Need replacement sliding door lock

Hi Jeff, thank you for posting,

Your lock resembles the 82-239 multi-point style. Please note if your lock uses a face plate, we also carry the 82-265 that has the same body, but with the face plate attached. Take a look to see how they compare to your original for the best fit.

If you need a new handle, you may be able to use a style like the 82-030 that has a 3-15/16" installation hole spacing from center to center. Let us know if you have any additional questions!
