I need Help! I removed the door handles, i loosen the screw to allow the door handle to come off. Then i tight the screw back to be able to open the door from inside while the door handle was off. But now when trying to put the door handle back i am not able to get it to work. The mechanism inside wont even move. I tried loosing the screw again to see if it moved but have had no luck. Does anyone have any idea of what i can do
