Keys: The Full Story.

Apologies for reviving a dead thread, but I wanted to just confirm something. I assume the issues in this thread are relevant for other models.

I'm trying to help someone with a '99 e46 328i that had its EWS module replaced because the original suffered for some sort of liquid damage. So they got a new EWS, but obviously the car won't crank. My diagnostic set up can't even recognize the car, which I assume is due to the OBDII to 20 pin adapter I needed, and now have (I hope).

However, after reading this thread, I have learned that they need completely new keys as well; is that correct? Everything else, I should be able to do myself? Do I need the new keys to be able to perform the EWS to DME realignment?

I'm surprised the dealer sold the part without coding it to the vin and without telling them they have to get new keys for it to work.

Thanks in advance for any input.
