This is a working sliding door made by Guardian. We can lock from inside. I am looking for keylock to lock the door from the outside. Appreciate your help what part number I need to buy.

Hello,
Take a look at our 82-310 key lock and the related installation video to assist you. Keep in mind that you won't need the housing shown in the video but the key lock is the same. Thank you!
