The first step is unpacking. Xiaomi Mijia Smart Door Lock Youth Edition has a net weight of 2.55kg, which is really heavy. The products are packed in sturdy and environmentally friendly cowhide cartons, with the logo of Xiaomi and Mijia printed on the surface, and a handle on the top for easy handling.
When you open the package, you can see that the lock body and accessories are packed in separate boxes, which are firmly fixed. In addition, a large number of foamed cardboard is used as space and buffer in packaging to ensure the safety of product transportation.
The lock box includes lock body, door buckle plate, door buckle box and screw bag, which are arranged neatly.
The lock body of Xiaomi Mijia Smart Door Lock Youth Edition looks similar to that of ordinary door locks. It is divided into upper, middle and lower lock tongue areas and five lock tongues, which correspond to each other from left to right: 1 independent mechanical lock lock tongue, 3 main lock tongues and 1 oblique lock tongue. The lock tongue is all made of stainless steel.
The two small hooks at the upper and lower positions of the lock body are used to install the heaven and earth hooks, which means that this kind of door lock can be applied to the security door with the heaven and earth hooks. However, when installing the door lock, the installation master suggested not to install it even if there is a hook between heaven and earth, because the hook between heaven and earth is easy to age and corrode, and there is a risk that it will not retract or even fall off normally when unlocking, resulting in the inability to open the door. Another advantage of not installing a hook is that the load of the lock body is less, and it is more labor-saving when opening the door, especially suitable for the elderly and children with small strength.
In addition, I found that the lock body has a small tail, which I have never seen before on the smart door lock. It turns out that the lock body of Xiaomi Mijia Smart Door Lock Youth Edition has been upgraded with electronic clutch, and this small tail is the wiring of electronic clutch. The electronic clutch lock body adopted by Mijia Smart Door Lock Youth Edition is difficult to unlock even if the door lock panel is damaged by violence, which can effectively prevent technical violence from unlocking. With the high-hardness all-metal lock body, it has reached the B-class safety level.
The quality of door buckle plate and door buckle box is good. The door buckle plate is made of stainless steel, and the door buckle box is transparent in plastic. But if the door gusset of the original door can be used with the new door lock, there is no need to replace it.
The accessory box contains a lock core, two emergency keys, four No.5 alkaline batteries and an accessory package, in which the lock core and the emergency key are all plastic-sealed, and the package must be destroyed before the user receives the product to avoid the risk of the emergency key being stolen or copied, and the details are carefully considered.
The lock core of Xiaomi Mijia Smart Door Lock Youth Edition adopts all-copper C-class straight-in lock core, which is the lock core with the highest security level at present. The plug-in lock core runs through the lock body, which can remain intact even if the door lock panel is damaged. It is more reliable than the common B-class lock core on the market.
There are two emergency keys. The keys are folded. Unlike ordinary serrated keys, these two keys are designed with side grooves, which should be more difficult to copy. Emergency key, just in case. Smart door locks are electronic devices after all, and may encounter unexpected situations such as battery failure. It is safer to keep the original mechanical unlocking method.
Xiaomi Mijia Smart Door Lock Youth Edition panel is painted black, and the frame material is made of high-strength alloy, which is impact-resistant and durable. The panel is divided into a front panel and a back panel. Because the door lock itself does not support changing the direction of the handle, you need to choose whether to open the door to the left or right when buying. In addition, this lock does not support overlord lock body at present (it feels like the tradition that Mijia door lock products do not support overlord lock body in the early stage of listing).
Let's look at the front panel of the door lock. The front panel is the facade of the smart door lock. The front panel of Xiaomi Mijia Smart Door Lock Youth Edition adopts a simple and classic smart door lock shape. The upper part is a hidden capacitive touch password keyboard with a built-in white LED status indicator. When the screen is closed, almost nothing can be seen, it is hidden, and the password display needs to be clicked or touched to light up.
Optical fingerprint identification technology, which was the mainstream in the market a few years ago, will be completely replaced by semiconductor fingerprint identification technology. The semiconductor fingerprint is easier to identify and detect the living fingerprint. This technology mainly responds to the real living fingerprint through the skin temperature and skin capacitance, which can better prevent the fake fingerprint film and orange peel from cheating and unlocking, and is safer and more reliable. The fingerprint identification area of Xiaomi Mijia Smart Door Lock Youth Edition is integrated with the door handle, and the circular area is slightly concave, which is ergonomic. When holding the door handle, the thumb naturally touches the fingerprint recognition area to realize one-step unlocking. According to official data, the fingerprint recognition rate is as high as 97.4%, and in most cases, the lock can be unlocked with one recognition.
This oval area in the lower half of the front panel is the invisible keyhole of the door lock, which can be rotated and opened by gently pressing the bottom of the cover plate. Strong concealment, not easy to be found, integrated design will not fall. Further down the keyhole is the mijia logo. Although it is a product of Luke, I have to say that changing the trademark of Mijia is a plus item. After all, many people have the same plot as me, and prefer to collect and use products with Xiaomi and Mijia logo.
The Micro USB interface under the door lock is an emergency power port. Although there is a low battery reminder on the panel, it will flash when the battery is low, and there will be a push notification and a battery display in the Mijia app. However, once the battery is really dead, you can use the charging treasure to temporarily access the emergency power supply port to solve the urgent need. On the left and right sides of the Micro USB interface, there are speakers (door lock prompt tone and emergency alarm bell) and emergency restart button (restart the door lock system when the intelligent system is slow to respond).
Turn to the back and look at this thick rubber sealing strip, which is on the back of the front panel and the back panel. When installing, the door lock panel can be closely attached to the door without leaving gaps, and the workmanship is very meticulous.
Next, let's look at the back panel. The top half of the back panel can push the cover upward to open it. Inside is the battery compartment of the door lock. It uses a liquid-proof design, and the battery life is not clear. According to my past experience, it should not be a problem to use 1 year or even longer.
The door handle of Xiaomi Mijia Smart Door Lock Youth Edition adopts German double bearing structure design, which can ensure that it will not sag for ten years. The round button on the handle of the rear panel is a cat's eye lock button, which needs to be pressed when opening the door indoors to prevent the door from being pushed down by damaging the cat's eye and hooking the door handle outside. In addition, the anti-cat-eye lock switch can also be used as a child lock button, which is suitable for families with children or cats and dogs, and can prevent children and cats and dogs from opening the door by themselves.
A cat-eye lock switch is designed behind the handle to set whether to use the cat-eye lock function, which gives users free choice. If the security control equipment such as smart cat's eye is installed at home, or the door has no cat's eye hole, it is completely unnecessary to use the cat's eye lock, and the steps of pressing the switch every time are reduced, making the operation easier.
The big round knob in the lower half of the rear panel is an independent mechanical anti-lock knob. Both the front panel handle and the rear panel handle can be locked by lifting, but if you want to be safer, you can rotate the anti-lock knob indoors to eject independent anti-lock bolts. Once locked, people can't open the door normally outdoors anyway, so they must be removed by violence.
After unpacking, the product is introduced here. Here is the installation link. Xiaomi Mijia Smart Door Lock Youth Edition provides free installation service. You can make an appointment for installation by scanning the QR code on the manual or calling customer service. When installing, you must first remove the old door lock, and then install the new lock body and lock core in place.
Don't think it's as simple as just removing the old lock and replacing it with a new one. In the installation process, according to the actual situation of the door, use professional tools to expand the opening and correct the size of the fittings. This is a technical job, but fortunately, the installer is professional and skilled. These are not problems, and problems can be solved perfectly. Love it!
After installing the lock body and lock cylinder, fasten the front panel and rear panel, connect the cables and install the battery. Xiaomi Mijia Smart Door Lock Youth Edition is installed, which is just a comparison with the ordinary door locks of neighbors. The new door lock is obviously more valuable, which shows the sense of technology and better security of the times. Once used, it can never be replaced.
With a flick, the password area will be lit up, with white characters on a black background, which can be seen clearly. Xiaomi Mijia Smart Door Lock Youth Edition supports five unlocking methods: fingerprint, password, temporary password, mobile phone Bluetooth and emergency key. It also supports remote generation and sending of one-time passwords, which can cope with various usage scenarios. In terms of security, Xiaomi Mijia Smart Door Lock Youth Edition has built-in Mijia security chip, which supports multiple encryption authentication, protects data security and resists electromagnetic interference.
Xiaomi Mijia Smart Door Lock Youth Edition, as a smart door lock, can naturally access Mijia app to realize the Bluetooth unlocking function, while the process of inputting fingerprints is displayed in a graphical interface with a voice reminder, which is vivid and vivid. If there is a Bluetooth gateway at home, the door lock can also be linked with other smart home devices at home, such as automatically turning on the hall lights and closing the curtains when you go home to open the door at night. Moreover, it can also realize remote unlocking reminder and remote door lock prying alarm, and you can also install smart cat eyes when sitting in the office.
Generally speaking, Xiaomi Mijia Smart Door Lock Youth Edition is a mature smart door lock product, which has five unlocking methods, such as in-line C-class lock core, German double-bearing door handle, alloy panel, independent cat-eye switch, independent mechanical locking device, built-in Mijia security chip, living fingerprint and remote one-time password. And support the linkage of Mijia equipment, enjoy free installation service and three-year free warranty, and comprehensively upgrade the electronic clutch lock body. Compared with the smaller Mimijia smart door lock, the main change is only to reduce NFC, which is of little significance to ordinary users or even a little chicken ribs, and the cost-effective advantage is more obvious. For mass users, Xiaomi Mijia Smart Door Lock Youth Edition is undoubtedly a good choice because of its excellent quality, complete functions and affordable price.
