If your Subaru key battery dies, don't worry, you can still start your car. Most Subaru models have a built-in fallback method to start the car. First, remove the mechanical key hidden inside the key fob. Then, use it to unlock your car's door. For push-button start models, hold the key fob flat against the start button and press to start the car. This method uses a backup RFID chip in the key fob to communicate with the car, allowing you to drive to a place where you can replace the battery.
