My car is at a Nissan dealership and they can't get the ECM or BCM to program to my keys. They can get a BCM replacement, but the ECM is nowhere to be found. From what I can gather, the number under the bar code has to match except the last few numbers. The code on my 08 Sentra SE-R spec V is MEC110-050 C2. Does anyone have one for sale or know where to send mine for repair? Thanks for any leads or tips!
