Yale August Silver
Score: 85/100
Philips Smart Lock
Score: 72/100Rankings

The Yale August Wi-Fi Smart Lock is a premium retrofit solution that offers built-in Wi-Fi and fingerprint biometrics for keyless entry. Its main trade-off is the high cost associated with purchasing the Keypad Touch separately and limited compatibility with single-cylinder deadbolts. It is best suited for renters or homeowners seeking a non-intrusive upgrade with advanced smart home integration.

The Philips 4000 Series Wi-Fi Smart Keypad Deadbolt is a hub-free smart lock featuring built-in Wi-Fi, fingerprint recognition, and PIN code access for remote home security. It offers ANSI/BHMA Grade 3 certification, adjustable auto-locking, and integration with major voice assistants like Alexa and Google Assistant. While it lacks emergency power options and has a lower battery life than some competitors, it is ideal for users seeking affordable, hub-free Wi-Fi smart locks with keypad and fingerprint features for front doors.
