AI Verdict

This retrofit smart lock with built-in Wi-Fi and included keypad is for managing guest access and smart home integration, but expect frequent battery changes.

Situational Fit

This lock is a strong contender for specific use cases like vacation rentals or for renters due to its retrofit design and comprehensive guest access features. However, the frequently reported short battery life with Wi-Fi enabled is a significant trade-off that impacts its general appeal.

If battery life is a top priority, look for smart locks that use Z-Wave or Zigbee connectivity, often paired with a separate hub, as these protocols consume less power.

What Buyers Say

The most surprising finding is how consistently users complain about battery life, often needing to replace the four AA batteries every 1-2 months when Wi-Fi is active. Despite this, many appreciate the convenience of auto-lock/unlock and the ability to easily manage guest access with virtual keys and the included keypad. However, reports of poor customer service and occasional connectivity glitches, particularly with HomeKit setup, are recurring themes.

“Ugh, the battery life on this thing is a joke, I'm constantly buying new AAs. But honestly, being able to send codes to my Airbnb guests and not worry about keys? That's worth the hassle, mostly.”

Common Praise

  • Installation is quick and easy, often taking around 10 minutes over an existing deadbolt.
  • The auto-lock and auto-unlock features work reliably for many, adding significant convenience.
  • Sharing virtual keys for guests or family through the app is a highly valued feature.
  • The included Smart Keypad provides a simple code-based entry option without needing a phone.
  • Wide compatibility with smart home ecosystems like Alexa, Google Assistant, and Apple HomeKit is frequently mentioned.

Common Complaints

  • Batteries drain very quickly, with some users reporting replacement every 45-60 days when Wi-Fi is used.
  • Customer service is often described as unresponsive or unhelpful by multiple users.
  • Connectivity can be inconsistent, with reports of Wi-Fi drops or issues with auto-unlock on Android and HomeKit.
  • Some users have experienced the lock failing or 'bricking' after a battery change.
  • The product cannot be activated or used outside the U.S., leaving international buyers with a useless device.

Ownership Tips

  • Expect to purchase a lot of AA batteries, as Wi-Fi usage significantly shortens their lifespan to potentially less than two months.
  • Auto-unlock functionality can be less consistent if your phone's location services or Bluetooth are not perfectly optimized.
  • You might encounter frequent low battery alerts in the app, requiring proactive replacement to avoid being locked out.
  • The physical size is noticeably smaller than older August Smart Lock models, making it less obtrusive on the door's interior.
  • While it works with HomeKit, initial setup can sometimes be finicky and require multiple attempts or workarounds.

Frequently Asked Questions

Does the August Wi-Fi Smart Lock replace my existing deadbolt?

No, it's a retrofit smart lock that installs on the inside of your door over your existing single-cylinder deadbolt, allowing you to keep your original keys and exterior hardware.

Do I need a separate hub or bridge for this smart lock?

No, this model has built-in Wi-Fi, so it connects directly to your home network without requiring an additional bridge or hub.

How long do the batteries typically last in this lock?

User experiences vary, but with Wi-Fi enabled, many users report needing to replace the four AA batteries every 45-60 days.

Can I still use my physical keys with this smart lock installed?

Yes, since it only replaces the interior thumbturn of your deadbolt, you can continue to use your original physical keys from the outside.

What smart home systems is this lock compatible with?

It integrates with a wide range of smart home ecosystems, including Amazon Alexa, Google Assistant, Apple HomeKit, and Samsung SmartThings.

Buying Guide

When considering this smart lock, you need to understand it's a retrofit solution, meaning it attaches to your existing deadbolt's interior. This is fantastic if you're a renter or want to keep your current keys and exterior look. The built-in Wi-Fi means remote access without extra gadgets, which is convenient. However, that Wi-Fi convenience comes at a cost: battery life. Be prepared for regular battery changes, potentially every month or two, especially with heavy use.

Alternatives

If frequent battery changes are a deal-breaker, look for smart locks that use lower-power wireless protocols like Z-Wave or Zigbee (though these often require a separate hub). If you're open to replacing your entire deadbolt for a more integrated look and potentially enhanced security, search for full smart deadbolt replacements.
