Is your 2020 Subaru Forester key fob acting up? Are you experiencing intermittent lock/unlock issues or finding your vehicle completely unresponsive to the fob’s commands? Before you resign yourself to expensive dealership visits, the culprit could be something as simple as a dead key fob battery. This comprehensive guide is here to walk you through diagnosing and replacing the battery in your 2020 Subaru Forester key fob.
Understanding Your Key Fob
Your key fob is a marvel of miniaturized technology, transmitting radio signals to your Subaru Forester to control a variety of functions including locking/unlocking doors, activating the panic alarm, and even remotely starting the engine. This compact device is powered by a small but mighty battery that wears down over time.
Signs You Need a New 2020 Subaru Forester Key Fob Battery
Knowing when your key fob battery needs replacing can save you time, frustration, and a potential lockout situation. Here are some telltale signs:
- Decreased Range: Do you find yourself needing to be unusually close to your Forester for the key fob to register? This shortened range often indicates a weakening battery.
- Intermittent Functionality: If your Subaru only responds to the key fob sporadically, the battery is likely nearing the end of its life.
- No Response: The most obvious sign – a completely unresponsive key fob usually means the battery is completely drained.
- Dashboard Warning: Some Subaru Foresters might display a dashboard warning message indicating a low key fob battery.

Still Having Trouble?
If you’ve replaced the battery and are still experiencing issues, the problem might be more complex than a simple battery replacement.
“In some cases, a malfunctioning key fob might require reprogramming or could indicate a deeper issue with the vehicle’s immobilizer system. When in doubt, it’s best to consult a qualified Subaru technician,” advises Jake Miller, a seasoned automotive electrician with over 15 years of experience specializing in Subaru vehicles.
