In the US Market, Immobilizer has been around for over 15 years now on VW and Audi. But I'm starting to see cases where the factory scan tools are no longer able to do Immobilizer work on older vehicles. I offer a service in which in which I can retrieve the PIN number from instrument clusters and ECMs that are shipped to me. My fee is a base price of $20 for set up and return shipping, then $20 per PIN retrieved. Contact me for more information. Please be sure to include the VIN of the vehicle you are working with. Thank you.
