Fingerprint recognition failure may be caused by the following reasons. Please troubleshoot according to the following steps:  
1. Check if the smart lock is powered on: Fingerprint recognition will not work when the device is powered off. Please ensure the lock is properly powered.  
2. Ensure your finger is clean: Dirt, water, or oil on your finger may affect recognition. Please wipe it clean and keep it dry before trying again.
3. Check if the fingerprint sensor is clean: Dust or water stains on the sensor surface may interfere with recognition. Please clean the sensor with a dry cloth.
4. Check the quality of the fingerprint and the enrollment method:
● If the finger is too dry, too wet, peeling, or worn, it may affect recognition.
● Keep your finger in a natural position during enrollment, avoid applying excessive force, and capture multiple angles whenever possible.
● Elderly individuals may have more severely worn fingerprints; it is recommended to enroll multiple fingerprints from different angles to improve unlock success rates.
● Children's fingerprints are shallow and may change as they grow. If recognition rates decrease, it is recommended to re-enroll the fingerprints.  
5. Pay attention to the usage environment: Extreme temperatures or humidity may affect recognition performance.  
6. Try other unlocking methods: If recognition still fails, you can use a password, key, or mobile app to unlock.  
If recognition still fails after multiple attempts, it is recommended to re-enroll the fingerprints or contact the after-sales team for further assistance.

If the password unlock fails, we recommend checking the following common causes:  

1. Ensure the smart lock is powered on: The device will not function properly if it is powered off. Please ensure the battery is charged.  

2. Ensure the screen is activated: Before entering the password, ensure the touchscreen is awake and the numeric keys are illuminated.  

3. Verify the password is entered correctly: Avoid accidental touches, rapid consecutive presses, or incorrect digit order.

4. Check the alignment of the lock bolt with the door frame: If the lock bolt is deformed and not fully aligned with the door frame, it may become stuck, causing the unlocking to fail.

5. Try other unlocking methods: If the password fails multiple times, you can use fingerprint recognition, a key, or the mobile app to unlock the door.

The lock tongue may be stuck due to misalignment during installation or use. We recommend troubleshooting as follows:  
1. Check the alignment of the lock tongue with the door frame: If the lock tongue is deformed and not fully aligned with the door frame, it may cause the lock tongue to get stuck.  
2. Try recalibrating: You can recalibrate the device under Device Page - Settings - General - Device Calibration.
3. Confirm whether the door is closed too tightly or deformed: sagging, deformation, or loose hinges on the door may affect the lock tongue's movement.
If the lock tongue remains stuck after calibration, please contact the after-sales team for further assistance.

If the DESLOC App experiences lag, unresponsiveness, or crashes, try the following steps to resolve the issue:  

1. Close and reopen the App: Completely close the background app and restart the App to see if it returns to normal.  

2. Certain specific features can only be used when the device is nearby and do not support remote use, such as resetting the device or changing Wi-Fi.  

3. Check the network connection: Ensure that your phone's network connection, Wi-Fi, or mobile data is functioning properly.

4. Update the app version: Go to the app store to check for the latest version and update promptly to fix known issues.

5. Restart the phone device: Temporary system abnormalities on the phone may cause the app to lag. It is recommended to restart the phone and try again.

If the issue persists, please contact official customer service to report the specific situation (such as device model, system version, issue screenshots, etc.) so that we can assist in resolving it as soon as possible.

If the device fails during calibration, please follow these steps to check and troubleshoot the issue:  

1. Verify proper installation: Ensure the door lock is installed correctly according to the manual, including proper alignment of the lock body, latch, and door frame. Any misalignment may affect calibration.  
2. Ensure the user is within range: During calibration, ensure the user is within the device's Bluetooth range.
3. Verify that the phone's Bluetooth is enabled: Calibration relies on Bluetooth communication. Please ensure that Bluetooth is enabled in the phone settings and has successfully connected to the door lock.  
4. Try restarting the device and app: Restart the app or power cycle the door lock, then attempt the calibration process again.  
If calibration still cannot be completed, we recommend contacting official after-sales customer service for further technical support.

If the door lock status displayed in the app does not match the actual status, please follow these steps to troubleshoot:
1. Try manually refreshing: Pull down to refresh the app and check if the status has been updated correctly.
2. Check the network connection: Poor network signal may cause status delays or errors. Please ensure the device has a stable network connection.
3. Avoid frequent operations on the door lock within a short period: Frequent opening and closing of the door within a short period may cause conflicts in status information. It is recommended to wait a few seconds before performing the operation again.
If the status remains abnormal after attempting the above methods, please contact after-sales customer service for further assistance.
