A key fob, or remote control, is basically your car’s digital sidekick. It houses the electronic brains that allow you to unlock, lock, start, and even adjust some of your RAV4’s settings without fiddling with physical keys.
But this little gadget relies on a battery for its magic. These batteries provide power to the circuitry inside the fob, enabling it to connect with your car’s electronics and perform all those essential tasks.
