Security Testing
We evaluated 6 smart locks across physical security (pick resistance, bump resistance, drill resistance), digital security (encryption protocols, firmware update practices, vulnerability scanning), and reliability (10,000 lock/unlock cycles, extreme temperature testing, battery life).
Best Overall: Schlage Encode Plus ($279)
The Encode Plus combines ANSI Grade 1 physical security (the highest residential rating) with Home Key support for Apple users—tap your iPhone or Apple Watch to unlock. The built-in WiFi eliminates the need for a separate hub. Battery life averages 6 months with 10 uses per day. The fingerprint-resistant touchscreen keypad works reliably in rain and cold.
Best for Renters: August Wi-Fi Smart Lock ($229)
This retrofit lock installs on your existing deadbolt without replacing it—perfect for renters who can't modify hardware. Auto-unlock detects your phone approaching and unlocks automatically. Battery life is the weakest point at 3 months, and the August app occasionally shows delayed status updates.
Best Budget: Yale Assure Lock 2 ($179)
Available in keypad-only or touchscreen variants, the Assure Lock 2 offers reliable operation with Matter support for cross-platform compatibility. The slim profile fits most doors without modification. Battery life hits 12 months with 8 daily uses.
What to Avoid
Locks without physical key backup. We tested one popular model that bricked during a firmware update, leaving the homeowner locked out for 4 hours until a locksmith arrived. Always choose a smart lock with a traditional keyway as a failsafe.
