Lock on a Sliding Door

A quick learner from USA says:
I bought a lock to install in my sliding door. Part No. 82-303 . What I received was only the lock cylinder, but the door handle doesn't seem to have any sleeve or other mechanism to secure the cylinder in position. Is there something else I need in order to add a lock to my door?

There typically isn't anything else you need, but I believe the 82-303 is the improper key cylinder for your handle. That may be why you're running into problems. I believe that the 82-310 is what you want. If you look on the top of the 82-310 , you'll see it has a flat rectangular head. That goes in between the posts on the inside of your handle (they surround the hole), visible in your first picture. In some cases, it's necessary to open up the round hole a little with a rat tail file. The face of the 82-310 might need to stick out just a little out of the handle.

After taking a look at the handle the guy at Home Depot recommended the 82-303 as the part to order. (HD doesn't sell the part) But I see that they didn't look very closely. Thanks for your advice. That should solve my problem.
