Trying to determine if I can use a key lock

A quick learner from San Clemente, CA says:
I am seeking to make this door lockable from the outside with a key. It is a Casita that I have gym equipment and other items and want to lock it when I leave. I have had others look at it and they cannot make it work. Would one of your locks added to this work for me to lock it from the outside?

Hello,
It looks like your outside pull has holes that you can punch out to install a key lock. Follow the video below to see the best way to complete this process. If your outside handle is flat like the one in the video, you'll want to use the 82-315 key lock. If it has a raised portion where the lock would go, you'll want to use the 82-310. Thank you!
