Electrical not working

Hi, I parked my car at my home. When I next tried to start it the car would not open with the key button. I had to use the manual key to open the door, Next when I put the infra red key fob in the ignition nothing happened. I had no dashboard lights and no ignition.

Because the car is an automatic. It is stuck in Park. The cars battery and key battery's have been checked I have also tried a booster pack on the car battery, but still nothing.

I have checked all the fuses in the three compartments on the car they all look okay.
Do you have any idea what could be causing this problem or could you give me an idea of the relays in the fuse-box? I have looked online but keep getting different answers.

This is where I found your webpage.

Thank you
