A handy person from USA says:
Customer wants a keyed lock on outside, this is what he has. What do I need to buy and how do I install it? Never did this before. Thanks Mike

Looking at your photo I believe this is an Andersen door. Can you confirm? If so, I recommend our 82-317 Andersen Triceca keyed lock. You will need to drill out a hole for this key lock set, so be careful not to damage the door.
