Inside the latch on the same shaft is a latch wheel, it has teeth similar but square edged as the teeth you see on the outside of the latch.
The door has a latch pawl that engages the hidden teeth and a separate lock pawl.
The latch pawl wears along with the latch wheel which puts it out of synch with the lock pawl.
You can remove the latch and grind some clearance into the lock pawl to correct the problem.
I bought a truck with a set of repro door latches installed and they seem to work fine.

Fortunately that is not always the problem as you seem to suggest. I always try the easiest solution before digging deeper into repairs. Moving a striker plate 1/16 of an inch is not a big deal compared to disassembling a door and removing the latch mechanism. That is why I always suggest it first. I asked him to let us know how that goes and if it doesn't work then is the time to dig deeper....
