Why Your Key Fob Battery Dies
Before we dive into the replacement process, let’s understand why key fob batteries lose their charge. Key fobs constantly emit radio signals to communicate with your car, and this requires power. Over time, the battery’s capacity to hold a charge diminishes, leading to the dreaded “dead fob” scenario.
What You’ll Need
Before you start, gather the following:
- A new CR2032 battery: This is the standard battery used in most Subaru Forester key fobs. You can find these at most electronics stores, grocery stores, or online retailers.
- Small flat-head screwdriver: This will be used to pry open the key fob.
- Optional: Tweezers: These can be helpful for removing the old battery.
Step-by-Step Guide to Changing the Key Fob Battery
Now, let’s walk through the steps to replace the battery in your Subaru Forester key fob:
1. Locate the Battery Compartment: Most Subaru Forester key fobs have a small seam or a small button on the back. You may need to use your fingernail to gently pry open the compartment.
2. Remove the Old Battery: Inside the compartment, you’ll find the old CR2032 battery. Carefully remove it, paying attention to the positive (+) and negative (-) sides.
3. Insert the New Battery: Insert the new CR2032 battery, ensuring the positive (+) side faces up. The battery should fit snugly into the compartment.
4. Close the Battery Compartment: Gently press the battery compartment closed. You should hear a click or feel a slight resistance when it’s securely closed.
5. Test the Key Fob: Try pressing the unlock button on your key fob. If the key fob works, you’ve successfully replaced the battery.
