5. Operating Instructions
The IKOED smart door lock offers five convenient ways to unlock your door.

Figure 5.1: Multiple unlocking methods for the IKOED Smart Door Lock.
5.1. Fingerprint Unlock
The biometric fingerprint sensor allows for quick and secure access. Ensure the lock is "woken up" (e.g., by touching the keypad or sensor) before attempting to unlock with a fingerprint.
- Place your registered finger firmly on the fingerprint sensor.
- The lock will verify your fingerprint within 0.2 seconds.
- Once verified, the lock will unlock, and you can turn the handle to open the door.

5.2. Passcode Unlock
Enter your registered passcode on the keypad. The lock supports anti-peep functionality, allowing you to enter random digits before and after your actual passcode to prevent others from guessing it.
- Wake up the lock by touching the keypad.
- Enter your passcode (e.g., XXXX + Passcode + XXXX, where X are random digits).
- Press the '#' key to confirm.
- The lock will unlock if the passcode is correct.

5.3. IC Card Unlock
Use a registered IC card for quick tap-to-unlock access.
- Present the registered IC card to the card reader area on the lock.
- The lock will beep and unlock upon successful recognition.
5.4. Physical Key Unlock
In case of battery depletion or electronic malfunction, you can always use the provided physical keys for emergency access.
- Insert the physical key into the keyhole located on the exterior handle.
- Turn the key to unlock the door.
5.5. Auto-Lock Function
The lock can be configured to automatically lock after a set period (5 to 60 seconds) once the door is closed. This feature provides peace of mind, ensuring your door is always secured.
- This setting is managed via the Tuya app (see Section 6).
- Once enabled, the lock will engage automatically after the specified delay.

5.6. Anti-Lock Function (Privacy Mode)
The one-key anti-lock function, located on the backside of the interior handle, provides a privacy mode. When activated, only administrators can unlock the door from the outside, enhancing security and privacy within your space.
5.7. Silent Mode
The lock can operate in silent mode, muting all button beeps and voice prompts. This is ideal for maintaining quiet, especially during late hours. Silent mode is disabled by default after a factory reset.

5.8. Passage Mode
Passage mode allows the door to remain unlocked for free movement without restrictions. This is perfect for high-traffic areas or times when the door does not need to be secured.

8. Troubleshooting
If you encounter issues with your IKOED smart door lock, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Fingerprint not recognized. | Finger not placed correctly, sensor dirty, finger too cold/wet, unregistered fingerprint. | Ensure finger covers the sensor completely. Clean sensor. Warm/dry finger. Re-register fingerprint if needed, scanning from different angles. |
| Keypad unresponsive or not lighting up. | Batteries low or dead, lock not "woken up". | Touch the keypad to wake the lock. Replace batteries. Use emergency Type-C power if completely dead. |
| Lock does not engage/disengage. | Misalignment during installation, latch bolt obstruction, internal error. | Check door alignment and ensure nothing obstructs the latch. Re-check installation steps. Perform a factory reset if necessary (refer to app for instructions). |
