philk 0 Report post Posted July 1, 2012 Hi I don't have any issue but I want to know how do you tell if your car has a factory Immobiliser or if you have a transponder key? Sounds like a dumb question I know Any info would be great Cheers Quote Share this post Link to post Share on other sites
Allanw 1071 Report post Posted July 2, 2012 I believe all E39's had the imobiliser/transponder key. Only some had the actual alarm though. Quote Share this post Link to post Share on other sites

Sounds like a dumb question I know Any info would be great Cheers Every E39 has the immobilizer fitted ex factory. It is an integral part of the vehicle and cannot be removed.
