Certainteed casement window lock

Thanks for posting. I'm afraid we do not know any service technicians in your area. Based on your picture, our 38-036 may be a match, but it's hard to tell while it's still installed.

You likely won't find any number anywhere on your window that tells you what you need; the only way to find the best match is by comparing physical details. I recommend removing your undamaged lock from the window and carefully comparing its design and measurements to the pictures and information we have for the 38-036. Let me know how well they match up.

I don't know if you would need the 38-036S. It is only used in some cases. The shim is used if you don't want the handle to be recessed into the hole in the window frame. Looking at your photos it looks like your locks are recessed and should not need the shim.
