How to lock the door?

1, indoor anti-lock braking: There are many methods for indoor anti-lock, depending on the type of lock. Some locks can be pressed once, some turn the handle once, and some turn it twice with the key.

This kind of indoor lock is mainly to give the owner a private space. After the lock is locked, people outside can't enter the door even if they have the key, so they have to knock on the door to let people inside open the door.

2, outdoor anti-lock: generally, the key is turned twice, even if people in the room have a key, they can't open it, so they can only use the key to open it outdoors.

This can prevent thieves from entering the house through the window, stealing things and leaving directly from the gate.

The concept of anti-lock braking: Anti-lock braking is a Chinese character, and the pinyin is f m 4 n su ǒ. It means to lock the door outdoors and not to open it from indoors. The door is locked indoors and cannot be opened from the outside.

Extended data opening method:

1. When we accidentally locked the door and didn't bring the key out, we can take out a hard card (such as supermarket membership card, fitness card, beauty card, etc. ).

We carefully insert the card into the door and move it gently, because the door is only locked once, and the first lock has good elasticity. When the hard card moves up and down, it is easy to insert into the gap of the first lock. Using this gap, the locked door will naturally open.

If you have a key, please ask someone to open it from the outside.

3. Some door locks can be removed from the inside, and the door will be opened. Then reset and install the internal components.
