Andersen sliding door keyed lock for 200 series door

Quick Learner from Westminster, Md
My Andersen sliding door 200 series, looking from the outside,moving door is on the right and the door slides to the left. I pulled the inside unit off and it has 7442-2 and 7442-3 stamped on the inside. Do I need to purchase a right or left key assembly?

Do your locks look like our 82-316 and 82-317? If the operating panel, from the outside looking in, moves right to left to open, then you need the 82-317. Let me know if you have any other questions.
