A:AnswerI got one that matched closely to door knob I had, since this just replaces the deadbolt part of the door . It comes with spare keys also but you program it with a number then you can do keyless entry or use phone app to lock and unlock the deadbolt. Had mine a few months works great well worth the money
A:AnswerThat's the theory. There's an app you install, and then you'd connect that to Alexa or Google (we have Alexa). But we've had nothing but trouble with this feature, so I'd go with another brand, if I were you!
