One, Reasons why the smart fingerprint lock cannot be opened
1、 Whether the power supply is sufficient or the batteries are counterfeit, as insufficient power can also cause the lock to intermittently open and close.
2. Prolonged use of fingerprint locks can cause excessive wear and tear on the main board, leading to battery leakage and inability to unlock the device. The solution is to replace the main board through the after-sales service department of this brand. Generally, replacements are free within the warranty period, and the standard warranty period for fingerprint locks is approximately 2 years.

For a typical consumer, it is straightforward to determine if the motor is damaged: if the motor can be activated and produce a "click" sound inside the lock, it indicates that the motor is not damaged. If no sound is produced, it indicates that the motor is damaged and needs to be replaced.
4、Damage to the main board can lead to excessive battery consumption, inability to unlock with the password and card (black screen), but the fingerprint sensor still functions.

6、Customers with low fingerprint recognition rates; typically elderly individuals, those with shallow fingerprints (flat, dry), or those whose fingerprints are frequently worn due to work. In these cases, fingerprint recognition may sometimes work and sometimes not, so it is recommended to use a card or password to unlock.
7、Security door sinking or detachment of hinges; if sinking, simply enlarge the hole in the door frame to resolve the issue; if hinges are detached, professional assistance is required.
