4. Operating Instructions
Your hornbill Smart Lock offers multiple convenient ways to lock and unlock your door.
4.1 Unlocking Methods

Place your registered fingerprint on the sensor. The lock will unlock within 1 second after identification. The lock features encryption and anti-hacker fingerprint reader chips for security.

- Passcode Unlocking:
Enter your registered passcode on the keypad. The lock supports up to 100 passcodes. If an incorrect password or fingerprint is entered more than 5 times, the lock will be temporarily disabled for 5 minutes.
- Anti-Peeping Passcode:
To prevent others from guessing your code, you can enter random digits before and after your actual passcode. For example, if your code is 369668, you can enter ****369668****. The lock will still recognize the correct sequence.

- App Control (Bluetooth/Wi-Fi):
Use the dedicated mobile application to unlock your door via Bluetooth when nearby, or remotely via Wi-Fi if a Tuya Gateway (ASIN: B0CQ4MK442, sold separately) is connected. The app allows for lock/unlock, user management, eKey sharing, and tracking operation records.
