As early as two years ago, Xiaomi announced a new crowdfunding product: Luke Smart Door Lock Classic through a product APP. At that time, the price of 1,699 yuan attracted people’s crazy buying, and now the Luke Smart Door Lock Classic2 generation, What kind of surprise will it bring us?
Luke Classic 2S Intelligent Door Lock
Today, the author got a Luke Classic 2S smart lock, so let’s take a look at what kind of sparks the new generation of intelligence and lock will collide with.
First, talk about appearance
Open the outer packaging of the carton of Luke Classic 2S smart lock. First, you will see the pure black inner and outer panels, and take out all the accessories. You will find that in addition to the inner and outer side panels, there are also installation opening drawings, installation instructions, eight 5th (AA) batteries, lock body, two C-class mechanical keys, instructions for use, warranty cards, network cables, screws, square steel, springs and other accessories needed for installation.
Eight batteries can be installed.
Appearance display
It is worth mentioning that the internal packaging is very intimate, and there are a large number of plastic sponges in the packaging box, which fully guarantees the wear and tear of the smart lock during transportation.
The inner and outer panels with a thickness of only 21mm are made of high-quality zinc alloy, which looks very beautiful with the traditional rotary handle design.

There is also a bar indicator light hidden in the upper part of the password input area of the outer panel. When we unlock the door, the indicator light will remind you by color and report the current door lock status to you.

In addition, in the lower part of the password input area, there are also low battery indicator lights and NFC identification areas. At the bottom of the panel, there are emergency restart buttons, horn holes and Micro USB emergency power interface, which fully guarantee the normal use of daily door locks.

Having said so many appearances, let’s experience it with the author!
Second, talk about the unlocking experience
Through the instructions, we know that Luke Classic 2S smart lock has six unlocking methods: fingerprint unlocking, Bluetooth unlocking, password unlocking, NFC unlocking, temporary password unlocking and physical key unlocking.
Just saying so many ways to unlock, is it good or not? Let’s experience it one by one.
Fingerprint unlocking experience
Fingerprint unlocking is an essential unlocking method for all smart door locks at present. The fingerprint identification of Luke Classic 2S smart door lock is set at the handle shaft. When unlocking, you only need to hold the handle with one hand, and the fingerprint identification will unlock the door within 1 second. The whole unlocking process is very smooth.
Fingerprint recognition area
In addition, the hidden bar indicator light will tell us whether the verification is successful by color. When the indicator light is green, it proves that the verification is successful, and we can press the handle to open the door and enter the house. When the indicator light shows red, the verification fails.

With the reminder of the indicator light, it is easy and convenient to unlock it at a glance.
Bluetooth unlocking experience
When it comes to Bluetooth unlocking, of course, you need to use a mobile phone. The mobile phone turns on Bluetooth, and then connects with the smart door lock through Mijia APP. When you come to the door, you can open the door with just one button. When you open the door in this way, in order to ensure the safety of your home, it is best not to try to unlock it with Bluetooth APP far away from your home.

With this function, we can all come to our side without moving half a step.
Password unlocking experience
Luke Classic 2S smart door lock can set a six-digit unlock password through Mijia APP.
When using the password to unlock, we need to light the password input area first, and then we can enter the password. When entering the password again, we should check the surrounding environment to prevent the password from leaking and causing unnecessary losses.
Unlock the actual password
In the experience, we found that Luke Classic 2S smart door lock also supports virtual password input. After testing, Classic 2S supports virtual password (including correct password) with a maximum length of 16 digits.
In addition, we can also remotely generate a one-time unlocking password through key management, so that even if no one is at home, relatives and guests can wait directly at home.
Experience unlocking with one-time password
In the experience, the randomly generated one-time password can only be used for opening the door once within the effective time.
NFC unlocking experience
NFC may be the most commonly used thing for people to swipe their cards in traffic. Unexpectedly, Luke Classic 2S smart door locks can be unlocked by NFC.
NFC card
After adding the corresponding NFC card, watch or bracelet to the mobile APP, it can be used to unlock. When unlocking, just stick the device with NFC function on the identification area, the indicator light will show green, and press the door handle to open the door lock.
Mechanical key unlocking experience
Luke Classic 2S can directly open the door lock by inserting the key and rotating it clockwise by 90, which changes the previous style and avoids the phenomenon of forgetting the key in the keyhole.

After the door is closed, the locking bolt will automatically pop up to lock it, thus avoiding the potential safety hazard of following the door.
Third, talk about safety
In terms of security, Luke classic 2S smart door lock has set up various alarm modes: alarm for abnormal locking of the main lock tongue, alarm for left unlocked, alarm for lock picking, low-power alarm, alarm for door not being closed properly, alarm for continuous wrong password input and alarm for continuous wrong fingerprint input.
The prompt door is not closed properly.
We simulated several common scenarios:
Scene 1: The main locking bolt is locked abnormally, that is, when it is not pressed in, the door lock will give an audible and visual alarm, prompting that the door is not closed properly.
Scenario 2: Incorrect passwords are entered continuously. In the case of incorrect passwords for five times in a row, the door lock gives an alarm, and it is impossible to enter any more passwords for five minutes.
Scenario 3: Input the wrong fingerprint password for 10 times in a row, and the result is the same alarm, and the door lock will not be unlocked by fingerprint within 5 minutes, but other unlocking methods can be used normally.
Improper operation will give an alarm.
After the test, it is not difficult to find that the three modes, namely, the lock bolt locking alarm, the left-unlocked alarm and the door not closed alarm, are actually in the same state-the door is not closed, that is, the main lock bolt is not closed.
Abnormal alarm of lock tongue
In this way, in fact, there are only four kinds of alarms: door opening alarm, lock picking alarm, low power reminder, and wrong password/fingerprint alarm.
All of the above are outside the door, so what about the safety measures inside the door?
Luke classic 2S smart door lock is equipped with a cat’s eye protection device, which can lock the handle with a flick of the switch, without worrying about the way of unlocking from the cat’s eye. Compared with the previous generation push-button design, this toggle switch is obviously safer.

In addition, there is a knob-type anti-lock design, which can be achieved by gently pressing and rotating. The operation is simple, and the misoperation of children can be effectively avoided.

Fourth, talk about common problems
In the process of using smart door locks, it is inevitable to encounter some common problems, such as: battery dead, mobile phone lost and so on. Now, let’s see how to deal with these problems together.
1. What if there is no electricity?
When the power of the door lock is less than 10%, the door lock and the APP will prompt to replace the battery; Even if you forget to replace it and the battery is exhausted, you can use the USB power supply at the power port at the bottom of the outer panel for emergency power supply to open the door, or use the mechanical key to unlock it.
2. What should I do if my mobile phone is lost?
Before use, you can set an independent password to enter the door lock device interface in the mobile phone Mijia APP. Even if the mobile phone is lost, you can’t enter the door lock control page without a password. When we buy a new mobile phone, download Mijia APP and login password, we can use it simultaneously.
3. What should I do if the fingerprints of the elderly are not easy to use?
Smart door locks are supported by people aged 7-70, but their fingerprints are badly worn and may not work well. For users with serious fingerprint wear, any fingerprint device is actually not very good. At this time, the user can unlock the door with a password or wear a mechanical key to open the door.
4. What should I do if I lose my NFC card?
When the NFC card bound to the smart door lock is lost, we can connect the door lock via Bluetooth, delete the NFC card in the APP, and add a new NFC card after deletion. Easy to operate, you can rest assured that your home is safe.
5. What should I do if the main locking bolt does not pop up automatically after the door is closed?
Try to close the door again to see if the main locking bolt can pop up. If it still fails to pop up automatically, we need to check one side of the door buckle plate to see if there is an obstacle. If we still can’t find the cause of the failure, don’t worry, just contact the after-sales department to deal with it.
6. What should I do if I feel that fingerprint reading is a bit slow?
If the response is slow after being installed for a period of time, consider that the fingerprint collection window will be stained with dirt or wet on the surface after being used for a long time. Wipe it gently with a dry soft cloth. Note that it is a dry soft cloth.
5. Write it at the end
Luke classic 2S smart door lock has no doubt in appearance value, supports multiple unlocking modes, is also very convenient to use, and can meet daily needs in unlocking response speed. In addition, the security aspect also has a good performance in the test.
With the development of 5G and the rapid popularization of smart homes, smart door locks will become an indispensable part of smart homes. When you open the door, you start the linkage of the whole smart home, and when you close the door, you will all close it. This is what smart life will look like in the future.
