Yale Assure Lock Wi-Fi Smart Module Upgrade Kit with hardware

I am widowed and have three dogs. I woke up several mornings and realized I failed to lock up after one or all three dogs got me up to go outside during the night. We have had a crime spree (as has the rest of the country) and I had to figure out how to avoid this happening again. I did not want unwanted guests. I also had to figure out how to enable entry for someone, a trusted individual, to gain access to my home in the event I needed assistance or they needed to do a welfare check. This lock does it all. It automatically locks a few seconds after the door is shut. It automatically unlocks when I have my iPhone with me, to allow my entrance and then locks after entry and door is shut. If I need to let someone in the house for some reason, and I am not close to allow them, I can remotely enable entry.
