Welcome to the "Big Eye Observation" column. This column will bring together interesting and informative hot content in the industry, and everyone is welcome to watch it every week.
Because I often forget to bring the key, I also had the idea of buying a smart door lock. But because I saw that my friend Dai Boss, who earned millions of dollars a year, almost froze to death on the Second Ring Road because the smart door lock could not be opened in Beijing on the ninth cold day, I happily gave up this idea.
Boss Dai said that after work that night, he found that his door could not be opened, suspected that there was no electricity, and returned to the company to get the charging treasure, and the result was that the charging treasure could not be opened! After some tossing and turning, I could only report to the master to come.
It took a lot of effort, and finally entered the house. But after that night, the smart door lock still occasionally appeared that the panel was not bright, could not enter the password, could not enter the door of the case, the angry dai boss finally directly smashed the door, installed a new custom door, and the smart door lock was also replaced by a car specification. To have money is to be willful!
01 Smart door lock is cool for a while, and if there is a problem, it will be a garbage dump
Although there are many types of smart door locks on the market, there is no unified industry standard. According to industry insiders, many brands of smart door locks are produced by OEM, and brand owners cannot supervise the process of product OEM, and some companies do not even have the most basic testing equipment. Some smart door lock brands pay more attention to their marketing effects, and they have not done a good job in after-sales installation, and the weakness in after-sales will greatly affect the consumer experience.
Because the popularity of smart door locks is shorter, more lock unlockers are familiar with mechanical door locks. If there is a problem with the smart door lock, or you can't get into the house, many lock unlockers can't open it after they come, can't fix it, and finally can only violently remove the lock. The incidence of this situation is not low, a casual search for "smart door locks" on the Internet, you can see a lot of netizens with the same experience. It is really a good time to use, and if something goes wrong, you will directly throw it to the garbage dump.
02 Smart door lock is instantly cracked by a small black box, is the smart door lock safe?
Everyone buys smart door locks just to be more convenient and safer. But are smart door locks really safer? not necessarily.
At the 2019 International Door Industry Expo, someone holding a small black box instantly opened most of the smart door locks on display. The technical term of this small black box is "Tesla Circle", which generates a powerful electromagnetic field at the moment of opening, forms a strong magnetic pulse, breaks through the capacitive components of the smart lock, and makes the automatic lock run, thus cracking successfully.

Later, many big-name smart manufacturers added protection modules to the circuit of smart locks, so that the smart locks remain locked even if restarted, effectively preventing the locks from being unlocked by small black boxes. But these are only regular big brands, and the unknown smart locks on the market often cut corners, there is no guarantee in terms of security, and it is not surprising that they are cracked by small black boxes. Therefore, it is recommended that you choose a regular big brand when buying a smart lock, so that the security is more secure.
In short, the current smart door lock market is still in a stage of early development, there is no unified implementation standards, which requires us to be more cautious when purchasing smart door locks, giving priority to the products of regular manufacturers. Do readers and friends plan to buy smart door locks, or have they already encountered any problems with smart door locks?
