If you are using the smart key and you do not have it in the ignition, it will send a signal thru the car speakers to let you know that the keys are not in the ignition(beep,beep,beep,beep), and that they are to far from the sensor. Next time you are driving and the keys are in your pocket, pull them out and wave them around the speedometer. It will notice keys in car and the beeping will go away.
