the latch should be adjustable. either the lock itself should be able to move up and down a few inches or the stud. Without seeing, its hard to tell, but try and use a big wrench and carefully turn the stud, some will actually move up / down /in /out as you turn it. if its solid and non-adjustable turn to the latch. loosen the 2-4 screws on the side of the door above and below the latch and slide up/down as needed. If it needs to move in/out you may have to shim or grind as needed.
