4. Setup and Installation
The Viladepot Smart Lock D6 is designed for easy installation, typically taking around 10 minutes. No extra drilling is required for standard door preparations.
4.1 Door Compatibility
The lock is compatible with door thicknesses between 35mm and 50mm (1-3/8" to 2"). It supports a 2-3/8" (60mm) or 2-3/4" (70mm) backset and a 2-1/8" (54mm) door hole. The handle direction is reversible for both left-handed and right-handed doors.

4.2 Installation Steps
Before starting, ensure the front and rear handles are covered with protective film. This film should only be removed after the installation is complete.
- Install the Lock Body: Adjust the backset of the lock latch as needed, then fix it to the door with 2 self-tapping screws. If the striking plate does not match your door grooves, you may change the door hole or use the old latch directly.
- Install the Front Panel Copper Column: Pull out the cable and straighten it. Thread the hollow square bar through the cable to the bottom of the front handle. Attach the 2 screw bolts to the front cover. Be careful not to damage the cable.
- Install the Square Bar: Insert the square bar into the mechanism.
- Remove the Rear Panel Baffle: Carefully remove the baffle from the rear panel.
- Connect the Data Cable: Connect the cable to the interface of the rear PCB according to the diagram, ensuring the connections align with the red mark to prevent crooked pins.
- Install the Spring and Rear Panel: Attach the spring to the rear handle to prevent the hollow square bar and drive shaft from disengaging. Inset the front handle into the door hole, ensuring the screw bolts and hollow square bar pass through the latch bolt. If the door is more than 1.5 inches (38mm) thick, a spring needs to be placed on the rear handle.
- Secure and Power On: Screw on the screws, install 4 x AAA alkaline batteries (ensure they are high-quality to avoid performance issues), and then close the battery baffle.
Important Safety Note: Do not use the mechanical key to unlock the device until the installation is fully complete and the drive shaft is homed. Using the key prematurely can damage the drive shaft. The mechanical key should only be used as a last resort for unlocking.

6. Maintenance
6.1 Battery Management
The lock is powered by 4 x AAA alkaline batteries. We recommend replacing all batteries every 6 months to ensure consistent performance.

Low Battery Alert: The lock will provide low battery alerts when power is below 30%. It is highly recommended to replace the batteries promptly when this alert occurs.
Emergency Power: If the batteries completely die, you can use the USB-C emergency power port on the exterior handle to provide temporary power with a power bank. This allows you to unlock the door and replace the batteries.

DO NOT attempt to recharge the AAA batteries through the emergency power port; it is for temporary power only.
6.2 Cleaning
Regularly clean the fingerprint scanner to remove any built-up dust or oil, which can reduce its sensitivity and lead to failed entries.
7. Troubleshooting
7.1 Fingerprint Scanner Not Responding Well
If the fingerprint scanner is not consistently recognizing your fingerprint:
- Re-register Fingerprint: Try deleting and re-registering your fingerprint in the app. You can store the same fingerprint multiple times to improve accuracy.
- Clean Sensor: Ensure the fingerprint sensor is clean and free from dust, dirt, or oil.
7.2 Door Not Unlocking
If the door lock is not responding or unlocking:
- Check Battery: Verify that the batteries are not depleted. Use the emergency USB-C port if needed, and replace batteries immediately.
- Handle Level: Ensure the handle is level. If it hangs down, it can affect unlocking. Lift the handle to unlock and adjust it to be level.
- Cable Connection: Check if the internal data cable is properly connected and that the pins are not deformed.
- Mechanical Key: Use the mechanical key as an emergency backup.
7.3 App Connectivity Issues
If the app cannot find or connect to the device:
- Ensure Bluetooth and Location services are enabled on your smartphone.
