Table of Contents
SMARTSAFEGEAR SCORE
The smart lock market has three clear leaders: August Wi-Fi Smart Lock, Schlage Encode Plus, and Yale Assure Lock 2. Each takes a different approach to the same problem, and the best choice depends on your priorities around design, security rating, smart home ecosystem, and budget. We installed all three and lived with them for 45 days.
Key Features We Tested
Design & Installation: August Wins: The August lock fits over your existing deadbolt, meaning you keep your exterior hardware and existing keys. Installation takes 10 minutes with no drilling. Schlage and Yale replace your entire deadbolt, which is a bigger commitment but delivers a more integrated look. The August retrofit approach is ideal for renters.
Physical Security: Schlage Wins: The Schlage Encode Plus has an ANSI/BHMA Grade 1 rating, the highest available for residential locks. Yale Assure Lock 2 is Grade 2. August is not independently graded because it uses your existing deadbolt. If physical security is paramount, Schlage is the clear choice.
Apple HomeKit: Schlage Wins (Home Key): Schlage is the only lock with Apple Home Key, letting you tap your iPhone or Apple Watch to unlock. August supports HomeKit (with Bluetooth) and Yale supports HomeKit (with Wi-Fi module). But only Schlage offers the tap-to-unlock Home Key experience.
Google/Alexa Integration: Yale Wins: Yale Assure Lock 2 has the most flexible module system, supporting Wi-Fi, Bluetooth, Z-Wave, or Zigbee. This makes it compatible with virtually every smart home platform. August works with Alexa, Google, and HomeKit. Schlage works with all three.
Value: August Wins: At $190, the August Wi-Fi Smart Lock undercuts Schlage ($300) and Yale ($220). Since it preserves your existing deadbolt and keys, you save additional hardware cost. For most users who want smart lock convenience at the best price, August delivers.

Frequently Asked Questions
Which smart lock is the most secure?
The Schlage Encode Plus with its Grade 1 ANSI/BHMA rating provides the highest physical security. However, all three locks are secure for residential use, and the smart features (auto-lock, alerts) add security beyond the deadbolt itself.
Can a locksmith open a smart lock?
Yes. All three locks can be opened by a locksmith. August uses your existing key, Schlage includes a key override, and Yale includes a key override. Smart features do not prevent locksmith access.
What happens if the battery dies?
All three locks provide low-battery warnings weeks in advance. If the battery dies, August and Yale can be jump-started with a 9V battery on the exterior. Schlage has a USB-C emergency power port.
Are smart locks safe from hacking?
Modern smart locks use AES-128 or AES-256 encryption. Real-world hacking of these locks is extremely rare. Physical lock picking or forced entry remains far more likely than electronic hacking.
Which smart lock has the best battery life?
August typically lasts 3-6 months. Yale lasts 6-9 months. Schlage lasts 6-12 months. Actual life depends on usage frequency and Wi-Fi activity.
