I have an Alfa 155 Twinspark Silverstone, reg in 1997. I have a constant problem with the immobilizer/code system, which was never a problem for the first 5 years or so, but now seems to kick in after a battery change or flat battery. The code light flashes or stays on. The engine won't start no matter what. I remember once the selling dealer explained something about this but that was many years ago and now I haven't a clue. The "special key" I was given was stolen in a robbery years ago. How can I get the car to start? Any ideas?
