Need help 4 15/16" sliding glass door handle keyed lock

A home owner from Bloomfield, New Mexico says:
Hi. This is a 4 15/16" sliding glass door handle, with no numbers or markings on it to help identify the brand. We would like to either find an existing keyed door lock replacement for it, or figure out how to make this handle work somehow with a new key locking mechanism installed on/in it. We have looked at the big box stores near us and on Amazon, but are unable to find what we need for our type of door and handle. I'm hoping that you can help. Thank you for your time and assistance.

Hello,

Thanks for posting! Your handle set reminds me of our 82-005 Surface Mount Sliding Door Handle Assembly. To confirm that this is the right fit, carefully compare the other dimensions. Although, I am confident this the replacement you'll need. This handle set comes with the compatible keeper.

To convert this handle to one with a keyed lock, you'll also need to purchase the 82-306 Keyed Exterior Sliding Door Pull. This handle will fit the 4-15/16" installation hole spacing.
