Ok, I understand
Thanks all for your answer, probably I'll buy new original Fiat key....even if it's very very expensive...

Hello, I have a Fiat Grande Punto 1.3mjt, year 2006, that don't recongnize my original remote control The remote control does not work by 15 days...I tried to change remote battery but nothing to do... Do you know if Multiecuscan, on version 2.1, can reprogramming remote control like on Fiat Stilo? ...
