Recognizing a Dying 2021 Subaru Forester Sport Key Fob Battery

Several signs indicate your key fob battery is nearing its end. Reduced operating range is a common symptom. You might find yourself needing to be much closer to your vehicle for the key fob to function. Another tell-tale sign is a weak or intermittent key fob signal. If you have to press the buttons repeatedly or hold them down longer than usual, it’s likely the battery is dying. Dimming key fob lights are also an indicator. If the LED on your key fob appears fainter than normal or doesn’t light up at all, the battery needs replacement. Finally, completely unresponsive buttons are a clear sign the battery is dead.

Replacing the 2021 Subaru Forester Sport Key Fob Battery: A Step-by-Step Guide

Replacing the battery in your 2021 Subaru Forester Sport key fob is a simple DIY task. First, identify the type of battery required. The 2021 model typically uses a CR2032 battery, which is readily available at most stores. Next, locate the small release button or slot on the key fob. This may require a small flathead screwdriver. Gently press the release and separate the key fob halves. Inside, you’ll see the battery. Carefully remove the old battery and insert the new CR2032, ensuring the positive (+) side faces upwards. Finally, reassemble the key fob halves, making sure they click securely into place.

Sometimes, a new battery doesn’t immediately solve key fob problems. If you’re still experiencing issues after replacing the battery, check the key fob alignment with the vehicle.
