Experiencing a dead key fob battery in your 2021 Subaru Outback can be more than a minor inconvenience—it can disrupt your entire day. The frustration of being locked out or unable to start your vehicle is something no driver wants to face. Fortunately, replacing the key fob battery on your 2021 Subaru Outback is a straightforward process you can easily handle yourself. No need for specialized tools or advanced automotive knowledge; this guide will walk you through each step to get you back on the road quickly.
Identifying Your 2021 Subaru Outback Key Fob and Battery Type
Before you begin, it’s important to know the type of key fob your 2021 Subaru Outback uses. For the 2021 Outback model, you’ll typically encounter a bulging rectangle-shaped key fob. This modern design is user-friendly and relatively simple to open for a battery change.
The good news is that this key fob commonly uses a widely available CR2032 battery. These batteries are inexpensive and can be found at most drugstores, grocery stores, and online retailers. Having the correct battery type ensures a smooth and successful replacement.
Step-by-Step Guide to Replacing Your 2021 Subaru Outback Key Fob Battery
Let’s get started with the battery replacement. Follow these simple steps, and you’ll have your 2021 Subaru Outback key fob working like new in no time.
-
Locate the Emergency Key Release: On the back of your 2021 Subaru Outback key fob, you’ll find a small silver tab. This tab is the release for the mechanical emergency key. Press and hold this tab to slide out and remove the metal emergency key. Set the key aside in a safe place.
-
Carefully Open the Key Fob Casing: With the emergency key removed, you’ll see a seam running along the edge of the key fob. This is where you need to gently pry open the casing. A flathead screwdriver or a thin prying tool can be helpful here. Insert the tool into the seam and carefully twist or pry to separate the two halves of the fob. Take your time and avoid applying excessive force to prevent damage to the plastic casing.
-
Identify the Battery Location: Once the key fob is open, you’ll see the internal components. The round, flat CR2032 battery will be visible, either on top of or underneath the transmitter circuit board, depending on how the fob halves separated.
-
Remove the Old Battery: Gently release the old CR2032 battery. In some cases, it might be held in place by small clips or pressure. Note the orientation of the battery – specifically which side is facing up (+ side). This is crucial for installing the new battery correctly.
-
Install the New CR2032 Battery: Take your new CR2032 battery and place it into the battery compartment, ensuring the correct side (usually the positive side marked with ‘+’) is facing upwards, matching the orientation of the old battery. Try to minimize touching the flat surfaces of the battery with your fingers to avoid transferring oils, which can potentially reduce battery life.
-
Reassemble the Key Fob: Carefully align the two halves of the key fob casing and press them firmly back together until they snap securely into place. Ensure there are no gaps and the casing is fully closed.
-
Re-insert the Emergency Key: Slide the metal emergency key back into its slot until it clicks and locks into position.
Testing Your 2021 Subaru Outback Key Fob
With the new battery installed and the key fob reassembled, it’s time to test if everything is working correctly. Try locking and unlocking your 2021 Subaru Outback using the buttons on the key fob. You should also test the remote start and panic button functions to ensure full functionality is restored.
If your key fob responds as expected, congratulations! You’ve successfully replaced the battery in your 2021 Subaru Outback key fob.
What if the New Battery Doesn’t Solve the Problem?
In rare cases, replacing the battery might not resolve the issue. If your 2021 Subaru Outback key fob still isn’t working after a battery replacement, there could be other underlying problems. These could include:
- Key Fob Damage: The internal circuitry of the key fob might be damaged due to impact or moisture.
- Programming Issues: Although less common after just a battery change, the key fob might need to be reprogrammed to your vehicle in some unusual situations.
- Vehicle Receiver Problems: In very rare instances, the receiver in your Subaru Outback that communicates with the key fob could be malfunctioning.
