lock needed exterior anserson sliding patio dooe

Hello, thank you for posting,

Unfortunately we are not able to cross reference the Andersen # provided. To further review, are you able to show us the hardware (handles, internal lock) that the door currently uses to confirm the overall style? From there we can review to determine if we can provide the proper exterior lock for the door. Thank you! 

Thank you,

Are you able to show us a picture of the internal lock that the latch engages with? It appears you have the 82-043 latch. If so, take a look at the 82-316 or 82-317 exterior keyed lock. This assembly is compatible with the 82-037 mortise lock.
