keyed storm door

Looking at your photos, I can see that you have an old handle set that is no longer made. You will need to use a different style handle set and drill for the new mounting holes. 

But what substitute do you need to use? Well, it depends on a few things. If you door swings inward, then we recommend our 40-028. This one doesn't come with a key cylinder, however. If you storm door swings outward instead, then you should be able to use a push bottom handle set like the 40-034K, which does come with a key.
