ANSWER: ok well first off try a different key, your might have the theft controller in the key , the bcm is usually what controlls the theft system  (body controll module) if so equipt. if the theft light is on  tyr this ... put your key in the ignition turn it to on and leave it on for fifteen minutes then try to start and see if it will reread the key, of coarse check all fuses first , you may have 2 fuse locations , check ownbers manual for them,
