MERSEDES ECU, EIS, ELS SWAP OUT

This is going to be a nightmare. Some of the parts are tied to the original VIN and can't be changed at the dealer, only a factory programmed part will work properly (unless you can have someone try to hack it... not likely to work) Keys are almost as bad, there will have to be a lot of ownership proof to get replacement ones coded properly to the VIN and EIS Most of the answers will be "can't do it that way" or very $$$$$ replacement parts.

Thanks for your reply i have my original ecu . can i just swap imobiliser chip. And be good . ?
