Goodmorning to everyone,
my father has a Fiat Punto first series (176) 75 ELX since 1997. A strange thing happened, on Monday we changed the battery (usually the duration is 5 years) so this is the fifth that we change only that after changing it the key code light is fixed on and engine not turn on. We tried with all three keys including emergency starting, but the injector light does not come on. I tried to measure the impedance of the immobilizer antenna and 33.35 ohm.
The problem may be the antenna or i must to change 46734570 electronic control unit?
If i buy a new electronic control unit i need to code the old keys?
Thanks
