which was tripped. When I reset the breaker it tripped again immediately. I cannot get the door open because the self-clean door lock is still engaged. I can’t get the door lock to release because as soon as I provide power to the oven the breaker trips. I am selling the house and close tomorrow. Does anyone have any ideas on how to get past this Catch 22?
