V35,
got your email. will reply in the morning.
in regard to keys - you got lucky. in regard to immobiliser - you paid for something you probably didnt get. they are SUPPOSED to have one fitted by the RAW that complies it. as that car TECHINCALLY sits it is uncomplied. there is a bit of paper floating around the traps that says that the murano shares the same NATS system as the V35 . DOTARS say otherwise.
the OEM NATS 5 system is intact. its not something that can me switched off and removed. it is part of the cars computer.
I'm in/out tomorrow but accessible on the phone - give me call and I will explain.
