Fingerprint Keypad Door Lock Maintenance

1. Clean the Door Lock Surface Regularly

We recommend using a microfiber cloth dampened with a small amount of water or neutral detergent monthly to gently wipe the surface of the Fingerprint Keypad Door Lock to remove dust, stains, and fingerprints. Avoid using harsh cleaning tools or strong acidic or alkaline cleaners to prevent scratching or corroding the door lock surface. Pay special attention to the fingerprint sensor and keypad area. Gently wipe with a cotton swab dampened with a moderate amount of alcohol to remove any residual grease and dirt.

2. Replace Batteries Promptly

Pay attention to the battery indicator on the door lock. When the door lock emits a low-battery warning tone, replace the batteries within a week. Use high-quality alkaline batteries and avoid using inferior batteries to prevent leakage and damage to the door lock's internal circuitry. When replacing the batteries, install them correctly according to the instructions on the back cover of the door lock, ensuring the positive and negative terminals are correctly oriented. It is recommended to remove the batteries when the door lock is not in use for an extended period to prevent self-discharge and depletion.

3. Regularly Check the Fingerprint Sensor

Perform a performance check on the fingerprint sensor quarterly. You can use a fingerprint sensor test tool or contact the door lock manufacturer for technical support. Test the fingerprint recognition accuracy and response speed. If the recognition rate is less than 95% or the response time exceeds 2 seconds, clean the sensor surface or contact a professional for repair.

4. Regularly inspect the lock tongue and lock body

Perform a comprehensive inspection of the lock tongue and lock body every six months. Check whether the lock tongue extends and retracts smoothly and whether the lock body fits tightly against the door frame. If there is any sticking or excessive play, lubricate the moving parts of the lock tongue and lock body with lubricant. Inspect the internal mechanical structure of the lock body for signs of looseness or damage. If any problems are found, contact a professional repair technician for replacement or repair.

5. Prevent erosion from humid environments

If the door lock is installed in a high-humidity environment (such as near a bathroom, kitchen, or basement), moisture-proof measures must be taken. Place moisture-proof gaskets, such as silicone gaskets or waterproof sealing strips, at the contact area between the lock and the door frame to prevent moisture from entering the lock body. Regularly inspect the moisture-proof gaskets for integrity and replace them if damaged.

6. Regular Functional Testing

We recommend a comprehensive test of all Fingerprint Keypad Door Lock functions quarterly. This test includes fingerprint recognition, password entry, ID card reading, mechanical key unlocking, and anti-theft alarm. If any issues are found during testing, please note them immediately and contact a professional repair technician for resolution.

Fingerprint Keypad Door Lock FAQ

1. Is the installation process complicated?

The Fingerprint Keypad Door Lock installation process is straightforward, and a typical installer can complete it in 45 minutes. The door lock comes with detailed installation drawings and instructions, with clear, easy-to-follow steps. Experienced installers will find the process smooth and efficient, while users with more DIY skills can also complete the installation smoothly by following the instructions.

2. What should I do if fingerprint recognition isn't accurate after installation?

If fingerprint recognition isn't accurate after installation, first check the fingerprint registration quality. The door lock's fingerprint sensor has an accuracy of ±0.001mm. When registering, ensure your finger is clean, dry, and placed steadily, covering approximately two-thirds of the sensor surface. Registering the same fingerprint multiple times from different angles can improve recognition accuracy. If the registration is correct, the sensor surface may be stained or scratched. Use a soft cotton swab dipped in a little alcohol to gently wipe the sensor to remove oil and impurities.

3. How can I quickly resolve a door lock malfunction?

The door lock has a self-diagnostic function. When a malfunction occurs, the screen will display an error code, such as E01 or E02, allowing the user to initially determine the fault type. A common low battery problem is that the door lock will emit a warning tone when the battery level drops below 15%. At this time, the batteries should be replaced promptly. Using high-quality alkaline batteries can prevent malfunctions caused by battery quality issues. If you are unsure of the cause of the problem, please contact us.
