What is the reason why the fingerprint lock panel screen is not bright? Jinan Laiwu Tea Town and Hezhuang Town are equipped with car keys to unlock cars.

　　First, the fingerprint lock panel screen is not bright reason analysis:

　　1. The fingerprint password lock has insufficient power, which may cause this situation. Solution: The battery needs to be replaced.

　　1: The fingerprint/password can’t be used normally. It is recommended to check whether the battery is exhausted.

　　2. The security door/fingerprint lock can’t be closed normally, so please don’t adjust it easily after installation by the installation master. For example, adding door stickers for door frames will lead to the original size no longer applicable.

　　3. The fingerprint lock/battery consumes a lot of power, so you can check the usage status of the battery, and check the battery power through the back operating system. If the power consumption is fast, you can initialize the fingerprint lock, and the battery will stand by for a longer time after initialization.

　　4: Fingerprint/password/key can’t open the door in case of emergency. You may buy inferior products or unqualified products (the lock body is scrapped or other parts). It is recommended to replace the products in time.

　　9: Waterproof protection. Fingerprint locks are electronic products. Although some manufacturers have made waterproof protection, please try to avoid contact with water or other liquids, or immerse them in water or other liquids. If the shell comes into contact with liquid or salt spray, please dry it with a soft and absorbent cloth.

　　10: Please use the high-quality 5# alkaline battery. Once the battery is found to be insufficient, please replace the battery in time. It is recommended to replace four or eight batteries at the same time to avoid the difference between the old and new batteries and the rapid loss, and also avoid the trouble of using an external battery to unlock. If you go out for a long time, you’d better remember to replace the new battery to prevent the battery from being damaged and the battery liquid from corroding the internal circuit.

　　11: If the fingerprint lock has been used for more than half a year, it is recommended to open the battery cover to check the battery to prevent the battery from electro-hydraulic corrosion of the fingerprint lock circuit board (especially in the rainy season, humid air will have hidden dangers to any household appliances, so please check and maintain it in time and use the fingerprint lock products correctly). If the battery is found to be oxidized, please replace it with a new battery with good quality.

　　12: Fingerprint lock with spare key, remember to put the key in the car or office and other places outside the home so as to be in urgent need.

　　13: When entering a fingerprint, it is recommended to write down the code, so as not to forget the code when deleting a fingerprint, and to avoid clearing the fingerprint lock.

　　14. The most basic ways to open a smart lock are fingerprint and password. Although most people will choose the most convenient fingerprint to open the door, it is recommended to set several sets of passwords at the same time, in case the fingerprint is broken, the password can be opened in an emergency, and if there is a visitor or an emergency, you can tell the password to open the door in an emergency and delete the password afterwards.

　　15: Do not disassemble without permission. Fingerprint locks are basically built with sophisticated electronic components, which may damage internal accessories or lead to other serious consequences when disassembled by non-professionals. If you suspect that there is a problem with the fingerprint lock, you’d better consult a professional or contact after-sales service to solve it.
