With my wife's Prius, my key doesn't work any more, wirelessly. I thought that putting the key into the slot would possibly recharge a battery in the key, but even after very long trips, the key will not unlock the car if it's in my pocket. I can only unlock or lock the doors by removing the actual key in the fob. And then I can only start the car with the key fob in the dash holder. I assume there has to be a battery in there, so is it replaceable by the dealer?
