So, why are smart locks equipped with mechanical keys?

In fact, this is a document issued by the Ministry of Public Security from a security point of view. Electronic smart locks sold in China must be equipped with mechanical keys. As an emergency unlocking under special circumstances, smart locks without mechanical keys cannot leave the factory.

Although the smart lock has brought us a lot of convenience, but in the event of some emergencies, after the electronic part of the smart lock is violated, problems may occur, resulting in the inability to use normally. At this time, the mechanical lock becomes The only way to open the door. This reminds us that the mechanical key must be kept properly.

Does the mechanical keyhole of a smart lock pose a risk to home security?

The mechanical keyhole of the smart lock is the same as the mechanical lock, and there is a risk of technical opening, so we must look for the C-level lock cylinder when purchasing. And many smart lock manufacturers have also taken a lot of measures to reduce the risk of technology opening.

For example, the highland barley smart lock has been designed with security issues in mind. In terms of appearance design, the mechanical keyhole is reserved in a hidden place, which is generally difficult to be found. Once someone steals the lock by violent unlocking, etc., the highland barley smart lock will immediately emit an alarm sound to scare off the criminals and send an alarm immediately. The situation is sent to the user's authorized mobile phone; in terms of internal structure, the highland barley smart lock uses a C-level lock cylinder, and the technical opening time can reach more than 270 minutes. Therefore, the security risk brought by the mechanical key is basically negligible.

Although the frequency of use of the mechanical key of the smart lock is very low, it should be kept well in order to avoid being unable to find it when using it.

Generally, a smart lock will be equipped with multiple mechanical keys. These keys are best stored separately. If they are all placed together, once the storage location is forgotten, these keys will be lost together. Therefore, it is recommended to place the mechanical key separately in the home, office, car, or in a fixed and hidden location in the parents' home, and keep it properly on the basis of ensuring safety.

Once the spare mechanical key is lost, for safety reasons, it is recommended to contact the manufacturer or maintenance master to replace the lock cylinder in time to avoid potential safety hazards and unnecessary losses.

The smart lock is equipped with a mechanical key, which is similar to a fire stair to a certain extent. Although it does not have an obvious role in normal times, it can play a key role in an emergency. Therefore, smart locks are equipped with mechanical keys to meet national standards on the one hand, and to better serve users for reasons of safety and convenience on the other hand.
