'07 Will Not Start Unless Ignition Key is Wiggled

Sounds corny but that is what is happening with my wife's durango. The car however will start but cannot be put into gear. We noticed the radio will not turn on, windows will not open, fan will not turn on. I tried a different key and the same results. However if I shake the key the instrument panel goes to normal and all is well. This happens on both keys. It sounds like the anti-theft is not detecting the resistor chip. What do you think. By the way, noobie here.
