Antique brass levered separate deadbolt kit

Hello, when we bought our home, the former owner (in her 80's) did not leave us keys for the storm doors. This lock set up is antique brass and has a separate deadbolt. We think the door maker might be Larson but there isn't a sticker in the hinge. Any ideas on getting a replacement? We would like to keep the antique brass finish since it goes with other fixtures in the front. Thank you!
