Maintenance
Battery Management:
The Lockin Veno Smart Lock is powered by a rechargeable Lithium Polymer battery, offering up to 7 months of life. When the battery level drops below 20%, you will receive automatic notifications via the app. To recharge, remove the battery pack and connect it to a USB-C charger. In an emergency, the exterior unit has a USB-C port for temporary power from a power bank.
An optional solar charging panel (sold separately) can be used for continuous charging without removing the battery.
Cleaning and Care:
To maintain the appearance and functionality of your smart lock, wipe the exterior surfaces with a soft, damp cloth. Avoid using abrasive cleaners or solvents, as these can damage the finish and electronic components. Ensure the palm vein and fingerprint sensors are kept clean for optimal performance.
Troubleshooting
If you encounter any issues with your Lockin Veno Smart Lock, please refer to the following common troubleshooting steps:
- Lock Not Responding: Check the battery level. If low, recharge the battery. If the battery is completely drained, use a power bank via the external USB-C port or the mechanical key.
- Palm Vein/Fingerprint Recognition Failure: Ensure your hand/finger is clean and dry. Try re-registering your biometric data in the app. Ensure proper placement over the sensor.
- App Connectivity Issues: Verify your Wi-Fi connection. Ensure the lock is within range of your Wi-Fi router. Restart the app and, if necessary, the lock.
- Passcode Not Working: Double-check the entered passcode. Ensure the lock is not in a temporary lockout mode due to multiple incorrect attempts.
