Finding the right battery for your Subaru Forester key fob can be a surprisingly tricky task. With different Forester models and key fob styles, it’s crucial to know exactly what you’re looking for to avoid frustration and wasted time. This article will provide a comprehensive guide to help you identify the correct battery, replace it, and offer troubleshooting tips for common key fob issues.
Identifying Your Subaru Forester Key Fob and its Battery
The first step in replacing your Subaru Forester key fob battery is identifying the correct type. Different Forester models and years use different key fobs, which require different batteries. Generally, Subaru Foresters use CR2025 or CR2032 batteries. The owner’s manual is the best resource for this information. You can also find the battery type stamped on the existing battery inside the key fob.
How to Open Your Subaru Forester Key Fob
Opening your Subaru Forester key fob can be slightly different depending on the year and model. Some fobs have a small release button or slot. Others may require a small flathead screwdriver to gently pry open the casing. Be careful not to damage the internal components. Once open, you can easily access the battery.
What Battery Does a Subaru Forester Key Fob Use?
While CR2025 and CR2032 are the most common, double-checking your owner’s manual or the existing battery is always the best practice. These batteries are readily available at most electronics stores, pharmacies, and online retailers.
CR2025 vs CR2032: What’s the Difference?
Both CR2025 and CR2032 batteries are 3-volt lithium coin cell batteries. The key difference lies in their thickness. The CR2032 is slightly thicker than the CR2025. While they may seem interchangeable, using the incorrect battery can cause problems with the key fob’s fit and functionality. Always use the specified battery for your specific Subaru Forester model.
Replacing the Battery in Your Subaru Forester Key Fob
Once you have the correct battery, replacing it is a simple process. Carefully remove the old battery, noting its orientation. Insert the new battery, ensuring it matches the polarity of the old one. Close the key fob casing securely.
Testing Your Key Fob After Battery Replacement
After replacing the battery, test all the key fob functions, including locking and unlocking the doors, panic button, and remote start (if equipped). If the key fob is not functioning correctly, double-check the battery installation and ensure the battery is fresh.
Troubleshooting Common Subaru Forester Key Fob Issues
Sometimes, even after replacing the battery, the key fob may not work. This could be due to several reasons, such as a faulty key fob, programming issues, or problems with the car’s receiver.
