Replacement Part for Sliding Glass Door

Hey, Helen. This is a pretty common problem. Based on your description, the culprit could be one of two things: either the mortise lock is broken, or the thumb lever is broken.

An easy way to determine which is the case is to simply remove the handle from the door and look at the thumb lever tail. If it's in good condition (straight and whole, not twisted or broken) then there's a good chance that you just need a new mortise. To test it further, stick a screwdriver in the slot and turn it to try to flip the mortise hook manually. If it doesn't come out, then you found your problem.

Assuming that you end up needing a new mortise lock, and I think you will, then I recommend our 82-226. I am very confident that this will replace the original.

That would depend on what kind of space you have available. The 82-226 is compatible with a bunch of different keepers that are all in different sizes. You can stat with the 89-020, 89-021, and 89-021D to start with, as these are the most common choices. However you should keep in mind that there are more besides these three.

I'm sorry that we could not narrow it down further.

Assuming your door is the same as what's pictured at the start of this thread, then you may find the video below to be useful. This shows how to remove both the operating and stationary panels.

I can't really say with certainty without seeing your door. Once again assuming that it's the same design as shown in the original photos of this thread, then it is highly unlikely that the stationary door can't be removed. 

If your door is at all different, though, then we really will need clearer photos. You may also want to consider contacting a local professional to come out and do the job for you. Removing a patio door isn't an easy job and it's better to get help than to take chances.

I'm afraid those labels don't tell me much about the door itself, but I am familiar with some of the hardware I see used on it. Unless your door is a style I have not yet encountered, the instructional video shared above should be applicable to this project, as well.

If your door functions differently, or if you are unable to follow the steps used in our video, then you may want to seek the help of a local professional.

Unfortunately, we do not sell complete doors or door frames. My suggestion would be to contact the original manufacturer of the door for assistance.

You will need new glass panes for this door, unfortunately. I recommend contacting a local glass shop in your area to see if this is something they can help you with.
