My keys are locked in my trunk

My keys are locked in my trunk. A locksmith came to help by using an air jack to pry open my door and press the unlock button. But afterwards the car safety features prevented me from opening the trunk via the button. I come to find out he can't pick the lock on the trunk or do anything about it. How does a locksmith not know how to pick locks!? And then still had the audacity to try and make me pay for it.
