Hello,
Sorry for posting on this post instead a new one, but I think someone can help me with my central locking problem.
After put 2 CR2025 New batteries on the fob, the intermittent lights blink when a key is pressed, but nothing happens.
There was no fuse, so put a 20A yellow fuse and testes again, still not working... The central locking seems dead.

By the way, the passenger Door and trunk does not locks/unlocks by the key, I have to manually open/close the passenger door.
What should I check?
There are two different modules related to the locking, a Delphi unit and the vacuum pump with 3 outputs.
If I got an used unit (Delphi or Vacuum pump?) Will I need pair it with a computer?
What should I replace first? Vacuum pump or electronic next to the pump?
Thank you!
