After replacing 3 sets of smart door locks in 7 years, I finally realized: high-end locks do not mean safer

My security door still has a chance to change the lock.

This is not what I said, but what the lock installer said. In the past seven years, my house has had three sets of locks replaced, and each time I installed a lock, I needed to drill or expand a hole in the door. Today\’s anti-theft doors can hardly hold the locks. The installer said that the best they can do is replace a set of locks, otherwise the door will have to be replaced.

The three sets of locks in my house range in price from a few hundred yuan to five to six thousand yuan now. I met a friend today and asked me after hearing my story:Why do you pursue high-end locks?

I seem to have never thought about this issue, I just take it for granted that more expensive locks must be better. But is this really the case?

I want to say: safety is more guaranteed

But: all locks are C-grade lock cylinders

The anti-theft levels of anti-theft door locks are divided into three levels: A, B, and C. All smart door locks have the highest level, C. This means that no matter whether it is a smart door lock worth a few hundred yuan, it is still a smart door lock. Smart door locks costing several thousand yuan each have the same technical difficulty in unlocking.

Smart door locks also have the possibility of electronic unlocking, but the required anti-theft capabilities are now standard:

•Biometric fingerprint unlocking, all smart locks have;

•Virtual password unlocking, available in all smart locks;

•Independent internal and external lock bodies, all smart locks have them;

•Violent breaking alarm, all smart locks have them;

•Dual-chip encryption, all smart locks have…

In other words, more expensive locks do not mean more secure. And think about it from another perspective: There is no need for people with lock-picking skills to do petty theft; besides, we ordinary people have nothing to steal at home.

I think Said: More convenient to use

But: the most commonly used unlocking method is fingerprint

The biggest difference between high-priced locks and low-priced locks is \”function\”, just take Let’s talk about the unlocking methods:

•Opening the lock inside the door, a lock worth several hundred yuan only\”Press the handle\”This way. Just add some money and you canInstall a button on the door lock, and press the button to unlock. With a little more money, you canInstall a sensor on the door lock, the lock can also be unlocked by holding the sensor with your hand.

•Unlock the door, a lock worth several hundred yuan can passFingerprint and passwordTwo ways. High-end locks, generally withFace recognitionFunction – Automatically identify outsiders when they approach the door lock, and automatically unlock the door after successful identification.

But to be honest, these two upgrades are not perfect:

↑Lock with sensor, the button will become very small

In the door unlocking mode, The sensor is the most inconvenient. For example, if I hold something in my hand, when opening the lock, I must first put the thing on the ground and then hold the sensor with my hand.

In the door unlocking mode, The so-called \”face recognition\” is just a gimmick. The recognition rate is too low. If you put on makeup or wear a mask, the recognition will fail. If someone passes by the door, the alarm will sound.

I want to say: better looking

But: the lock body has little impact on the door

I used to think that smart door locks can definitely enhance the appearance of anti-theft doors. Later I found out that I was wrong: it was dark in the corridor, and I could only tell whether you installed a smart lock, but I couldn\’t see the details of the smart lock at all.

Take my home as an example:

Although my lock was cheap at first, it had a golden surface and a large glass panel that was very bright. Later, a set of black locks were replaced, and they were no longer noticeable. After replacing it again, not only was it black, but the glass panel was also gone, making it completely black.

\”Of course, the \”glass panel\” is not a good thing. The glass on the password disk is easy to stick to fingerprints, allowing someone to guess the password of our home. So the panel It is still necessary to upgrade to matte surface and metal materials.\” Speaking of this, some people may still think: black is black. Well, you haven’t lost anything!

You are too naive to think so. I actually lost it: high-end locks often have very expensive materials. For example, the door locks at my house are made of pure copper and solid wood. Materials——

These materials have no practical meaning and are simply for good looks.

↑The more expensive the lock, the higher-end the material

So since the door lock has such a small impact on the appearance of the door, why should I pay for these high-end materials? The key is not to pay. No way: high-end materials have become standard features on high-end smart locks, and you don’t have to pay for them.

Obuchi summary

Smart door locks worth a few hundred yuan are indeed slightly inferior in terms of security, such as glass combination disks, handle unlocking methods, etc. But there are no smart door locks worth more than a thousand yuan. There is no need to upgrade to a high-end product. Therefore, the most recommended price for buying a smart door lock is 1,000 yuan to 3,000 yuan.
