Video tutorial

Have we ever wondered how the door lock of a car works? This video shows us. In fact, as the YouTuber rightly points out, if we pull the handle, looking at the mechanism of the door, we see that nothing happens, nothing moves; and this is true whether the operation is carried out from the outside or from the inside.

In reality, what locks the door is the bar located in the door frame: if we do a test with the keychain, we see that inserting the keychain ring inside the lock locks the door.

However, if I release the button, whether from the inside or the outside, the lock opens. That's how it works!
