2007 g37 S wont crank

I feel like this is a common issue but i need to get this car fixed and I just need the straightforward fix. I bought a cheap emulator from m4key and it didnt work, just triggered the anti theft. The key works properly, and the car can go to on start and acc mode but it wont start cranking. I didnt hear a click when trying to start it and it doesnt seem to have any eletrical issues. What should I do to get this car working asap? I just need it running so i can get it sold.
