They mentioned something about needing to have all our keys so they could reprogram them when the ECM arrives. If they have to reprogram everything anyway, why does the serial number matter? Couldn't they take the ECM from another CR-V and reprogram the keys to match, remotes, etc? Won't they have to do this anyway when the backordered ECM arrives?
I'm just wondering if it's technically possible, or just a matter of policy. The dealership told me it was technically impossible. But if I find out I had to wait weeks for something that COULD have been fixed in a few hours, I'll be miffed
