My immobiliser won't go off. It's been to the main vauxhall dealer who say they can't fix it because they don;t have the old tech 1 tool, but when I managed to find somebody with one he says it won;t fix it. Do I have no option but to scrap it just because I can't get one tiny wee red light to go out. It is pretty old but still in good condition so i'm loathe to get rid. The key (transponder) has been checked and is working OK.
