sounds like your vats just went bye bye. click the key on and the car does nothing? to replace the cylanoid the vats reads when u turn your key costs about 100-120 bucks. or u can do like i did and take the damn thing off and run the chip in your key to the wire so u can be like to hell with it. down side is now your car can be hot wired and stolen but a good alarm can take care of that
