2000 Nissan Frontier Remote control, electrical

I have Galaxy 2000RS Remote Start And Keyless Entry Brain in my Nissan frontier, I took off the battery several time to use it in my other car, Last time I install the battery, turned the ignition key, no power at all in the dash board, no door unlock or lock, no radio, nothing except the AIR BAG LIGHT, now it might be this brain, therefore, I will offer $10 if it works, I will be lucky, if not, I would never return it.
