It’s rainy and miserable in the south. It rains every day in spring in the south. The sun seems to have disappeared... It’s rare to see the sun a few times throughout the spring. Spring has returned to the south again, and every day when I go home, the floors, windows and walls are all wet. At this time, if the mechanical lock is infected by wet weather... (The poor quality one will disintegrate directly from the inside) (In the middle of the night, I persuaded the locksmith to come to the door with good words) (My life experience of being scolded by the locksmith when unlocking)

If there was a way to avoid the locksmith’s nagging, would you listen to it?

In fact, it is very simple, just replace the mechanical lock at the door of your home with a smart lock. Why is it said that changing to a smart lock can avoid nagging? Xiaochao reports from the front desk.

Why should we replace mechanical locks with smart locks?

As long as it is a lock, it has a lock core. As mentioned in the previous article, lock cylinders are divided into three types: A, B, and C. Among them, Class C lock cylinder is the strongest. Some mechanical locks and anti-theft door locks also use C-level lock cylinders, but the coverage rate is not very high. Many are still using Class A and Class B lock cylinders.

They all have a criticized shortcoming in mechanical anti-theft door locks - a key is required to open and close the door. Some manufacturers use low-quality metal that is prone to rust in humid weather.

Using keys to open locks is a habit that the Chinese people have continued for thousands of years. Every day when you open and close the door, you have to insert the key into the keyhole and turn it 1-3 times to fulfill the door's obligation to protect a family. The whole process is tedious and time-consuming. And it is inseparable from the carrier of the key. However, the habit of most people is to throw away the keys after entering the door, and then to search for the keys when they want to go out.

Until the emergence of smart locks, some people saw the opportunity and switched to smart locks. Say Goodbye to the key.

Or a story from the circle of friends

Yesterday morning, a girl who had a good time (Q9 was installed in her home on Xiaochao's recommendation) sent a message to Xiaochao saying: I was in a hurry to go out and forgot to lock the door. Followed by a long list of WeChat messages.

Seeing his friend in a hurry, Xiaochao didn't have the heart to joke with her.

"It doesn't matter! Do you think the Q9 I recommended to you only has unlocking functions such as fingerprint, face, password, and card swiping? It will automatically lock! You can absolutely rest assured! And it doesn't mean that there are so many unlocking methods that there is no key to unlock the lock. . We have also reserved keyholes for emergency settings!”
