Hey there, I got a sliding glass door with this lock but no idea how to work it. Figure I'll need to replace it with a new one that I have the keys to... looks like I'll also need a keeper on the other side.
Can you recommend part #s?
Thank you!

Hello, thank you for posting,

It appears that your door may use the 82-239 mortise lock. Please review the dimensions below to confirm a good fit! For a new keeper, review the 82-249.

For a new handle set with keyed access, are you able to provide the distance between the installation holes on the door from center to center? Thank you!
