Central Lock System

I have a 2002 Model 206XR car. When I bought the car, there was another lock apart from the central lock. I don't care to hang out afterwards, but these days I started to be annoyed.

I press the button on the original key of the car, the doors open automatically, but it closes instantly, so there is no time to open the door . Then I unlock it normally, no problem.

And the interior lamp of the car does not light up with the door open

also it flashes in a position, I guess it has something to do with the door

once I showed it to the electrician, he said a lot.

Note: If it does not cause any problems, I opened the subject to the Ask Master section.
