Replacing keyed door hardware on a sliding glass patio door

Question

I am looking to replace the locking portions, or maybe the entire handle/lock, for this door handle. I do not know the manufacturer of the door (or the hardware), which is 1" thick. The door was installed in 2006, but the company that installed the door is clueless about replacing the hardware (which they also installed). I have the measurements of the distance between the screws, but need to know which parts I need, a brand, and where is the best place to purchase these parts locally. I am also open to ordering them online, if I am sure they are the correct parts for my door.

I believe that the thumblatch might have some broken internal parts, and also although the key latch fits into the keeper, the door can still be moved, but not opened, when locked.

interior handle screw centers: 4 15/16"
mortise lock (fits inside doorframe)screw centers: 4 14/16"
exterior handle with lock: depth = 1", height = 4 3/8"
door thickness: 1"

Thanks for any information you can suggest.

Thanks for posting! It sounds like it could be the inside mortise lock that's giving you trouble. I recommend that you look at either our 82-211 or 82-214. If you want to just change the key cylinder, you can take a look at our 82-310.

I also recommend that you recheck your hole centers and door thickness. The handle set looks like our 82-035, but the screw hole centers are 3-15/16" apart, and for doors that are 1-5/8" thick.
