Lock Cylinder for Sliding Door

Thanks for posting. I can't tell you what make this door is; however, as is often the case with sliding glass door parts, this is a generic handle set used by a number of different brands. See our 82-086. This handle set will work with an 82-310 Key Cylinder. The guide below goes into some detail about how to replace the cylinder. Let me know if you have any questions.

Great! I'm glad to hear that the 82-310 matched.

We do sell key blanks for this key cylinder, yes. See our 82-322.
