So we had a keypad door lock that could be opened by using only a passcode. The things I love about the Assure 2 lock by Yale is the Bluetooth and app integration. I really like (and find it extremely handy) are the auto-lock and auto-unlock. I can set the door to lock after so much time, or if I forgot to lock it, I can do it from my phone. I also love that I can have the option to have the door unlock when I get within 200 meters of my home. I ALSO love that I can easily add other users via app, and that I can see what codes I gave them. The only thing that would make this better is a biometric (fingerprint or face).
