Forgive me for shutgunning this at you, but I don't have any experience with these smart locks, I just know they exist. This is my Canadian amazon.ca page,
https://www.amazon.ca/smart-door-lock-phone-app/s
but if you are in the USA you'll get the 'dot com' version of the site and it will show most/all the same locks. What I do, unless you would prefer dealing with a local handyperson, maybe via Home Depot or something like that, is to begin looking at the specs and features, but I also read two full pages of the 'reviews', seen in the smallish blue print closer to the top of the page. There will be some that complain of a common problem with the engineering or with the software/app, in which case it invites aggravation and loss of confidence. But if you get a lock with thousands sold and the ratings in stars exceeds 4.5, you are sure to get a decent product. Then, once installed, you must avail yourself of the app on your phone and learn how to manage the lock.

I am sure you'll get more informed responses in time...I hope...
