And how do you delete the factory 123456 code? Did they think about that? I may return and get a different one. Have Installed many smart locks in my low voltage days, usually the expensive ones, and this is by far the most unnecessarily difficult setup I've done. I guess you get what you pay for..

3+ unlock button doesn't work. I accidently got it to pair to the app but I do t remember what I did and I can't get it to pair with the other users app, only mine. I can't believe there's steps missing.. instutction
