Is there a way to change the handle to where you can lock it with a key. We have elderly and a ramp system to help them get into the house from the deck I think my door model is SDG

Sure, you should absolutely be able to install a key lock on this door. I can't see your outside handle in your photo, though, so I'm not sure exactly what it's compatible with. I'll just suggest an all new outside handle and key lock that should work for you. See our 82-044 handle and 82-315 key lock. The video below should also be a big help.
