Will the smart lock I bought for 200 yuan miss or overturn?

Ever since I was charged 200 yuan by a locksmith because I forgot to bring my key, I have sworn that wherever I live in the future, smart door locks must be installed on the doors.

Smart door locks are really a great way to save money and trouble for people who often forget to bring their keys. I recommend installing smart door locks to all families who have the conditions! The first point is that the smart door lock solves the problem of being unable to open the door if you forget to bring the key; the second point is that you can open the door remotely if you are not at home and someone is visiting or delivering a courier at home. There are even more advanced smart door locks that can monitor the outdoors and act as a cat\’s eye.

Although smart door locks are good, they are not cheap. Usually the well-known brands with installation services cost at least 700-1,000 yuan. The price of fully automatic smart door locks will be more expensive. After all, you can easily buy many entry-level ordinary locks on the market for 100-200 yuan, so for low-budget people, if you want them to accept a smart door lock that is five times more expensive, you really have to work hard mentally.

I searched the entire Internet and found a smart door lock that costs more than 200 yuan

What about it? Are there any smart door locks that are about the same price as ordinary door locks? Finally, after a price comparison search across the Internet, I actually found a smart door lock that costs only 283 yuan. Of course, this price definitely does not include door-to-door installation services. But even so, it is nearly half cheaper than the low-end locks from big brands we are familiar with.

01 Why buy such a cheap smart lock?

Many people will shake their heads when they see this super cheap price. Can a smart door lock at this price be used? In fact, before purchasing this smart door lock, I was full of doubts and uneasy, but my usage scenario determined that I had to choose it.

Door lock installation service provided by a door-to-door platform The price is 238 yuan

Due to renting and moving, it turns out that my smart door lock does not match the existing anti-theft door lock hole, so I can only ask the installation master to drill holes in the anti-theft door. The cost was too high (the door-to-door installation fee of the brand ranged from 200 to 400 yuan), so I decided to buy a smart door lock again. But since I am renting a house, in line with the principle of saving when I can, I have reduced the purchase budget of smart door locks to less than 500 yuan.

Although the budget is low, you still need to meet the basic purchase requirements. Firstly, the smart lock brand cannot be too bad, whether it is a professional lock brand or not, but at least it must be a formal and verifiable company; secondly, a lower budget means that there is no door-to-door installation service, so the door lock must be in line with the current The door holes are matched and support non-destructive installation, so you can install it directly by yourself after arrival, without additional labor costs. The third door lock must have basic fingerprint, password, remote unlocking and other functions, and can be correctly identified to prevent accidental unlocking and ensure basic security.

02 What does a 283 yuan smart door lock look like?

Based on the above purchasing principles, I started to search the entire Internet, and finally bought this smart door lock manufactured by Xijian Company on a certain website with tens of billions of subsidies. Although Xijian Company is not a professional lock company, it is considered a second- and third-tier brand in the field of sanitary ware. Therefore, when shopping online without being able to experience the actual product, the overall probability of choosing this product will be lower.

The quality of this packaging really cannot be compared with smart door locks worth more than a thousand yuan

Transportation I chose SF Express for my kindness, and the delivery speed was very fast. Like most smart door locks, the product packaging is a long and large box, but it can be clearly felt that the packaging of this smart door lock is smaller than The quality of smart door lock packaging boxes that cost around a thousand yuan is a notch higher. Of course, at such an ultra-low price, I can completely accept and understand it.

No matter how good the quality is But other smart door locks have a lot of this ultra-low-price smart door lock

Although the price of Xijian’s smart door lock is relatively low, other smart door locks should have There is almost no shortage of things: door locks, square steel, fixing screws, door side strips, unlocking magnetic cards, keys, etc.

The material of the lock body is indeed not as good as the previous door locks But the price should indeed match the quality.

Although it is only 283 yuan, the material of the lock body and handle are slightly better than expected. Of course, compared with the 3,000 yuan I used before There are still obvious differences between smart locks in terms of material, craftsmanship, and thickness of the lock body, but at this price, as long as it can lock the door without a key, why do you need a bicycle?

03 Is this ultra-low-cost smart door lock easy to install?

Already mentioned above?As mentioned before, the cost of door-to-door installation of smart door locks is usually around 200-400 yuan. If you can do it yourself, it is equivalent to saving a meal.

There is almost no big difference between the installation of smart door locks and ordinary door locks. As long as you have strong hands-on skills, you can install it yourself. If you really don’t know how to install it, you can also learn to install it through the official installation guidance video. I personally think that as long as your hands-on skills are not too bad, you can basically install it, but if you are not proficient enough to install it yourself, it may take a little more time.

If the door lock and the security door do not match, you need to pay the installation master to come and cut it.

The smart door lock can be installed by yourself, so why should you pay for a master? There are two reasons here. The first one is that you simply don’t want to install it and want to save money and effort. The second type is that the security door or door lock you purchased yourself does not match the keyholes and requires a worker to punch and cut on site.

A square steel that is too long to be included is included. It is estimated that 90% of doors require cutting to fit

Can this smart door lock be installed successfully by yourself? The answer is barely possible! The keyhole of this smart door lock should match most doors, so no additional drilling is required. But there is a very embarrassing problem. The merchant takes into account the difference in the thickness of the door in each user\’s home, so it directly provides the longest size square steel and fixing screws, allowing users to cut it according to the situation. (Usually, some expensive smart door locks will be matched with multiple square steels of different lengths, so that door bodies of different thicknesses can be installed directly without cutting the square steel).

Same as normal smart door lock installation process

The thickness of the screw is not very large. If it is too long, it can be cut directly with pliers. However, the thickness of the square steel is 5mm. Generally, users cannot cut it by themselves. They can only go to the physical store to find an angle grinder to help cut it. .So how did I finally solve the problem of the square steel being too long? The two springs provided by Arrow (maybe the merchant thoughtfully provided two springs considering that this kind of operation is relatively common?), which is barely installed.

Overall, I want it to be super. It is almost impossible to install it by yourself without worry, but you can still deal with the installation by yourself

04. Is this ultra-low-priced smart door lock safe?

First of all, in terms of hardware, this smart door lock uses a C-level lock cylinder. According to rumors circulating on the Internet, the C-level lock cylinder It takes 270 minutes to open, which is relatively safe in theory.

On the left is a 282 yuan smart door lock key On the right is a 3,000 yuan smart door lock key

The second is the small black box that has been circulated on the Internet before to interfere with unlocking. Through my own actual measurement, after the small black box is opened, this smart door lock There is no response, and the small black box cannot open the smart lock, which is relatively safe.

Small black box actual test: the smart door lock is not opened

Finally, fingerprints, passwords and other methods of identification cannot open this fingerprint lock after testing wrong fingerprints and passwords.

For us ordinary users, this is what we can think of. Under several test methods, this door lock has withstood the test and has no major safety issues.

05 How is your experience using this ultra-low-priced smart door lock?

Because it is a low-priced smart door lock, I don’t have much expectations for this door lock. After more than 20 days, After trying it out, I felt that there were not many surprises and not many shortcomings, and it was generally in line with expectations. My evaluation It is a qualified product at an ultra-low price. p>Low price Apart from the slight difference in hardware technology between smart door locks and mainstream locks, the main difference is actually the accuracy and speed of fingerprint entry and recognition.

The first is fingerprint entry. The author found that no matter which finger I switch during a single entry, the information can be entered successfully and the entry is displayed successfully. Although no one would do this under normal circumstances, it somewhat makes people question the safety of the product.

The first red light recognition was not successful. The green light recognition successfully unlocked the lock for the second time

Secondly, the fingerprint recognition. The fingerprint must be aligned with the reader, otherwise there will be a high probability of recognition errors. Compare it to the Yunmi Youth that was first used at home. In terms of recognition probability and speed of the smart door lock (699 yuan), this There is really no advantage (generally mainstream smart door locks are recognized and opened in seconds). Of course, such response speed and accuracy have little impact on the experience of normal users. I think it is acceptable. After all, I The requirement is not to bring a key

06. How to choose an entry-level fingerprint lock?

I think the choice of entry-level fingerprint lock isIt also depends on your own needs. For example, my needs this time are that the price should be extremely cheap and the product performance is acceptable. Then you can do the same as me and choose this 283 yuan product. But I have to say that unless it is a rental house, if it is a self-occupied house, it is still recommended to buy a slightly better door lock. At least it will feel more psychologically reliable after long-term use.

As for the purchase price and purchasing platform, I personally think that the current mainstream smart door lock packages are around a thousand yuan when installed. The mainstream unlocking method Generally covered. As for the shopping platform, JD.com is definitely the platform with the best security. If you want to find something missing, you can go to Pinduoduo and pay attention to the tens of billions of subsidies or go to Xianyu (Xianyu also has many merchants selling goods at low prices) Take a look.

In addition, you should pay attention to the following issues before purchasing a smart door lock. If it is a door lock that supports door installation, you need to confirm the thickness of the door, the size of the guide piece, the type of the lock body, etc. If door-to-door installation is not supported, you also need to consider whether the door lock can be installed without damage, whether the anti-theft door needs to be drilled, etc.

Finally, I would like to recommend some cheaper entry-level smart door locks. If it is just for the purpose of not bringing a key, entry-level smart door locks are also a very good choice. Of course When choosing a smart door lock, it is best to leave a key outdoors. After all, it is an electronic product, and no one can completely guarantee that there will be no problems.
