The door key hanging on my body has long been a burden. My family forgot to bring the key and had to wait until I got off work to go home. So I have to have a good key in my busy daily life. How can I get rid of the dependence on the key? The vehicle has entered and started without a key. You can open the door by hanging the key on your body, and the smart door lock that uses fingerprints and mobile phones to open the door has spread to many families. The progress of science and technology makes life easier, but the concern of smart door lock is safety, and electronic products will inevitably be cracked. Although Xiaomi door lock has a good reputation and C-level lock core is also a very high grade, what is the experience of the youth version after simple matching?
The package of Xiaomi Mijia Smart Door Lock Youth Edition is big and heavy, which is much larger than the real thing exposed outside. The delivery logistics is Debon Express, and the upstairs service is not provided. When I received it, the outer packaging was slightly damaged, but the internal accessories were intact.
The packaging is divided into upper and lower layers. The upper layer is the lock core, lock body, spare key, packaging box and accessory bag, which are packaged in separate cartons.
The lower floor is the exposed part of the main body of the door lock inside and outside. The slender figure of 385mm is much longer than that of the ordinary door lock, and the physical object is bigger and thicker than that seen on the commodity map.
In order to ensure the rigidity of the lock body and prevent it from being bumped during transportation, a separate packaging box is provided, in which the B-class safety lock body is firmly embedded, and the door gusset plate and fitting screws are also beside it. The lock body is very heavy and has an all-steel structure.
The lock body is the core component of the door lock. This Xiaomi Smart Door Lock Youth Edition adopts the universal lock body of Japanese standard 6068, which is more stringent. The smart lock body has a built-in clutch motor, and the overall safety is Class B. Among the two safety levels, Class B is higher. According to the standard, Class A cannot be opened by technical means within 5 minutes, and Class B is 10 minutes, so that it can be handled in the process of violent unlocking. The clutch motor of the door lock is arranged inside the lock body, but not in the front and rear exposed panels. In this case, even if the front and rear panels are damaged by violence, the door lock cannot be opened. The structure with hook on both sides is the upper and lower auxiliary door lock. Because the installed door body is old, the structure of the hook between heaven and earth is somewhat worn, so it is not installed. The main lock tongue is also designed to prevent the use of small cards to open the door. In some spy war movies, we have seen the technology of opening the door with small cards.
Under the main lock tongue, the ordinary lock body has three square lock tongues with mechanical structure for locking, and the bottom is the lock tongue with mechanical structure, which is a safer scheme. After all, electronic equipment is always at risk of being cracked. As long as the lock tongue is locked internally, no matter the mobile phone, password or fingerprint, it will be more reassuring to develop the habit of locking the door before going to bed every day.
Another relatively small independent box is a replaceable C-class lock core, battery fittings and installation package. The lock core can be replaced. It is a simple and easy method to replace the lock core in order to prevent the predecessor from opening the door again when changing the owner. Therefore, the lock core is required to be brand new, and a separate package is adopted. On the back, it is suggested that you can contact customer service to replace it if the package has traces of disassembly. The C-class lock core is the lock core with the highest safety level under the current standard. This Xiaomi Smart Door Lock Youth Edition designs the lock core inside and requires a key to be inserted directly into the lock core to open the door. This is the reason why the straight-in lock core is safer. Although some smart locks are also equipped with the C-class lock core as standard, they are not straight-in, and the electronic structure is used for secondary unlocking, which increases the risk of electronic unlocking.
Although smart door locks usually don’t need keys, just in case, Xiaomi Smart Door Lock Youth Edition is equipped with two spare keys. Even if the security of electronic products is increased, it is inevitable that there will be a small probability of failure, and it can be saved in other places outside to some extent. Unnecessary troubles can be solved.
The panel of Xiaomi smart door lock is a simple black matte APPearance, with a heavy hand feeling and a side thickness of 26 mm. On the left side of the rear panel is a mechanical anti-lock knob, and on the right side is a battery box, which is equipped with four double deer batteries. Xiaomi smart door lock Youth Edition is manufactured by Luke, with a theoretical battery life of 10 months. There is no battery display, and there is a low battery reminder function on the mobile phone app. The dot on the battery compartment is the reset button of the door lock, and the battery compartment has a large opening area and is reserved.
The front panel is the exposed part, on which is the conventional password input panel. The whole frame is made of alloy structure, and the panel is pure black, which increases the concealment. Only when the panel is touched, the digital backlight will be displayed, and when the battery is low, it will flash to remind you to replace the battery.
The handle is equipped with the concave function of fingerprint recognition, which is exhausted with some mobile phones with fingerprint recognition. Users can identify fingerprints to open the door lock every time they press the door handle. One-step operation avoids that some smart locks need two hands or two steps to open the door when fingerprints are separated from the handle. Many door locks are inserted with keys to turn the door, and the door handle is fixed. Although the push-down door handle may shorten the service life of the door handle, it can be unlocked only by identifying fingerprints once, which can save electricity to a certain extent.
The speaker is at the bottom of the external panel, and there are voice prompts for correct and incorrect fingerprint input. There is a Micro-USB interface at the bottom, which can provide backup power input if the battery of the door lock is exhausted. You can open the door lock to replace the battery by connecting the charging treasure, which is not easy to detect at the bottom. Although it is inconvenient to plug in and out, it is prepared. Equipped with a restart switch, it is necessary to know that the restart switch will not reset the fingerprint and password, and will not affect the security of the door lock.
There is a circle of anti-slip sealant sleeve on the back of both panels, which is better enough to be fixed on the door. The connecting line between the panel and the lock body is Type-C interface, and the thickness of the steel plate of the whole panel is compensated, which makes the appearance fuller. The overall workmanship is worthy of recognition.
Installation service experience
Mijia provided a good installation service, and he is a local professional installation master. He installed Xiaomi himself and sold various brands of smart door locks. I believe the after-sales service is also very professional. Through chatting, Xiaomi’s reputation and selling price are all positive. He directly applied for home installation service on Mijia’s App, and he can apply according to the SN code on the package. The service response is very fast, and customer service will contact him to install it within a few hours, and the appointment process is also smooth.
Before making an appointment, based on the idea that I am also very good at installing a computer myself, I saw the built-in punching drawings, and I really tried to DIY myself, but when it comes to using professional equipment such as angle grinder, I don’t have it at home, so I will learn it when I install it.
Before the master came, he contacted me in advance and asked to take photos of the side of the door, so as to take the corresponding tools when going upstairs. The whole installation process lasted about an hour from the beginning of installation to the test of opening and closing the door. The door body has been an old door for more than ten years. Some parts of the switch have been slightly deformed for many years, and some positions need to be cut during the installation process. After some column adjustments and repeated debugging, the smart door lock is finally installed. Compared with the original door lock, the smart lock is thicker, but the layout is relatively reasonable. Later operations need to open the Mijia App in the mobile phone for operation.
In the process of debugging, the battery needs to be buckled and reinstalled, and the door lock will sound an alarm. The first thing to do after connecting the APP is to prompt for an upgrade. In the process of waiting, the installer is patient. After I set it up, I will repeatedly test the door opening and locking, and I will leave after debugging all the locks, locks, fingerprints and passwords. I also took photos of the door lock and uploaded it. Then I will be prompted by a text message from Mijia that the installation is complete, and I will give the installer a verification code before the installation is over.
Then enter the fingerprint, the operation is very simple, and the fingerprint of the left thumb is set for the family, which is more convenient. The password can be set with a one-time password and a periodic password. The periodic password is suitable for hotels and hostels, and it can check out without contact, which can increase the security of the door lock. And every time the door lock is opened, there will be a record showing when the owner of the fingerprint opens the door lock, but it is necessary to connect the Bluetooth of the mobile phone.
In the actual experience, fingerprint entry is as convenient as a mobile phone, but you need to put your finger in the exact position when opening it, otherwise you will have to wait for 5 minutes to enter it again if you make five mistakes, during which you can enter a password to unlock it. The experience of smart door lock is very good. Five unlocking methods have been tried one by one, and the most common one is fingerprint unlocking, which is very satisfactory to the family, especially the child can open the door himself. Every time he goes upstairs, he will try to open the door, and if someone opens the door first, he will close the door and try it again.
