QX4 ECM question

[ceh37205]

My ECM was fried when the idle control valve malfunctioned. I found a used ECM appropriate for it's manufactured date and after connecting it, the vehicle will not start. Do I need to re-program the key? Any help is appreciated.

Does the truck crank and just not fire or doesn't it do anything with your key? If it cranks but will not fire it is most likely a code mismatch as you stated between the key and the new ECM?

It cranks but does not fire. I'm taking it to the dealer to have them regester the key with the ECM and dump all older keys. Hopefully that wll work. Do you know any other way to accomplish this other than the dealer route?Thanks.
