New Patio Door handle

A quick learner from Concord says:
he key broke off in the lock and the mortise lock fell into the door casing. We are trying to replace the handle with another one that locks and with a new mortise lock. The holes are spaced 3 11/16 inch apart.

Any help would be appreciated!!!

Sure, we should be able to help. See our 82-069 handle set and 82-310 key tumbler. I think these could work for you. As for the mortise, I can't be 100% sure what you have but I suspect it's our 82-218. This one has a bit of a reputation for falling into the door. See our video below on how you can prevent this from happening again.

82-032 is a more exact replacement, but I like the 82-069 better also. They should be totally interchangeable.
