The wifes Meriva wont start (or turn over) and the immobiliser fault symbol (flashing orange lock) is showing. I dont have a pin code for the car (now realise I should have got it at time of purchase). I have changed the car remote battery - no success, we only have one key, I have also left the symbol flashing for over 20 mins as told on utube but it did not go out. I was going to disconnect and reconnect the battery but before I did I rang a mobile locksmith who told me not to. He said if I have not got the passcode/pincode I must go to Vauxhall and get the correct pin and will cost about £35. Once I have got that he will I think come along and sort it out via the ecu? and it will cost me £65 assuming its straight forward. If anyone has any suggestions I would appreciate it. To be honest if the locksmith does the job and it works it doesnt sound dear but just checking for alternatives..
