Hello,

I'm trying to locate either a replacement lock or lock/handle set for my patio door. The first photo has some markings on it that I hope will lead to the manufacturer's name.

Let me know if you need more information and thanks!

Hello,

If the key lock is the problem, see the 82-310. If you're referring to the mortise lock in the center of the door, take a look and compare the 82-218 to your assembly. Thanks for posting!
