Buy replacement rods, pull out the damaged ones, and snap the new ones into place if any rods are broken. Stick them back into the holes or clips if they are just loose.
Look closely to see if any of these rods are popped out of the holes or clips that they are supposed to sit in or if they are bent or broken in some way. You will see several metal rods inside the door that attach to the locking and latching mechanisms.
