But, from Airstream, they are rather expensive.
I will check out Home Depot as another source.
They didn't have them when I first looked, but I stumbled across this one recently. You may want to check multiple locations. The one nearest me has the worst selection and most out of stocks of any store I have been to, but it is on the way (and less than half the distance) to others.

You can get in with a coat hanger. I've had the practice to develop it into an art form.
This deadbolt attaches the screen door to the outer door itself, not the screen door to the frame. It allows you to use the screen door handle to move both doors at the same time. The screen door latches to the frame with a spring loaded roller.
