hey, got another problem with my vectra b sri, after my battery went flat i put a brand new one in but my immobiliser light is flashing on my dashboard. i phoned a vauxhall garage up and they said i need to pay 20 quid for a carpass which will have a code to reprogramme my immobiliser but will take between 3-5 days to arrive. is there a cheat that i can do to sort this or is the carpass the only way to go?
cheers.
