sir,
i have second hand opel omega, the battery gets dead because of not using it. after i replace the battery, the check engine blinks. i look to the owner's manual and i found out that if the check engine blinks, there is aproblem in immobiliser. i went to the shop and i ask them to diagnose my car with their scanner. they found out that it has a problem with the key immoiliser. they check the key and they found out that the has no trasponder inside. how can i start my car without this transponder? please help. thank you very much.
