Setup
1. Battery Installation
Locate the battery compartment, usually at the back or inside the safe. Insert 3 AAA alkaline batteries, ensuring correct polarity. Close the compartment securely.
2. App Download and Pairing
Download the "Tuya Smart" or "Smart Life" app from your smartphone's app store (iOS or Android). Register an account if you don't have one. Follow the in-app instructions to add your K3F-tuya Smart Key Safe. This typically involves putting the device into pairing mode (refer to the device's specific instructions for this, often by pressing a button or holding a key on the keypad) and connecting via Bluetooth.
3. Fingerprint, Passcode, and IC Card Setup
Once paired with the app, you can set up various unlocking methods:
- Fingerprint: In the app, navigate to the fingerprint management section. Follow the prompts to register your fingerprints by placing your finger on the sensor multiple times from different angles.
- Passcode: Create a numeric passcode through the app. You can set temporary or permanent passcodes. The device supports anti-peeping passcodes, allowing you to enter random digits before or after your actual code for added security.
- IC Card: If your model supports IC cards, register them via the app by tapping the card on the designated sensing area.
