Hello, everyone!
I hope you're all doing well. I find myself facing a challenge with my car's central locking system, and despite checking the usual problem points, I'm reaching out to you for some guidance.

This is what I've checked so far and nothing seems to give a hint:
Checked all the fuses in the glove box (11, 27) and 59 in the trunk.
Diversity antenna is in good condition. No oxidation or burnt.
The car locks and unlocks from the button inside the car.
The radio is functioning properly.
Key battery has been verified and is in good condition.

If this helps, the key unlock range was getting shorter everytime until it stopped working. Also the mirror electronic adjustment stopped working. Folding works.
After all this I think of removing the front driver's door panel and check the wiring.
If anyone has faced the same problem I will be greatful for some tips.

Thank you in advance!
