Bought new Used 97 M3 - Keys arent matching.
So I purchased an 1997 M3 Sedan over the weekend. And the door keys, ignition, and the Trunk release key doesnt match.
What is the best way handle this? Can I just go to my dealership the original key my VIN is assigned to and Tumbler/cylinder?
If i swap out the ignition cylinder/tumber, does it affect the EWS? Does anything need to be reprogramed?
