Need help patio door handle

A quick learner from USA says:
The locking part of this handle has been missing since I bought the house. Can't find a new one. Not many numbers on the door or handle the only part number I see is the sgd-30 on the gold sticker. Any help will be appreciated

I'm not sure if we can help replace this handle set. You have a Thermal Break patio door, which is a little thicker than normal. It makes it difficult to find anything that can work comfortably. That said, take a look at our 82-002K and compare it to what you have now. Alternatively, you might need to install a surface mounted patio door handle and lock like the 82-005 and 82-306. Take a look at the parts suggested and see what you think.
