Please let me know why my latch isn't working. Do you need measurements?

I'm not sure why your latch isn't working. What exactly is the problem you're encountering? Is it the thumb latch that's broken, or the inside mortise lock itself? You can see our 82-218 for a replacement mortise lock, and our 82-106 for a possible thumb latch replacement. Let me know what you think!
