Unlock the Secret: How to Change Key Fob Battery Subaru Forester – DIY Guide

It’s a familiar scenario: you reach for your Subaru Forester key fob, press the unlock button, and… nothing. The dreaded dead battery. Don’t worry, changing the battery in your Subaru Forester key fob is a simple and straightforward process that can be done in just a few minutes. This guide will walk you through the steps, making it easy for you to regain control of your car.

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.

Troubleshooting Tips

If your key fob still doesn’t work after replacing the battery, here are some troubleshooting tips:

• Check the battery’s orientation: Ensure the new battery is installed with the positive (+) side facing up.
• Clean the battery contacts: Use a soft cloth to wipe away any dirt or debris from the battery contacts and the key fob’s battery compartment.
• Try re-synchronizing the key fob: Some Subaru Forester models require you to re-synchronize the key fob after replacing the battery. Refer to your owner’s manual for specific instructions.
• Contact your Subaru dealership: If none of these tips work, it’s best to contact your local Subaru dealership for assistance.

Maintaining Your Key Fob’s Battery Life

Here are some tips to help extend the life of your Subaru Forester key fob battery:

• Avoid extreme temperatures: Exposure to extreme heat or cold can shorten the battery’s lifespan. Store your key fob in a cool, dry place.
• Minimize unnecessary button presses: Only use the key fob buttons when necessary. Constantly pressing buttons can drain the battery faster.
• Replace the battery regularly: Even if your key fob still works, it’s a good idea to replace the battery every 1-2 years to ensure optimal performance.

The End of the Road for Your Old Key Fob Battery: Recycling and Disposal

Once your old battery is no longer useful, it’s important to dispose of it properly. CR2032 batteries contain mercury, which can be harmful to the environment if not disposed of correctly.

• Check with your local recycling center: Many recycling centers accept batteries for proper disposal.
• Look for battery collection programs: Some retailers and electronics stores have battery collection programs.
