That may be true for this particular locksmith but if they have the scan tool capable of doing it then they can do it. Not many locksmiths that I am aware of can program ECMs if they are replaced. However, the idea that only the dealer can do it is not accurate.
Most of the locksmiths that I have run into have key programmers but if the ECM is replaced, they may not have the scan tool that can do that.
Also, used ECMs on these newer vehicles will not work as they are VIN specific. So, once they are programmed to a vehicle, they will only work on that vehicle.
Plus, the vehicles that can take a used ECM, they do not require programming as they are already programmed to the other vehicle.
There may be some info that is getting lost from what he meant but based on what you told me, it sounds like he may not be completely informed.
