I'm not sure if an authorized dealer would do that, it's a safety feature and removing any of those would make the vehicle less legal and less safe and that would be a liability if something happens that can be traced to the dealer decoding the car. I could be wrong but in the US where everyone can sue anyone for anything, I am not sure a dealership would take that chance. I read that if you change the coding and bring the car for service, BMW pretty much resets it anyways.
