Mortise lock replacement

A quick learner from New York says:
Hi can you suggest a replacement mortise lock for our patio door?

Here is a photo of it . It's 3 1/4" high And 1/2" wide The screws are 4" apart. Do we have to replace the part on the door jam opposite it also?

Thank you

Thanks for posting! Please take a look at our 82-218 Mortise lock. Do you think this would work for you? Make sure to compare all the dimensions.

As for the keeper, it isn't necessary to replace it at the same time, but if you were interested take a look at our 89-020.

You may also want to look at our 82-035 patio door handle set and our 82-309 key lock set.
