You do have a resistor pellet in your key, but we need to know, when the car refuses to crank over, whether you're seeing your yellow Security light come on and stay on (even after you release the key). Do you?
If so, the VATS anti-theft system is triggering, possibly because your key is dirty or worn and it'* not making a proper electrical contact through that little resistor pellet when you put the key in the ignition.
If not, and everything looks normal otherwise on your dash, then it sounds like you may have dirty, loose or corroded battery cables, or a starter solenoid that'* on its way out. I'd start by removing the battery cables and thoroughly cleaning the terminals (including prying the battery terminal bolts out of the cable ends, and cleaning the contact rings underneath).
