Recognizing the Signs: When Your Key Fob Needs Attention
The Subaru Outback has earned a reputation as a reliable and versatile vehicle, a popular choice for adventurous drivers and families alike. Its blend of rugged capability, spacious interiors, and advanced technology makes it a comfortable and capable companion for daily commutes and weekend getaways. A key part of the modern Outback experience is the convenience of the key fob, the small, often overlooked device that unlocks a world of features, from remote start to central locking. But what happens when the magic stops working? One of the most common issues that can plague a Subaru Outback 2018 owner is a dead or dying key fob battery, leaving you stranded or significantly inconvenienced. This guide is designed to provide you with all the information you need to quickly and easily replace the Subaru Outback 2018 key fob battery, ensuring your remote control continues to function flawlessly.
When this seemingly simple device stops working, it can disrupt your daily life. Fortunately, replacing the Subaru Outback 2018 key fob battery is a straightforward process you can easily complete at home. This article will walk you through every step, from recognizing the symptoms of a failing battery to replacing it and testing the key fob’s functionality.
Reduced Range of Key Fob Functionality
One of the most noticeable signs of a low battery is a reduced range of key fob functionality. You might find yourself needing to be closer to the vehicle than usual for the key fob to lock or unlock the doors, or for the remote start to engage. Initially, this might seem like a minor inconvenience, but as the battery degrades further, the range will continue to diminish.
Key Fob Not Working At All
Another clear indication is when the key fob stops working altogether. This means you might not be able to lock or unlock the doors using the key fob buttons, or use the remote start function. This can be especially problematic if you are carrying groceries or other items, or if you find yourself in a hurry. In extreme cases, the car may even refuse to start when the key fob battery is critically low, potentially due to an inability to read the immobilizer chip in the key fob.
Warning Messages on the Dashboard
Some Subaru Outback 2018 models may display warning messages on the dashboard indicating a low battery in the key fob. The exact message can vary depending on the trim level and the vehicle’s software, but it will likely be a clear prompt to replace the battery. Heeding these alerts is crucial to avoid becoming stranded.
Difficulty Starting the Car
Finally, a weak or dead key fob battery can sometimes result in difficulty starting the car. This typically happens if the key fob struggles to communicate with the vehicle’s immobilizer system. You might experience delays in starting, or you might have to hold the key fob closer to the ignition button.
If you experience any of these issues, it’s highly likely that your Subaru Outback 2018 key fob battery is either weak or completely dead. Don’t delay in addressing these symptoms. A replacement battery is a relatively inexpensive and easy fix that will restore your key fob’s functionality and your peace of mind.
Gathering the Essentials: What You Need to Get Started
Before you begin changing your Subaru Outback 2018 key fob battery, it’s essential to gather all the necessary tools and materials. Having everything readily available will streamline the process and make it much easier. Fortunately, the list is short and simple:
New CR2032 Battery
The most critical item you’ll need is a new CR2032 battery. This is the specific battery type used in the Subaru Outback 2018 key fob. It’s a small, coin-shaped lithium battery widely available at most auto parts stores, electronics retailers, drugstores, and even online marketplaces like Amazon. Be sure to check the expiration date on the battery package to ensure you’re getting a fresh battery. It is generally recommended to buy quality batteries from reputable brands to avoid any premature battery failures.
Small Flathead Screwdriver or Pry Tool
You’ll also need a small flathead screwdriver or a pry tool. This will be used to carefully open the key fob case. A small, thin screwdriver is ideal, but a pry tool specifically designed for electronics can also work. Alternatively, you can use a very thin knife, but be extremely cautious to avoid damaging the key fob.
Microfiber Cloth (Optional)
While not absolutely necessary, a microfiber cloth is a good idea. You can use it to clean the key fob and the battery compartment, and to protect the key fob from scratches during the opening and closing process.
Once you have these items ready, you’re fully prepared to replace your Subaru Outback 2018 key fob battery.
Opening the Key Fob: Accessing the Battery Compartment
Now that you have the necessary materials, it’s time to open the Subaru Outback 2018 key fob and access the battery. The process is generally the same across different key fob designs, but variations do exist. Here’s a step-by-step guide:
Locating the Notch or Seam
Begin by examining the edges of your key fob. Look for a small notch or seam that indicates where the two halves of the key fob case separate. This is usually located along the side of the key fob, near the key ring or the buttons.
Prying Open the Key Fob
Carefully insert the small flathead screwdriver or pry tool into this notch. Apply gentle pressure, prying open the key fob. The goal is to create a small gap between the two halves. You may need to wiggle the screwdriver gently to loosen the casing. Avoid applying excessive force, which could damage the key fob.
Separating the Halves
Once you’ve created a small gap, you can usually continue to gently pry the two halves of the key fob apart, working your way around the edges. Be patient and persistent. Some key fobs might be more resistant to opening than others.
Considering Internal Components
Be mindful of the internal components as you open the key fob. These often include the circuit board and other delicate electronic parts. Try to work on a clean, flat surface to avoid losing small components.
As you separate the halves, you will expose the battery compartment, giving you access to the battery.
Key Fob Styles
It’s worth noting that there are a few different styles of key fobs used for the Subaru Outback 2018. In some key fobs, you may need to use the key (if available) to help pry the key fob apart. Another common style has a small button or release mechanism you need to press to separate the key fob. If you are having trouble, consult your owner’s manual. Alternatively, search online for videos specific to your Subaru Outback 2018 key fob model. This can provide visual guidance that makes the process easier.
Removing the Old Battery: Preparing for the New
With the key fob open, you are ready to remove the old battery. This step is typically straightforward:
Finding the Battery’s Position
Carefully locate the battery’s position within the key fob. It’s usually housed in a small compartment, often held in place by small clips or retaining tabs.
Removing the Old Battery
Using your fingers or a small tool, carefully remove the old battery. Be gentle to avoid damaging the key fob. The method for removing the battery will vary slightly depending on the key fob design. Some key fobs have a small plastic tab you can use to lift the battery out. Others may have clips that need to be gently pried away.
Checking the Orientation
Pay close attention to how the old battery is positioned in the compartment. Note the orientation of the battery. The positive (+) side is often indicated with a “+” symbol and should be facing up or down in the key fob.
Cleaning the Compartment
Before you proceed, clean the battery compartment using a microfiber cloth to remove any dirt or debris that might have accumulated. This ensures a good connection with the new battery.
Installing the New Battery: The Reversal of Fortune
Now, it’s time to insert the new battery:
Correct Polarity
Take the new CR2032 battery and note the positive (+) and negative (-) markings. Ensure that you insert the new battery with the correct polarity. This is crucial for the key fob to function correctly. In most key fobs, the positive (+) side of the battery faces upwards.
Inserting the New Battery
Carefully insert the new battery into the compartment, aligning it with the correct polarity. Ensure it’s securely seated. If the battery isn’t inserted properly, the key fob may not work and you might need to repeat the previous steps.
Secure Placement
Make certain that the battery is firmly in place and making good contact with the terminals. The retaining clips should hold the battery securely within the compartment.
Closing the Key Fob: Reassembling the Parts
Once the new battery is installed, you can reassemble your Subaru Outback 2018 key fob:
Aligning the Halves
Align the two halves of the key fob. Ensure that all the internal components are properly positioned. Be careful not to pinch any wires or circuit boards during the process.
Closing the Fob
Gently snap or press the key fob back together. The halves should fit snugly. You may hear a clicking sound as the key fob closes.
Ensuring a Secure Fit
Check for a secure fit. Make sure that the key fob case is completely closed and that there are no gaps between the two halves.
With the key fob reassembled, you are ready to test its functionality.
Testing the Key Fob: Checking the Functionality
After completing the battery replacement, it’s time to test the key fob to ensure it’s working correctly:
Testing Functions
Test the key fob’s functionality. Start by trying the lock and unlock buttons on your car’s doors. The doors should lock and unlock smoothly.
If your Subaru Outback 2018 is equipped with remote start, test that function as well. The engine should start remotely when you press the appropriate button on the key fob.
If the key fob has other functions, such as opening the trunk or operating the power liftgate, test those functions as well.
If any of the key fob functions are not working, go back to the previous steps, ensuring that you installed the battery correctly and that the key fob is properly reassembled. Double-check that you’re using a fresh, properly specified battery.
Battery Life and Replacement Reminders
Now that you’ve successfully changed the Subaru Outback 2018 key fob battery, you might wonder how long the new battery will last.
Average Battery Life
The average battery life for a key fob is around 1 to 2 years, although this can vary based on the key fob usage and other factors.
Factors Affecting Battery Life
Several factors can affect battery life. Frequent use, especially of the remote start function, will deplete the battery more quickly. Extreme temperatures, both hot and cold, can also negatively impact battery life.
Extending Battery Life
To get the most life out of your key fob battery, it’s wise to take a few precautions. Avoid keeping the key fob in extreme temperatures, such as on the dashboard in direct sunlight or in a freezing car. Consider storing your key fob away from other electronic devices that might interfere with its signal.
Safety Reminders: Handling the Components With Care
