My 2011 Toyota Camry sent me a frightful warning. “The dashboard displayed a warning that the key battery was low. There are two ways to interpret that.” The key may refer to the key fob that starts and unlocks the vehicle. Alternatively, “key” could also imply “important.” Fortunately, the key that unlocks and starts the automobile is what a Toyota refers to when it indicates key battery low. Or the key fob, if your automobile is equipped with one.
I was relieved to hear about one of these and not the car’s battery on my Toyota dashboard.

If the key fob battery is dead, certain manufacturers feature a backup system that enables this approach to function. For instance, many more recent Fords include a pocket in the dashboard or a slot on the steering wheel where you may place the actual key fob to start the car.
