Childlock was on in my car, and my brother jerked the silver handle back so hard trying to open it that it loosened and now the door does not open from the inside. From the outside it works fine, but on the inside the handle jiggles loosely and does not work. Is there anything I can do to fix this, or will I have to bring it to a mechanic. If I need to get it professional fixed, how much will it set me back.

 

you can fix it yourself. take off the door trim on the interior and look around too see what happened if you need a reference pop off the other door to look at and see if theres a difference. its probably a metter of tightening something.
