AI Verdict
This is a Wi-Fi connected smart lock that retrofits to your existing deadbolt, offering app and voice control for hands-free entry.
This lock is a situational fit because its retrofit design and broad smart home compatibility are strong, but frequent battery replacements and reported connectivity issues, especially with HomeKit, can be frustrating. The built-in Wi-Fi is a plus for avoiding a bridge, but it contributes to the battery drain.
If battery life is a top priority, look for smart locks that use standard AA batteries or have a longer stated battery life, or consider models with a wired power option.

What Buyers Say
The most surprising finding is the widespread complaint about battery life; despite built-in Wi-Fi being a selling point, it seems to contribute to CR123 batteries draining in 1-2 months for many, far short of expectations. Users also frequently mention struggles with HomeKit setup and maintaining a stable Wi-Fi connection. While the auto-unlock feature is praised when it works, its inconsistency can be frustrating. The compact size of this 4th generation model is a definite improvement, making it less obtrusive on the door.
“Honestly, this thing is a battery hog, I'm swapping out CR123s every month and a half, but when it actually connects to HomeKit and auto-unlocks, it's pretty sweet not fumbling for keys.”
Common Praise
- Installation is quick, often taking around 10 minutes, as it uses the existing deadbolt.
- The auto-lock and auto-unlock features are convenient when functioning correctly.
- The ability to grant virtual keys to family and guests is a highly valued feature.
- Its compatibility with Amazon Alexa, Google Assistant, and Apple HomeKit is appreciated by smart home users.
- The smaller physical size of the 4th generation lock is a noticeable improvement over previous models.
Common Complaints
- CR123 batteries often last only 1-2 months, requiring frequent and costly replacements.
- Connectivity issues, particularly with HomeKit and maintaining a stable Wi-Fi signal, are a recurring problem.
- The auto-unlock feature can be unreliable, sometimes unlocking after the user has already entered.
- The lack of an integrated physical keypad means an additional purchase for that functionality.
- Some users reported the device being blocked from activation outside the U.S..
Ownership Tips
- You'll want to buy CR123 batteries in bulk or invest in rechargeable ones, as you'll be replacing them often.
- Ensure your Wi-Fi signal is strong right at your door, as connectivity can be finicky.
- If you rely on HomeKit, be prepared for potential setup headaches and occasional drops in connection.
- The auto-unlock feature works best if you give it a moment to register your return before trying to open the door yourself.
- Check regional activation policies if you're outside the U.S., as some users have had their devices rendered useless.
Frequently Asked Questions
Does this lock replace my existing deadbolt?
No, the August Wi-Fi Smart Lock attaches to the inside of your door over your existing single-cylinder deadbolt, allowing you to keep your original keys.
What type of batteries does it use and how long do they last?
It uses CR123 batteries. While August suggests 3-6 months, many users report needing to replace them every 1-2 months.
Do I need a separate hub for Wi-Fi connectivity?
No, this 4th generation model has built-in Wi-Fi, so it connects directly to your home network without needing an additional bridge.
Is a keypad included with the lock?
No, a physical keypad is not included and must be purchased separately if you want that functionality.
Does it work with Apple HomeKit?
Yes, it is designed to work with Apple HomeKit, along with Amazon Alexa and Google Assistant, though some users report setup and connectivity challenges with HomeKit.
Buying Guide
When buying a smart lock, you need to decide if you want to replace your entire deadbolt or just upgrade the interior mechanism. This August lock is the latter, meaning your existing keys still work and the exterior of your door looks unchanged. Think about how important battery life is to you, as Wi-Fi enabled locks often consume more power. Also, consider your smart home ecosystem; ensure the lock explicitly supports your preferred voice assistant or platform.
Connectivity: Wi-Fi
Built-in Wi-Fi means the lock connects directly to your home network, allowing remote control and smart home integration without needing a separate bridge or hub. This simplifies setup but can increase battery consumption compared to Bluetooth-only locks.
Retrofits to your existing deadbolt
This is a big deal because it means you don't have to change the exterior look of your door or get new keys. The smart lock only replaces the thumbturn on the inside of your door, making installation easier and less disruptive.
Voice control (Amazon Alexa, Google Assistant, Apple HomeKit)
This allows you to lock or unlock your door using voice commands through compatible smart speakers or your phone. It's super convenient when your hands are full or you're already in bed and want to double-check the door.
Alternatives
If this lock doesn't fit, look for models that offer a physical keypad for code entry, or consider smart locks that replace the entire deadbolt for a completely new look and potentially different battery types.
