That doesn't sound good, and nobody else has posted any problems like that. Did they give you an estimate on time involved, either in getting the part or doing the work? My Sport died on me twice when stopped, but it was a mixture issue (lean) that was tweaked at the 600 mile service. Did the dealer sound 100% sure that the immobilizer was the problem?
Someone with immobilizer experience will chime in here, I'm sure. BTW, what part of the world are you in?
