What's New

Affected by the cold wave, many areas in the country have started a large-scale cooling mode. When the temperature drops to a certain level, it will have many impacts on the use of many electronic products. Taking smart locks as an example, the probability of fingerprint recognition failure in winter will be higher than usual; changes in temperature can lead to different situations, affecting product use and even causing door locks to malfunction. According to feedback from dealers, there will be more after-sales service requirements for smart locks in winter.

Check the battery level frequently, ask for timely after-sales service in case of battery abnormalities

At present, 3D facial recognition and video locks are very popular, and most of these products use lithium batteries to maintain battery life. However, in severe cold conditions, although the lithium battery compartment is located indoors, it can also be affected by low temperatures. Therefore, when using smart locks in winter, it is necessary to check the battery level of the door lock frequently. If you find that the battery level is low, remember to replace it in a timely manner. In addition, if you find any damage or leakage in the battery, be sure to contact the manufacturer's after-sales service in a timely manner.

If the door lock uses a dry battery, it is recommended to use alkaline dry batteries as much as possible. Firstly, the capacity of alkaline batteries is much higher than that of ordinary dry batteries. Secondly, the chemicals in dry batteries are fixed and the discharge amount is relatively constant. Compared with lithium batteries, they are less affected by low temperatures. In winter, you can keep a few extra batteries at home to prevent unexpected situations.

Remove static electricity to prevent recognition failure

In dry winter, it is easy to generate static electricity. In fact, most smart door lock products on the market now have anti-static protection, but some low-quality smart locks may not be guaranteed. Generally speaking, low-quality smart locks are more susceptible to static electricity, which can affect recognition. If people are prone to static electricity in winter, they can use metal to remove the static electricity before use.

Pay attention to finger temperature and humidity to improve fingerprint recognition accuracy

After entering winter, the temperature will be very low, and people's skin will be very dry. The surface of the skin that is too dry and the peeling of fingers caused by dryness can also lead to the inability to recognize fingerprints and unlock. At this point, the hand can be kept warm by exhaling on the fingers, allowing for accurate recognition of living organisms. 

Secondly, in winter, people usually apply hand cream on their hands. If the hand cream is too thick, it can also affect the accuracy and speed of fingerprint recognition. Similarly, if there is water on the hand, it can also affect fingerprint recognition. At this point, you can wipe off the hand cream by wiping off the fingers that need to be verified.

Thirdly, if the fingerprint recognition is unsuccessful multiple times, you can move your finger and try from different angles. If the above methods are not working, it is recommended to choose a password as the main unlocking method.

Commonly used soft cloth to wipe the fingerprint collector

If there are no issues with the humidity, temperature, etc. of the fingers, but it still indicates that fingerprint collection has failed, it may be a problem with the fingerprint collector, such as dirt on the fingerprint collector, which affects the accuracy of fingerprint collection. In this case, the user needs to clean the fingerprint collector with a dry soft cloth, and cannot use hard objects such as iron shavings to wipe, otherwise it will scratch the fingerprint head and affect its use.

Often open windows for ventilation and prevention of condensate short circuit

The vast majority of smart locks have battery compartments designed at the back panel. When the indoor temperature and humidity are relatively high and the external temperature is relatively low, if cold air enters the room, the rear panel is prone to condensation of water droplets. When water droplets enter the battery compartment, it is easy to cause a short circuit in the battery, which affects the normal use of the smart lock.So, when encountering a significant drop in temperature, users should remember to close the doors and windows tightly when going out, and also do a good job of sealing the doors and windows to reduce cold air entering the room. Finally, it is necessary to open windows appropriately for ventilation and eliminate indoor moisture.Any electronic product has this major taboo, such as a mobile phone. If it is not waterproof, it will generally be scrapped if it gets wet, and fingerprint locks are no exception. Currently, most smart door locks do not have waterproof functions, and the electronic components or circuit boards inside the lock are likely to malfunction once they get wet. So, users should also avoid trying smart locks outdoors to avoid unnecessary trouble. When returning home on rainy and snowy days, be careful not to let the rainwater on the rain gear fall on the smart lock merchant. If the shell comes into contact with liquid or salt spray, please dry it with a soft, absorbent cloth.

Other product malfunctions

During the use of electronic products, it is inevitable to encounter some malfunctions, especially in harsh environments such as low temperatures, where the probability of malfunctions occurring is relatively high. If the door cannot be opened due to product issues, it is recommended to immediately call the brand's after-sales service for timely on-site repair. At the same time, regular maintenance can also be carried out, which will reduce the probability of failure at critical times and extend the service life.
