Occasionally, when I start the car, the horn beeps once, the bright lights come on, the fog lamps come on, and the windshield wipers and turn signals don’t work. The display reads “programming active”. Also, twice in the past, I have had to have the vehicle towed to the dealer because of a “damaged key”. Once it happened while I was actually driving\ the car. It stalled when I was waiting for a traffic light, and the “damaged key”message came on and I had to have it towed in!
