ok sounds like the cable or handle that opperates the latch is broken.if you can reach the latch from outside you should be able to see wear the cable attatches to the latch.you must try to use a screwdriver and pry to the side to opperate the latch,that should release the latch.once open then you can check the cable for proper opperation.or find what has broke.
