Life with preschoolers has enough challenges. getting locked out on the porch while checking for mail shouldn't be one of them. We replaced our lock with a Schlage Sense keyless deadbolt and can now control our lock with a code or using our phones.
Schlage Sense Smart Deadbolt with Camelot Trim in Satin Nickel (BE479 CAM 619)
Designed with built-in Apple HomeKit technology the Schlage Sense Door Deadlock allows you to unlock and lock your front door from your iPhone by an app or simply asking Siri. It also includes a touchpad and manual traditional key as a backup.
