Why Does the Subaru Forester Key Fob Battery Need to Be Replaced?
The key fob battery in your Subaru Forester is essential for the remote entry system and push-button start functionality. Over time, the battery can lose its charge, leading to problems like the inability to unlock your doors remotely or start your vehicle. It’s important to recognize the signs of a weak battery early to avoid being locked out of your car or facing other inconveniences.
How to Replace Your Subaru Forester Key Fob Battery
Replacing the key fob battery in your Subaru Forester is a relatively simple process that can be done at home with just a few tools. Follow these steps to replace the battery and restore your key fob’s functionality.
Step 1: Gather Your Tools
Before you start the replacement process, make sure you have the following items:
- A flathead screwdriver or a plastic prying tool
- A replacement battery (typically CR2032 coin cell battery)
- A clean workspace
Step 2: Open the Key Fob
The first step in the replacement process is to open the key fob. Depending on the model year, the key fob may have a small seam along the edge. Use a flathead screwdriver or a plastic prying tool to gently separate the two halves of the key fob. Be cautious not to damage the plastic casing while opening it.
Step 3: Remove the Old Battery
Once you’ve opened the key fob, you’ll see the old battery inside. Carefully remove the old battery from its compartment. You may need to use a small flathead screwdriver to gently lift the battery out. Be careful not to damage any of the internal components while doing so.
Step 4: Insert the New Battery
Next, take the new CR2032 coin cell battery and place it into the compartment, ensuring the positive (+) side is facing up. The battery should fit snugly in the compartment. If the battery is not sitting correctly, double-check the orientation and ensure there’s no debris preventing it from sitting properly.
Step 5: Reassemble the Key Fob
After inserting the new battery, it’s time to put the key fob back together. Gently snap the two halves of the fob back together, ensuring they fit securely. Make sure that the buttons are functioning and that the fob is closed tightly to prevent any loose parts inside.
Step 6: Test the Key Fob
Once the fob is reassembled, test it by pressing the buttons to check if the remote entry and start functions are working properly. If the key fob is still not working, try re-opening it and ensuring the battery is correctly seated.
Troubleshooting Tips for Subaru Forester Key Fob Battery Issues
If you’ve replaced the battery but the key fob still isn’t working, there are a few things you can check:
- Check the Battery Orientation: If the new battery isn’t inserted correctly, the fob may not work. Ensure the positive (+) side of the battery is facing up.
- Inspect for Corrosion: Over time, the battery terminals may corrode. Clean any corrosion gently with a cotton swab dipped in rubbing alcohol.
- Reprogramming: In some cases, the key fob may need to be reprogrammed after a battery replacement. Consult your vehicle’s owner manual for instructions on how to do this or visit a professional.
When to Seek Professional Help
While replacing the battery in your Subaru Forester key fob is typically an easy task, there are some instances when it’s best to seek professional assistance.

In such cases, it’s recommended to visit a Subaru dealership or a trusted auto locksmith for further diagnosis and repair.
