hey how are you

you will need a Nissan scanner or equivalent to program the key .unless key is bad and not sending RF signal

if you are replacing the with another ECU from another car , The ECU ,BCM and Key have to come out from same car for it to work .

if you dont have all matching parts , then Nissan scanner is the only way to do it

Please let me know if that works for you

Thank You
