So, what is the main problem facing the intelligent door lock? There are loopholes in security. We have seen on the news that even a luxury car with a wireless door lock may be cracked by hackers.

But obviously, even if it is not a smart door lock, thieves may easily pry open your door through tools. Therefore, we don't have to worry too much about the safety of smart door locks, after all, most ordinary people won't get the favor of hackers' Unless there is a serious universal loophole in an intelligent door lock, this situation has not yet occurred.

The more critical problem of the intelligent door lock may be its various hidden dangers of instability. For example, once the smart door lock fails, how to open the door ( Although some styles provide traditional keys as a backup solution)? In addition, the door lock is obviously a device with a long life, and people do not need to replace it frequently, but the smart door lock needs to be connected to a mobile phone, but when the mobile phone system is upgraded once a year, you cannot fully guarantee the backward compatibility of the door lock. Of course, you may also encounter some unexpected situations in use, after all, it is not just a simple mechanical structure device. Lock is one of the best inventions of mankind. Only with it can we have privacy. However, it does not seem to have changed much for thousands of years until the intelligent door lock brought by Internet of Things technology'.
