Why Does My 2021 Subaru Key Fob Need a New Battery?

Key fobs rely on small batteries to transmit signals to your car. Over time, these batteries drain, leading to decreased range and eventually, a non-functional key fob. Recognizing the signs of a dying battery can save you from being stranded.

• Reduced Range: Do you find yourself having to be closer to your car to lock or unlock it? This is a primary indicator of a low battery.
• Intermittent Function: Does your key fob sometimes work and sometimes not? This inconsistency points towards a battery on its last legs.
• No Response: If your key fob is completely unresponsive, the battery is likely dead.

How to Replace the Battery in a 2021 Subaru Key Fob

Replacing the battery in your 2021 Subaru key fob is straightforward and typically only requires a few common tools. Here’s a detailed, step-by-step guide:

1. Identify Your Key Fob Type: Different Subaru models may have slightly different key fob designs. Consult your owner’s manual or a quick online search to ensure you have the correct instructions.
2. Gather Your Tools: You’ll typically need a small flat-head screwdriver or a similar tool to pry open the key fob casing. A CR2032 battery is the standard replacement for most Subaru key fobs.
3. Locate the Release Button: Most Subaru key fobs have a small release button or switch on the back. Press this button and gently separate the key fob halves.
4. Remove the Old Battery: Carefully remove the old CR2032 battery from its compartment. Avoid using excessive force, which could damage the key fob.
5. Install the New Battery: Insert the new CR2032 battery, ensuring the positive (+) side faces upward, just like the old battery.
6. Reassemble the Key Fob: Align the two halves of the key fob and press them together until they snap shut.
7. Test the Key Fob: Try locking and unlocking your car to ensure the new battery is working correctly.

Common Issues and Troubleshooting

While the process is typically simple, here are some common issues and their solutions:

• Key Fob Still Not Working After Battery Replacement: If the key fob remains unresponsive, double-check that the new battery is correctly installed and that it’s not a defective battery. subaru key fob battery replacement 2021
