Frequently Asked Questions
Q: Does the smart fingerprint key lock box require WiFi to work?
A: No, WiFi is optional. The box works via Bluetooth (BLE 4.0) for local app control within 10 meters, fingerprint, PIN code, and IC card — all without WiFi. To enable remote WiFi access from anywhere, you will need the G2 Gateway Bridge (for the TTLock app) or the M1 Gateway Bridge (for the Tuya / Smart Life app), sold separately.
Q: What is the difference between the K3F and K5F models?
A: Both models share the same smart unlock features and zinc alloy construction. The primary differences are in weather resistance and weight: the K5F offers a higher IP65 waterproof rating and weighs 0.9 kg, while the K3F is rated IP54 and weighs 1.0 kg. Choose K5F for more demanding outdoor/wet environments.
Q: Can I share access with multiple people?
A: Yes. The lock box supports up to 150 unique PIN code groups and allows you to add multiple fingerprints and IC cards. Through the Tuya or TTLock app, you can grant temporary or permanent digital access to family members, guests, or service providers and revoke it at any time remotely.
Q: What happens if the batteries die?
A: The lockbox includes an emergency external power supply port. You can connect a power bank or compatible power source to the port to temporarily power the box and unlock it, then replace the AAA batteries at your convenience.
