Recognizing the Signs of a Weak Key Fob Battery
Before you rush out to buy a new battery, it’s helpful to confirm that a low battery is indeed the problem. Here are the common symptoms indicating that your 2018 Subaru Outback key fob battery is getting weak and likely needs replacement:
- Reduced Range: You need to be much closer to your Subaru Outback than usual for the key fob to lock or unlock the doors. The effective operating distance will noticeably decrease.
- Intermittent Operation: The buttons on your key fob become inconsistent. Sometimes they work, and sometimes they don’t, even when you are at the usual distance from your vehicle.
- Unresponsive Buttons: You press a button on your key fob, but nothing happens. This can occur intermittently at first, then become more frequent until the fob stops working entirely.
- Dashboard Warning Light (If Equipped): Some 2018 Subaru Outback models may have a warning light on the dashboard that specifically indicates a low key fob battery. Check your owner’s manual to see if your vehicle has this feature.
- Difficulty Starting the Vehicle (Push-Button Start): If your 2018 Subaru Outback has push-button start, a very low key fob battery can sometimes cause issues starting the engine. You might need to hold the key fob very close to the start button to initiate the ignition.
If you are experiencing one or more of these symptoms, replacing your 2018 Subaru Outback key fob battery is the first and easiest solution to try.
Identifying the Correct Battery for Your 2018 Subaru Outback Key Fob
Before you begin the replacement process, you’ll need to know the correct type of battery for your 2018 Subaru Outback key fob. The good news is that Subaru key fobs typically use a very common and readily available battery type: the CR2032 3V lithium coin cell battery.
This battery is widely used in small electronic devices and can be purchased at most drugstores, supermarkets, hardware stores, and online retailers. To be absolutely certain, you can:
- Check your owner’s manual: Your 2018 Subaru Outback owner’s manual should specify the correct key fob battery type in the vehicle information section or the key fob section.
- Examine your old battery: Once you open your key fob (as described in the next section), you can check the markings on the existing battery to confirm it is a CR2032.
Using the correct battery type is crucial for proper key fob function and longevity. Ensure you purchase a fresh CR2032 battery from a reputable brand for the best performance.
Step-by-Step Guide to Replacing Your 2018 Subaru Outback Key Fob Battery
Replacing the battery in your 2018 Subaru Outback key fob is a simple process that should take only a few minutes. Here’s a step-by-step guide:
Tools You’ll Need:
- New CR2032 Battery: Ensure you have a fresh CR2032 battery ready.
- Small Flathead Screwdriver or Coin: A small flathead screwdriver or even the edge of a coin will be needed to open the key fob case.
- Soft Cloth (Optional): To prevent scratches on the key fob casing.
Steps:
-
Locate the Notch: Examine your 2018 Subaru Outback key fob. You should see a small notch or slot on the side or bottom of the key fob casing. This is where you will insert your tool to open the case.
-
Insert and Twist: Carefully insert the tip of your small flathead screwdriver or the edge of your coin into the notch. Gently twist the screwdriver or coin. You should feel the key fob case begin to separate. Be gentle to avoid damaging the plastic casing. You may hear a slight clicking sound as the case opens.
-
Open the Case: Once you have gently twisted and separated the case slightly, you should be able to pull the two halves of the key fob case apart with your fingers. Separate the top and bottom halves of the casing to expose the battery compartment.
-
Remove the Old Battery: Carefully remove the old CR2032 battery from its compartment. Note the orientation of the battery (positive side up or down) before removing it. You may be able to gently pry it out with your fingertip or the edge of your screwdriver if it is snug.
-
Install the New Battery: Insert the new CR2032 battery into the battery compartment, ensuring that you install it in the correct orientation (positive side usually facing up, but double-check the markings inside the case or the orientation of the old battery). Push the battery firmly into place until it is securely seated.
-
Reassemble the Key Fob: Carefully align the two halves of the key fob case and press them back together until they snap securely closed. Ensure that the case is fully closed and there are no gaps.
-
Test the Key Fob: Test your key fob by pressing the buttons to lock and unlock your 2018 Subaru Outback. The doors should lock and unlock reliably, indicating that the battery replacement was successful.
Tips for a Smooth Battery Replacement:
- Work on a Clean Surface: Choose a clean, flat surface to work on to avoid losing any small parts.
- Be Gentle: Avoid using excessive force when opening the key fob case to prevent damage.
- Note Battery Orientation: Pay close attention to the orientation of the old battery before removing it to ensure you install the new battery correctly.
- Double-Check Closure: Make sure the key fob case is completely and securely closed after replacing the battery to protect the internal components from dust and moisture.
By following these steps and tips, you can easily replace the battery in your 2018 Subaru Outback key fob and restore its functionality, ensuring you can continue to conveniently access and operate your vehicle.
