I have a peachtree door that used to have a secondary latch that would keep the latch from unlocking. I actually had to move two latch turns in order to open the door. One of them broke off.
Do you have this handle set?

Your old Peachtree handle is no longer available, I'm afraid. You would need to use the more modern 82-005. Take note you will need to drill new mounting holes to match the 3-15/16" hole spacing.
