How to Triumphantly Replace a Subaru Key Fob Battery

You’re standing in the chilling breeze, pressing the key fob against your palm, but your Subaru doesn’t chirp back. It’s the battery, dead again.

Don’t worry; you’re about to conquer this task. Armed with a fresh battery and a dash of confidence, you’ll navigate the snug compartments of your key fob with ease.

In minutes, you’ll have replaced the battery and be back to hearing that reassuring beep of your car responding to your touch.

Key Takeaways

  • Identify your key fob model by checking for physical key or sleek design, release button or pry access, number of buttons and their arrangement, and model number on the back of the key fob.
  • Gather necessary tools such as a small flathead screwdriver or plastic pry tool and the correct battery type, and consider disposal methods for the old battery.
  • Access the battery compartment by using a flathead screwdriver or coin to pry open the key fob, being patient and gentle due to the waterproof features, and separating the two halves to reveal the battery compartment.
  • Install the new battery by aligning it with the positive side facing up, gently pressing it down into its compartment, ensuring a snug fit without applying force, and carefully closing up the key fob without forcing it.

Identify Your Key Fob Model

Before you embark on your battery replacement quest, it’s essential to determine which model of Subaru key fob you’re wielding. You’ll find that Subaru has introduced several key fob versions over the years, each with its unique design and battery requirements. Knowing the specific model variations can save you time and ensure you purchase the right battery.

First, take a close look at your key fob. Does it have a physical key that slides out or is it a newer, sleeker version without a visible key? This detail can immediately narrow down the versions you’re dealing with. Some key fobs have a release button for the key, while others might require a gentle pry to access the internal compartment.

Additionally, the number of buttons and their arrangement can hint at the model variations. A three-button key fob could belong to older model Subarus, whereas a four or five-button layout might be part of the newer lineup.

Don’t overlook the back of the key fob; sometimes, there’s a model number etched into the casing. Armed with this information, you’ll be ready to hunt down the perfect replacement battery for your Subaru key fob.

Gather Necessary Tools

Once you’ve identified your key fob model, you’ll typically need a small flathead screwdriver or a plastic pry tool to begin the battery replacement process. These tools help you avoid damaging the fob as you pop it open to access the battery compartment. Remember, the right tools make the job easier and safeguard the integrity of your key fob, which is crucial considering the cost of a replacement.

You’ll also need the new battery itself. The battery type is usually listed in your owner’s manual or on the old battery. Ensure you’re buying the correct one; mismatching batteries can shorten the battery lifespan of your new cell or even damage your key fob.

Once you’ve got your tools and the new battery ready, consider the disposal methods for the old battery. It’s not just trash; batteries contain chemicals that can harm the environment. Many stores that sell batteries also offer recycling services. Alternatively, check with your local waste management services for battery disposal guidelines. Don’t just toss it in the bin; dispose of it responsibly to do your part for the environment.

Armed with the right tools and knowledge, you’re set to tackle the battery replacement and extend the life of your key fob.

Accessing the Battery Compartment

Having gathered your tools and new battery, you’re ready to pry open your Subaru key fob and expose the old battery for replacement. The key fob’s durability is evident as it resists initial attempts, but don’t be deterred. Your trusty flathead screwdriver or a coin will do the trick. Carefully insert it into the designated slot or notch and twist gently. You’ll feel the case start to give as the two halves begin to separate.

Keep in mind, Subaru key fobs are designed with waterproof features, so the seal might be tighter than expected, ensuring your key’s electronic components are protected from the elements. With a bit of patience and gentle prying, the case will come apart, revealing the battery compartment nestled inside.

Here’s a table that might capture what you’re feeling right now:

Emotion Cause Effect
Relief The case pops open A sense of accomplishment
Anticipation Spotting the old battery Readiness for the next step
Satisfaction Overcoming the tight seal Confidence in the fob’s design

With the battery compartment now accessible, you’re on the verge of victory. Let’s carry that momentum forward as you prepare to install the new battery.

Installing the New Battery

Carefully align the new battery with the positive side facing up, as you’ll typically need to do this for most Subaru key fob models. Gently press the battery down into its compartment, ensuring it fits snugly without any force. You don’t want to damage the delicate electrical contacts. Once it’s securely in place, the hardest part is over.

Now, it’s time to close up the key fob. Snap the two halves back together carefully. If it doesn’t seal with a satisfying click, don’t force it. Check for any obstructions and try again. Replacing the battery won’t mean much if you end up with a broken key fob.

Remember, the new battery’s lifespan depends on several factors, including usage and climate. Expect to go through this process every few years. Always keep a spare battery handy to avoid any inconvenience.

Before tossing the old battery, consider disposal etiquette. Batteries shouldn’t be thrown in the trash due to their toxic components. Look for a recycling program at a local electronics store or a battery disposal kiosk. It’s a simple step that helps protect the environment.

Test your key fob. If it lights up and your Subaru responds, you’ve succeeded. Congratulations, you’re back in business!

Testing and Troubleshooting

After you’ve snapped the key fob case back together, it’s crucial to test its functionality to ensure the new battery is working properly. Approach your Subaru and try to unlock the doors with the key fob. If the doors respond on the first attempt, that’s a good sign. However, if there’s no response, you may need to troubleshoot.

Check the battery’s orientation first; it should be facing the correct way as per the key fob’s design. If it’s correctly installed but the fob is still unresponsive, consider the battery’s charge. Even new batteries can be duds, so it might be worth trying another one.

Signal strength can also affect the fob’s performance. If you’re within a reasonable range and the fob doesn’t work, there might be interference from other devices or structures. Try using the fob at different distances and locations to confirm the signal strength isn’t the issue.

Lastly, keep in mind that battery lifespan varies. Factors such as extreme temperatures or frequent use can shorten it. If your key fob battery fails soon after replacement, these conditions might be the culprit. In such cases, consult your Subaru dealership or a professional for further assistance.
