Power Up Your Subaru: How to Change Your Key Fob Battery Like a Pro

Your Subaru key fob is your trusty companion, granting you access to your beloved vehicle. But just like any other gadget, it relies on a battery to function. When that battery starts to die, you’ll notice your fob’s range decreasing, and eventually, it might not work at all.

Don’t panic! Replacing a Subaru key fob battery is a simple task that can be done in just a few minutes. This guide will walk you through the process, step-by-step, ensuring you can get back to enjoying the convenience of your key fob in no time.

Identifying Your Subaru Key Fob Type

Before diving into the battery replacement process, it’s essential to know which type of Subaru key fob you have. There are generally two main types:

1. Traditional Key Fob: This type features a separate key blade that can be manually inserted into the ignition. The fob itself is typically rectangular or oval-shaped, with buttons for locking, unlocking, and possibly trunk release.

2. Smart Key Fob: This type integrates the key blade into the fob itself, making it sleeker and more compact. It also offers keyless entry and push-button start functionality.

Knowing your key fob type will help you locate the battery compartment and understand the specific steps involved in replacing the battery.

Gathering Your Supplies

Before you start, ensure you have the following items:

• New CR2032 Battery: This is the standard battery used in most Subaru key fobs. You can find them at most electronics stores, auto parts stores, or online retailers.
• Small Screwdriver: You might need a small, flat-head screwdriver to pry open the battery compartment.
• Optional: Tweezers: These can be helpful for removing the old battery.

Replacing the Battery in a Traditional Key Fob

1. Locate the Battery Compartment: Examine your key fob closely. You’ll usually find a small seam or a release button on the back or side of the fob.

2. Open the Compartment: Gently pry open the compartment using your screwdriver. If there’s a release button, press it to open the compartment.

3. Remove the Old Battery: The old battery will be visible. Use your fingers or tweezers to carefully remove it.

4. Insert the New Battery: Align the new CR2032 battery with the positive (+) and negative (-) terminals inside the compartment.

5. Close the Compartment: Carefully snap the battery compartment closed.

Replacing the Battery in a Smart Key Fob

1. Locate the Battery Compartment: On most smart key fobs, the battery compartment is located on the back side, usually hidden under a small cover.

2. Remove the Cover: Gently pry open the cover using your fingers or a small screwdriver.

3. Remove the Old Battery: The old battery will be visible. Use your fingers or tweezers to carefully remove it.

4. Insert the New Battery: Align the new CR2032 battery with the positive (+) and negative (-) terminals inside the compartment.

5. Replace the Cover: Carefully snap the cover back into place.

Testing Your Key Fob

Once you’ve replaced the battery, it’s essential to test your key fob to ensure it’s working correctly. Try locking, unlocking, and opening the trunk (if applicable) to confirm that the fob is responding.

Tips for Extending Battery Life

Here are some tips to help your Subaru key fob battery last longer:

• Avoid Extreme Temperatures: Heat and cold can significantly impact battery life. Keep your key fob away from direct sunlight and extreme temperatures.
• Store It Properly: When not in use, store your key fob in a cool, dry place.
• Minimize Button Pressings: Avoid unnecessary button presses, as this can drain the battery.
• Consider a Battery Case: Investing in a battery case can provide extra protection and help prevent accidental damage.

When to Replace the Battery

While a typical CR2032 battery can last for several years, there are signs that indicate it’s time for a replacement:

• Decreased Range: If your key fob’s range is significantly reduced, it’s a strong indication that the battery is low.
• Intermittent Functionality: If your key fob works sometimes but not others, it’s likely a sign of a failing battery.
• No Response: If your key fob is completely unresponsive, the battery is definitely dead.
