Which one do you think is logical help

Friends first hello everyone
if i have to introduce myself
Mehmet Birlik
I am 28 years old
I am a notebook specialist
I got a peugeot like you in August.
however, I have not used my car since I had a summer tire due to winter conditions for about 10 days and since I have low road and self-confidence and as a result, the car did not start.
I researched a little and the common opinion was that the battery was dead body bought a new battery bosch brand maintenance-free
I brought a master and had it installed. While the vehicle did not start, the starter started but it did not work.
The imobilizer flashes, the doors do not lock without stopping, only the driver's door is active, the windows are not working.
the master said that we should shock the vehicle's brain and I had the vehicle master
when I called today he said that the insurance table had to change completely

As for my questions and concerns;
can we find the panel not found today and how much does it cost
or is the problem caused by something else?

First of all, look at the alternator and the connector of the vehicle, alternator coals or diodes in the connector may be gone.

Well, I don't understand much, we gave it to a master and he said I'm looking for an insurance table, but they couldn't find it. I am looking for help from here.

No matter how bad the alternator is, the vehicle will run, even if it is not fitted! If the fuse table is likely to be broken, there may be a reverse connection of the pole when installing the battery from the master. Another reason may be an imbalance in the electrical current if the battery of the vehicle is completely dead and if you write the engine volume and you want the fuse tray inside the vehicle if you write the engine inside the vehicle and I will help you with the part.
