That's right , after 1995 the key has a chip along with a transponder in the switch that tells the computer to go ahead and allow the car to run . Now it all has to be programmed at the dealer more than likely . Where you should have gone in the first place , this is why you can't hot wire a car despite what you see in the movies , without the chip it ain't gonna run . Kinda makes all those car alarms unnecessary . No one wants to steal your crappy car anyways .
