Sliding glass door handle lock

If the door is stuck in the locked position, then remove it it will be a little troublesome. Your first step is to see if you can get a flat-head screwdriver into the hole where that thumb lever went and try turning the mortise manually.

If that fails, then your only option may be to cut the mortise off. This is not a small project at all, since doors are designed specifically to prevent you from doing this (for obvious security reasons). I would highly advise contacting a local professional, like a locksmith, to come out and review the issue.

Sure thing, Larry. So, this handle style isn't something that we can supply. The good news is that looking at the internal mechanism, I feel very confident that you can use our 82-030 as a replacement.

You'll note right off the bat that our thumb lever isn't in the same position as yours. Rather than being mounted above the pull, it's right in the middle of it. However that won't make much of a difference in your case since the spindle that actually goes inside the mortise is still centered on your original. That means the contact point between handle and mortise is identical between your old set and our new 82-030, despite how different they may appear. 

Looking at your mortise, I would suggest the 82-239. Just make sure that the dimensions all match up.
