On my 03 350z I burnt out my bcm by rushing around n jump starting my car with positive and negative crossed. Yes it was the dumbest mistake i have made in a long time lol. After i crossed the terminals my fob stopped working and over night it would drain my battery. I sent out my bcm to be repaired. they called me n told me I completely killed it n i need a new one. told me they will clone my old bcm to a new one. pretty much when I install it, it will be plug and play. $700 n a week later i received it in the mail and installed it. everything works on it but my FOB. I just cant program the fob to the car. Did the programming by pulling the key in and out the ignition 6 times and the hazards flash, turn the key to on position, hit the lock button on the fob n i get nothing. Think i tried like 15 times. my fob worked fine up untill i fried the BCM. thinking maybe i fried something else. i checked every single fuse in the car n there all good. is there something i may be missing?
