My 2004 Volvo XC90 refused to start tonite, occasionally displaying the message "Immobilizer - See Manual".
I searched for solutions, and came across two suggestions: lock & unlock the door 5 times (didn't work) and try turn one the key to position 2, press & hold the odometer button while turning the key to position 3, then release the button & turn the key off. That didn't work either.
I also tried reversing the key, and using the 2nd key - nothing helped.
Any other way to get the car to start?
