Let me start off in saying I am very new to ST. I have 3 Kwikset 910 Locks in my home. I have Lock Manager installed and I was able to set user codes for the first lock. When I set the codes for the second lock they are gray instead of blue. I got a message that said connection failed.
Welcome to SmartThings. If you haven’t already, I’d install the latest SmartApp. You can find the instructions below. If you run into any issues with the install or setting your locks after that, post your questions in that thread. Good luck.
