Battery went flat at christmas and jumped started it, then it died and wont start. Box with wavey line on dash flashing, so put it on a diagnostic computer and it registers no immobiliser fault, tried to re-program keys and the immobiliser has completely locked the system out so that not even the 4 digit pin from Renault can bypass. Now tried Remotekey.co.uk who have been incredibly helpful but their bypass gadet has made no difference, anybody any idea, totally totally arsed off Renault owner!!!
