Is fingerprint lock really safe and reliable?

Any publicity must be the best. Our family has never used it, but I know an uncle who locks it. Because he has a good relationship with my father, we will have dinner together. I once said that because he was locked out of the door and there were old people at home, he wanted to buy a smart fingerprint lock or something. This uncle advised me not to buy it. He has to remove several smart locks every month, not that kind of power failure.

Of course, it's not that nothing is good. Personally, I always think that electronic products are just a matter of luck and technical maturity. Professional companies do professional things. Anyway, I have no idea of buying a smart lock now. Just use the traditional lock, hahaha.

Is the world safe? Security and reliability are relative.

As the saying goes, "if you are not afraid of thieves stealing, you are afraid of thieves thinking." No lock can lock the coveted heart of others.

My front door uses a fingerprint lock. From considering replacing the traditional key lock to the fingerprint lock that has been used for some time, let me talk about my feeling of safety and reliability.

As the saying goes, "a key matches a lock", the traditional key lock only recognizes the key but not the person. Anyone who has the key can open the lock.

If the owner accidentally loses the key, there is a safety hazard.

Moreover, the traditional key door lock has a simple structure, requires a little experience and skill, and can be opened with simple tools.

For example, those lock openers are not a science and engineering student in the university of high flyers, 2 1 1 985, and they are not strange talents. They are just ordinary people, just mastering a craft.

For example, I have seen someone demonstrate with my own eyes that a seemingly solid lock can be opened from the crack of the door in a few minutes with a wire and an ID card.

The hotel room has a chain lock, and it is precisely to consider adding a double insurance.

Even with atomic lock, the safety factor has been improved, but the basic principle is the same as the traditional key lock.

The biggest security of fingerprint lock is to identify only fingerprints, which are preset by the owner.

This eliminates the security risk of obtaining the traditional door lock key to open the door.

And everyone's fingerprints are unique, so don't worry about outsiders having duplicate fingerprints to open the door.

So in this sense, fingerprint lock is safer and more reliable than traditional key lock.

In fact, thieves can't move, and they don't want big items such as home appliances and furniture.

There are no gold and silver antiques and a lot of cash at home, even if thieves patronize, they will make a trip in vain.

However, I'm afraid that the master and the thief accidentally meet at home, scaring the children and the elderly. Even if we meet in a narrow way, there are likely to be casualties.

Therefore, installing door locks in society now often adds a layer of security psychology.

There are children who go to school and old people at home.

They accidentally lost their keys. I also forgot my key when I was in a hurry to go out several times, so I couldn't get in.

So I considered not only safety, but also the convenience of life, and later I changed it to fingerprint lock.

Of course, fingerprint locks also have congenital defects.

For example, the old man has a lot of cocoons on his hands, and sometimes he can't recognize the door lock. Or there are sweat stains and oil stains on your hands, which will also affect recognition.

If it cannot be recognized for three consecutive times, the system will automatically lock it, and it will take some time to try again. This is very embarrassing and annoying.

So, I bought a dual-function door lock with fingerprint and password. If sometimes the door lock can't recognize fingerprints, enter the password to open the door.

Of course, if the old man's fingerprints are sometimes unrecognizable by the door lock, his memory is poor, and he forgets his password, he still can't get into the door.

At this time, you can only call the child to ask for the password. But if you happen to forget your mobile phone when you go out, it will be embarrassing!

On the other hand, there is no absolute safety and reliability in the world.

Since fingerprint lock is a product of science and technology, and it has been mass-produced and popularized, its principle is no secret.

As the old saying goes, you can lock a gentleman, but you can't lock a villain.

I believe that people who are interested in breaking into houses have studied or are studying fingerprint locks.

In fact, the basic principle of fingerprint lock is the same as opening a mobile phone with fingerprints.

To put it bluntly, whether it is a fingerprint lock or a higher-tech facial recognition lock, it is still a lock. If the thief wants to crack it, he only needs a little more effort than the traditional key lock.

So in the final analysis, it is still necessary for the owner to pay attention to the safety of the portal and strengthen anti-theft measures. Don't put cash or valuables at home to avoid losses.

If you are unlucky, a clever thief will break the fingerprint and lock the house, so his result will be empty-handed.

As long as the owner is okay, it is also a big deal to spend money to change the lock.

Not to mention, is it safe or not? Fingerprint locks are really convenient. There are old people and children at home, especially children who don't need keys to unlock at all! It's really convenient to open it with your finger! Let's talk about the bad places!

One of the most feared problems of an electronic product is power failure! Our neighbor's house is like this. We forgot to charge, so we couldn't get in. Later, we came to my house to call the unlocking company and let it open the door.

Two. Everyone knows that fingerprint identification becomes insensitive after a long time. We bought a mobile phone for thousands of dollars, and after a long time, fingerprint identification became insensitive, let alone a fingerprint lock for three or five hundred dollars. Of course, there are better fingerprint locks for thousands of dollars.

Three. Some fingerprint locks can only set three or four fingerprints. If your family is very big, it is impossible to use them all, so this one is a bit pitted.

Let's turn it back and talk about security. What kind of lock you use is a psychological effect. A professional locksmith can open any lock in one minute.

Anyway, fingerprint lock has the advantages of fingerprint lock, and traditional lock has the advantages of traditional lock. It depends on your choice.

Thank you for your invitation.

Answer: The security of fingerprint lock is relative, not absolute. One of the following situations will be very troublesome once it happens.

In a mansion in the rich area of Beijing, the doors of every household are fingerprint locks.

First, it is inconvenient for the elderly to operate. After the finger is pressed to unlock, there is no response. I don't know why. Later, I learned that it was because your finger fingerprints were blurred, and you couldn't open the lock without recognition.

Second, it can't be turned on because of power failure.

Third, the operation is not standardized and it cannot be opened. Then let the person who uses the password unlock it. Just press it, the alarm suddenly sounded. Ouch ... ouch ... ouch ... then there was the stampede upstairs, and that was the security guard.

At this time, I hurriedly called my son to let him hear the sound here. He did say calmly, "Never mind. After playing 15 minutes, there is no sound. " The result is really like this. /kloc-fully recovered after 0/5 minutes.

In fact, how safe is the lock now? Depends on social security. What lock can stop a smart human? Fingerprint lock is convenient. You don't have to take your keys when you go out, and you won't worry about losing them. But some people in the comments said that the fingerprint lock was broken. Here I would like to remind everyone to buy a reliable one, preferably one that others have used for a while.

There is an old saying that a key opens a lock.

But personally, this is for a gentleman. For those gentlemen on the beam who specialize in stealing doors and picking locks, they can still unlock without a key!

So there is no absolutely safe lock in this world. As long as those people are given enough time, I believe there is no lock that they can't open. Of course, it also includes fingerprint locks that are absolutely safe and reliable in the mouth of some merchants.

In my opinion, compared with traditional locks, fingerprint locks are nothing more than the benefits of carrying a key with you. Especially for those who forget, often lose their keys or forget to bring them, fingerprint lock is definitely their gospel.

In addition, I don't think fingerprint lock is any better than traditional lock.

I'm telling you, it's not reliable, because it's very troublesome when there is no electricity. Without electricity, it's just a piece of scrap metal. My family ran over one before, and it wasn't cheap either. I won't name the brand, because I worked outside for a while before, and I can't get into the back door when I come back. I was so angry that I cried. Finally, it took the locksmith 100 to get in. In my opinion, anything that uses batteries is unreliable. Because the battery has not developed greatly, you will cry when it is dead.

I swear to god, I advise you never to use fingerprint lock, which is the most unsafe lock.

We can imagine that if it is a key lock, if a thief wants to enter, he will only open it in two ways, the first is skill unlocking, and the second is violence unlocking. But what about smart fingerprint locks now? In addition to technical unlocking and violent unlocking, there are many unlocking methods, such as fingerprint, code scanning, credit card, password and so on. One more unlocking method will increase the risk of unlocking, and many netizens may retort that it is convenient to lock fingerprint locks! You really don't need to bring a key, but the biggest purpose of our lock is to ensure the safety of our home. What's the use of a lock if it has many intelligent functions, but it can't guarantee security, which goes against the original intention of the lock?

I once read a report that a residential area broke into five houses in a row overnight. These five houses have one thing in common. They are all modern fingerprint locks, but the old lock core is more difficult to open. Therefore, I advise you never to buy a fingerprint lock. If the journey is convenient, but you can ignore safety, then you can buy it, but if your ultimate initial intention is to ensure the safety of your home, then you must not buy it.

The electronic lock is mainly for convenience, and any lock can be opened.
