Need the locking mechanism replaced

Question

The locking mechanism is faulty. When you move the lever, the latch sometimes moves and sometimes does not. Using WD-40 on the part did not fix the problem and made it worse. The house was built in 1987. Can you provide a replacement part?

Take a look at our 82-218 mortise lock and 82-020 handle. These could be the parts you're looking for. See if they match up to yours.
