There is no need to worry about this issue at all. The current fingerprint lock operation is like a fool's machine operation. At present, all merchants' smart locks are basically provided with full voice prompts, which can be operated according to the prompts. Professional installation personnel will teach you how to use the fingerprint lock as soon as it is installed, and provide detailed instructions. Elderly people and children can also use it easily. Nowadays, with the improvement of people's living standards and the upgrading of public consumption, intelligent products are also increasingly favored. Intelligent products not only provide people with a unique user experience, but also enhance their happiness index in family life. The door lock, as a barrier to family safety, plays the role of "one person can handle it, ten thousand people cannot open it". 
Recently, smart locks have become a hot topic in the lock market and have become a popular model on the internet. However, smart locks have not escaped the law of "popular right and wrong", such as excessive praise for consumption, overpriced locks, poor after-sales service, and other issues. As a result, the development of smart locks has not been as high as we expected, and data fluctuations have been leveling off, even tending to decline. In fact, in summary, there is a lack of communication. Sometimes when consumers encounter problems and do not receive timely relief or the desired solution, they will make up their own minds.
So as a lock company that craves continuous upward development, how should we solve this annoying after-sales problem? What can we do to not only eliminate consumers' worries, but also timely feedback customers' opinions and requirements on the product to the enterprise, prompting the enterprise to continuously improve product quality and better meet customer needs?
