I know this is a maxima forum but its a similer car at my shop a 08 infinity g35. it has no power to anything. we put a brand new battery in both the smart key and the vehicle, still when we push the button no dash lights no radio nothing happanes. on the button it has the words lock, acc and on, the work lock just stays on. I have power to my curtosey lights and I can adjust the seat and lock and unlock witht he fob, but when ya press the button to fire the motor its like im not even pressing the button

anybody have any ideas
