Frequently Asked Questions
Q: Can the YRHAND F6 smart lock be used on a courtyard grille or iron gate door?
A: Yes — the F6 is specifically designed for courtyard grille doors, narrow-frame aluminum doors, and decorative iron gates. Its double-sided panel means both the exterior and interior sides have fingerprint, keypad, and card access, preventing anyone from reaching through the grille to operate the lock from the inside.
Q: Does the F6 smart lock work without a WiFi gateway?
A: Yes. Without a gateway, the F6 operates via Bluetooth using the TTLock app (requires proximity), as well as fingerprint, password, IC card, and mechanical key. To enable full remote control, real-time notifications, and cloud features from anywhere in the world, the optional G2 WiFi Gateway is required.
Q: What happens if the batteries run out completely?
A: The F6 includes a USB Type-C emergency power port on the exterior panel. Simply connect a power bank or USB charger to temporarily power the lock and enter your code or use your fingerprint to unlock. The low battery alarm also alerts you well in advance to avoid being locked out.
Q: Is the YRHAND F6 compatible with Alexa and Google Assistant?
A: Yes — when paired with the optional G2 WiFi Gateway, the F6 integrates with Amazon Alexa and Google Assistant, allowing voice-command control and smart home automation routines.
