Keyed patio door handle

Question

Hello,

I want to replace my existing non-keyed sliding patio door handle with a keyed one. I'd ideally like to avoid replacing the double latch keeper on the door frame, but those measurements are proving difficult to find. What sets do you offer that would match my existing screw holes as closely as possible?

Thank you!

Hello! It appears that your hole centers are just shy of 4" apart, so probably 3-15/16". This is a fairly common size for this kind of door.

With that in mind, and given the fact that your thumb lever is centered, I'd suggest our 83-030A handle set. This has a 3-15/16" hole spacing and a centered key lock. This should be fully compatible with your existing mortise.
