Patio door handle/locks

A quick learner from Northbridge, MA says:
Just moved into a new house and would like to change my locks. The patio door has a key lovk so I've dismantled it, but the replacement I got at Home Depot does not quite fit. I have no idea what brand the door itself is, nor do I know what to look for. Help?

It's tough to tell based on just the inside pull, but take a look at our 82-080. I think this may be the type of handle set you have. Look it over and see what you think!

It's a double mortise lock mechanism. The door is 2 inches thick. Will this handle fit the bill?

The 82-080 can work with a double-hook mortise, but there's more that goes into it than just those two details. I recommend carefully going over our pictures, dimensions, and information to confirm whether this matches your existing hardware.
