Rear left side passenger door will not open from the outside

What is your question?

My husband was attempting to engage the child lock doors on my 2005 prius. He jimmied the lock and pulled it out so the door would not shut closed. He used a screw driver to help jimmy the lock back in place so the door shuts closed now. Now, current problem is the door will not open using the handle on the outside. We need to open it from the inside now in order to open the door. The child lock has been disengaged for the mean time. We are noice DIY repair-ers. Should I take the car to the shop to fix this or is it an easy fix?
