Who Is the August Fingerprint Door Lock For?
This lock is designed for homeowners who already use or plan to adopt the August smart lock ecosystem. It is ideal for those who want the convenience of fingerprint entry without needing to carry keys or use a smartphone. The lock is also suitable for families with multiple users, as it can store up to 100 fingerprints. It is less ideal for those seeking a lock with a built-in keypad or direct Wi-Fi connectivity without an additional bridge.
Performance and Build Quality
Based on published specifications and aggregated owner reviews from major retailers, the August Fingerprint Door Lock delivers reliable performance. The fingerprint sensor uses capacitive technology for quick and accurate recognition. Owners report that the sensor works well even with dry or slightly wet fingers, though it may struggle with very dirty or excessively moist digits. The lock motor is quiet and operates smoothly, with a low-profile design that fits most standard doors.
Build quality is consistent with August's reputation for durable construction. The lock body is made of zinc alloy, and the finishes are resistant to tarnishing. The lock is backed by a one-year limited warranty, which is standard for the category. Battery life is rated at 6-12 months with typical use, and the lock provides low-battery warnings via the app.
Alternatives to Consider
For those who prefer a built-in keypad, the Yale Assure Lock 2 with Wi-Fi offers a similar feature set with a more traditional interface. The Schlage Encode Plus provides Apple Home Key support and a fingerprint sensor built into the touchscreen. For a more budget-friendly option, the Wyze Lock Bolt offers fingerprint and keypad entry at a lower price point, though it lacks the refined app experience of August.
What to Check Before Buying
Before purchasing the August Fingerprint Door Lock, ensure your door is compatible. The lock requires a standard US deadbolt borehole (2-1/8 inch) and backset (2-3/8 or 2-3/4 inch). Check that your door thickness is between 1-3/8 and 1-3/4 inches. Also, verify that you have a reliable Bluetooth connection from your door to your smartphone, as the lock relies on Bluetooth for direct pairing. For remote access, you will need the August Connect Wi-Fi bridge, which is sold separately.
Mistakes to Avoid
One common mistake is assuming the lock includes Wi-Fi connectivity out of the box. The August Fingerprint Door Lock is a Bluetooth-only device; remote access requires the August Connect bridge. Another mistake is neglecting to register fingerprints for all household members immediately after installation. The lock can store up to 100 fingerprints, but each user must be added through the app. Finally, avoid installing the lock on a door that is not properly aligned, as this can cause the latch to bind and affect fingerprint recognition.
