Patio door lock - double lock

Home Owner from Dallas TX
I am in need of a replacement lock mechanism. I do not know brand of door. Can you use these pictures to assist? At longest part, looks like this is 10 1/8"

See our 82-239 Mortise Lock to start. Review the dimensions and see if you think this matches what you need.

I'm afraid I'm not sure what you mean. There's a number of dimensions to consider with these mortise locks. I've reproduced the dimensions of the 82-239 below.
