6.1 Unlocking Methods
The Smart Key Box supports multiple ways to unlock:
- Fingerprint Unlock: Place a registered finger on the fingerprint sensor. The sensor offers 360-degree recognition with a quick 0.3-second response time and can store up to 100 user fingerprints.
- APP Unlock: Open the TTLock or Tuya app on your smartphone. If within Bluetooth range, you can unlock directly. For remote unlocking over Wi-Fi, a compatible gateway (sold separately) is required.
- Password Unlock: Enter your 6-16 digit password on the keypad. The anti-peep function allows you to enter random digits before or after your actual password to prevent others from guessing it.
- IC Card Unlock: Tap a registered IC card on the designated area of the key box.
6.2 App Features (TTLock Example)
The mobile application provides comprehensive control over your key box:
- Touch to Unlock: Unlock directly via Bluetooth from the app.
- Send Password: Generate and send temporary or permanent passwords to users.
- Send eKey: Grant access to others via eKeys, which can be time-limited or permanent.
- Card Management: Add, delete, or manage IC cards.
- System Settings: Configure various settings for the key box.
- Fingerprint Management: Add, delete, or manage registered fingerprints.
- Password Management: View and modify existing passwords.
- View Unlock Record: Access a log of all unlock events, including method and user.
- Authorized Admin: Manage administrative access for other users.
6.3 Remote Access (with Gateway)
To enable remote unlocking and management over Wi-Fi, you will need a compatible gateway. The key box supports TTLock G2 Gateway or BLEMESH (SIG) / TUYA Gateway.
Once connected to a gateway, you can remotely generate one-time passcodes, check unlock records, and manage users from anywhere with an internet connection.
6.4 Emergency Power Supply
In case the AAA batteries run out, the key box can be temporarily powered via a USB cable connected to a power bank. This allows you to unlock the box and replace the batteries.
7. Maintenance
- Battery Replacement: Replace the 4 AAA alkaline batteries when the app indicates low battery or when the key box shows signs of low power (e.g., slow response, dim lights).
- Cleaning: Wipe the key box surface with a soft, damp cloth. Avoid using abrasive cleaners or solvents.
- Inspection: Periodically check for any physical damage or wear and tear, especially if installed outdoors.
8. Troubleshooting
- Key box not responding: Check battery levels. If batteries are depleted, use the USB backup power supply to open the box and replace them.
- App connection issues: Ensure Bluetooth is enabled on your phone and you are within range. If using a gateway for remote access, ensure the gateway is powered on and connected to the internet.
- Fingerprint not recognized: Ensure your finger is clean and dry. Try re-registering your fingerprint if issues persist.
- Password not working: Double-check the entered password. Remember the anti-peep function allows extra digits, but the core password must be correct.
- Remote functions not working: Verify that a compatible gateway is properly set up and connected to both the key box and your home Wi-Fi network.
9. User Tips
- Battery Life: While the app should report battery levels, consider using high-quality alkaline batteries for optimal performance and longer life.
- App Choice: The key box supports both TTLock and Tuya apps. Choose the app that best fits your existing smart home ecosystem or personal preference.
- Remote Access: For full remote functionality, including changing combinations via Wi-Fi, ensure you purchase and set up a compatible gateway.
