Automatic lock issue

Good evening, I have a model 307, I have a problem.

THE SAME QUESTION I have a naughty child in me, we get in the car at home, trying to open the window and the door, I press the klit button from the inside, but I still open the door manually, but I open it in the same way on the glass, but it still opens. I showed the electrician, I asked a few friends, I could not solve it. unfortunately the problem continues

The lock key inside only prevents it from hurt from outside. It does not prevent the door from opening. There is no problem. When you insert the key and turn it, it does not open from the inside again.
