Small part or whole lock and which lock?

Quick Learner from St Louis, MO
The deadbolt spins. Is there a small part to replace or does the whole 3 pint lock need to be replaced? Which lock would it be?

Hello, thank you for posting,

Unfortunately we are not able to assist with a replacement or parts for multi-point mortise locks. You may need to contact the original manufacturer of the door for more information. I apologize that we cannot assist with your repair. Please let us know if you have any additional questions.
