Jeldwen Sliding Door (2014) - Exterior Lock Needed

A handy person from Chicago says:

Hello,

My mother had this door installed a few months ago and soon realized there is no keyed lock with it. Can you determine what lock assembly is needed from the attached photos? It appears to have a punch-out to install a mortise lock but, without having that tumbler I do not want to attack this thing.

Please let me know what to order.

Thank you in advance.

Best,
Nathan.

Hey, Nathan. Looks like you already have a mortise lock installed. The punch out is for the key cylinder, which could be our 82-310. Do its dimensions look about right? If you aren't comfortable knocking or drilling the punch out, you could contact a local locksmith for further assistance.
