which lock for patio door?

Question

Hello, I am trying to determine which key cylinder is needed for my patio door. I have attached pictures. I cannot locate identifying marks or the manufacturer's name or part number. The inside and outside of the door handle is 7 inches from the top to the bottom. The inside metal latch is 5.25 inches from the top to the bottom of the open metal. Is this enough information to determine a cylinder that will work for the patio door? Thank you very much

Thanks for contacting us. I believe our 82-310 can work as a key lock for this door.
