Hey, friend They! Recently I saw an interesting news: At three o\’clock in the morning, a female owner in a small area was scared and sweated in a cold sweat by her own smart lock – the lock actually opened itself! This reminds me of the chat with a locker chef two days ago. He said that more and more people are changing back to mechanical locks, which made me fall into deep thought: Is it really not possible for smart locks, or are we using the wrong method?

People who buy smart locks are crying

Seriously, when I first bought smart locks, I thought about \”I didn\’t have to do it.\” The key is that life is so beautiful.\” What\’s the result? The \”smart\” locks bought back at a big price are simply a trick!

Finger mark identification? Haha, it’s awkward to have a little water on your fingers on rainy days! My friend @Guangdong Caicai encountered this: I was throwing garbage in the floor at night, but when I came back, I couldn’t get into the door. Transfer password? It\’s not possible to lock it! Reversal trial? Sorry, it\’s locked! This time, I stood at the door in the middle of the night like a fool.

Human facial recognition is even more absolute, the funny thing I have seen is @It will be a good encounter if you don’t want things. The old lady compared the doors for a long time every day, but the doors just didn\’t open. Finally, I still found a locker and spent 650 oceans to change the new lock. Is this smart lock afraid it’s not a genius, and is it a special choice for the elderly to bully them?

Do you think this is the end? Take a look at these \”magical operations\”

1. 1. Origin automatically? Damn it!
   It\’s right, it means literal. Some smart locks will open themselves inexplicably, which is even more scary than ghost stories. Electronic parts aging? Is circuit protection good? What if it doesn’t matter, it’s just not reliable anyway!
2. 2. The function is too \”intellectually retarded\”
   What are you going to stay and take a snapshot, straightforward It\’s just a joke. The thief is not stupid, can you just cover up the situation? @Tong Dongqi\’s experience is even more funny: people come and go in the building, and the doors shout \”No faces have been detected\” every day, which makes the neighbors want to call the police.
3. 3. The price is so beautiful that it makes people feel heartbroken
   A lock is moving Thousands, the price is almost half of the door! Not to mention the subsequent battery fees and repair fees, it is simply a bottomless pit.

Insiders\’ advice: Teach you not to get into pitfalls

As a person who has been \”harmed\” by smart locks, I must tell you:

Don\’t buy fully automatic!
Why? Fully automatic is like a willful child. This is not good today, but that is not right tomorrow. Semi-automatic at least retains the mechanical structure, at least it won\’t lock you out of the door.

C-level locking core is the bottom line!
Don’t be smart, it’s nonsense if you can’t do a lock core. It took 270 minutes for the C-level lock to open the lock, and the thief would give up the lock when he saw it.

The less functions, the better
Finger marks, passwords, and mechanical keys, these three are used! Other fancy and whistle functions are routines that will make you spend more money.

Last saying

@Zazhahua said correctly: After using the smart lock for three years, he still changed back to the mechanical lock. Why? Because the dead person is different from the face, he closed the door and didn\’t let him look back. I turned around and opened, isn\’t this intentional trouble?

Seriously, smart locks are really suitable for some people, but they are definitely not the best choice for everyone. To me, spend a lot of money It is better to buy a \”smart\” lock for money than to use mechanical locks in practice, so you can sleep peacefully by calculating it!

Yes, there is also an Easter egg for friends who are feeding cats: You want When the cat door is opened, use a trapezoidal storage box, which is fixed to the door with a hot melt and nanometer double-sided rubber. This trick works, at least more reliable than some smart locks!
