Skoda Fabia II - unlocking the door with the key and central locking

Hello
Unfortunately, after a long search, I could not find anywhere on the forum the answer to the problem that I encountered, namely what could be the reason that when opening the door with the key on the passenger side, it opens all the doors with the trunk, but does not open the driver's door, but when I open it on the driver's side, I have to turn the key to the end, then all the doors open, and when I turn the key, all except the driver gently open, the central locking works the same, that it does not close or open the driver's door, all other doors normally. Where can the problem lie, or maybe someone has already encountered such a problem.
best regards

In the driver's door lock

If the topic is still current, I suggest checking the door lock actuator from the driver. The key has to be turned more to open the lock mechanically because the actuator does not work. There may also be a broken (break) wire supplying the actuator of this door.
