Hello everyone. I hope someone can help me. I did a search and didn't find anything. My wife came out of work and the car doesn't seem to recognize the key. It doesn't automatically unlock/lock doors nor does it start without the key in the ignition. My wife states the key worked when she left the vehicle in the morning. But in the afternoon, while walking to the car the key wouldn't work. I tried using the spare key & the car doesn't recognize it either. Any assistance is greatly appreciated.
