| Our verdict | This is a generic, low-cost solution best suited for interior doors or rentals where advanced automation is not required. It relies on Bluetooth and proprietary apps, posing significant longevity and security questions. | Kwikset provides a familiar physical locking mechanism with Wi-Fi connectivity, but the inconsistent user ratings suggest potential software instability. Ensure your Wi-Fi signal is robust at the door to avoid connectivity drops. |
