Mortise lock measurement
A quick learner from Salisbury, Md. says:

It looks like the 82-034 will work on my sliding patio door. Will I need to change the mortise lock and if so, how do I measure the lock? The 82-218 looks like the right one. Measurement from the center of the screws is 3 11/16 inches. Also, if the locking handle turns out not to work on my door, can I return it?

Thanks for posting! You're already on the right track. If the screw hole distance matches our 82-218, it's probably a good bet. If you're still uncertain, you could always remove it from the door and compare its style to ours.
Take a look at this tutorial video on the proper method of replacement for the 82-218, as well. It may come in handy.
You can indeed return the hardware if it does not work. Take a look at our Return/Exchange Policy for more information.
