Most HARFO smart locks are compatible with the TTLock App, which is available for download on the Apple App Store and Google Play Store. The app allows you to lock/unlock via Bluetooth, share e-keys, and manage users.
Remove the battery cover on the interior panel and press the "SET" button for approximately 5 seconds until you hear a beep or prompt. This will erase all user data and return the lock to its default state.
HARFO locks typically utilize 4 AA 1.5V Alkaline batteries. Rechargeable batteries are generally not recommended because their voltage (often 1.2V) may be insufficient for stable operation.
HARFO locks include a mechanical backup key for emergency access. Locate the keyhole on the exterior handle (often hidden under a cover cap or behind the handle) to manually unlock the door.
Depending on the specific model, HARFO locks can usually store between 100 to 120 unique fingerprints, allowing access for multiple family members or employees.
