I can't open the rear door. It looks like the latch is broken.
If the latch is broken then that will definitely make the door not open correctly. The most common failure on this vehicle though is the door handle breaking inside of the door. If the door will not open then the door panel must be removed and the latch released from inside of the door. If that does not work then a mechanic would typically need to drill out the latch lock to get it to release and then replace the latch assembly.
