I had this lock installed in January 2024 and had no idea exactly how great of an investment it would turn out to be.  Shortly after my doors and lock were installed, I suffered a medical emergency that has severely limited my mobility.    In addition, stress aggravates my condition.  This lock has reduced my stress by enabling my kids to unlock the door with their iPhones and watches.  I am able to lock the door from anywhere in the house -or just check to make sure it’s locked.  I have friends and family checking on me and I can let them in from anywhere.  This has truly been a game changer for me.
