Spotting the Signs: Your Key Fob Needs a Battery Change

Alright, before we get our hands dirty, how do you know if your 2020 Subaru Crosstrek key fob battery is actually the problem? Here are some telltale signs:

• Intermittent Functionality: Does your key fob sometimes work, but other times you have to press the buttons multiple times for the doors to unlock or the car to start? This is a classic sign of a weak battery. If you notice your key fob’s performance is inconsistent, this is a strong indication that the battery is nearing the end of its life. Sporadic behavior, such as delayed responses or requiring multiple button presses, points directly to a failing battery. This inconsistency often occurs when the battery's voltage drops below the necessary threshold for reliable operation.
• Reduced Range: If you used to be able to unlock your Crosstrek from a distance, but now you need to be right next to the car, the battery is likely on its way out. A significant decrease in the range of your key fob is a clear signal that the battery is losing its power. This reduced range makes it necessary to be much closer to your vehicle for the key fob to function correctly. This is often one of the first and most noticeable signs of a weak battery.
• Warning Messages: Some Crosstrek models may display a low-battery warning message on the dashboard when the key fob battery is weak. Keep an eye out for any alerts in your car that indicate a problem with the key fob. Modern vehicles are equipped with systems that monitor the key fob's battery health. These systems will alert you when the battery level drops below a certain threshold. Paying attention to these messages can prevent further inconveniences.
• Key Fob Not Working at All: If your key fob simply stops working – no unlocking, no starting – then a dead battery is a likely culprit. Complete failure of the key fob is a strong indicator of a dead battery. If your key fob has stopped working altogether, checking the battery is the first step to resolving the issue. This complete lack of function often requires immediate attention to restore your key fob's usability. This can be particularly inconvenient if it happens at an inopportune time, such as in a parking lot.

If you're experiencing any of these issues, it's time to replace the 2020 Subaru Crosstrek key fob battery. Don't worry, it's a simple fix, and we'll walk you through it.

What You'll Need: Tools and Materials

Okay, guys, before we begin, let's gather our supplies. Thankfully, replacing the 2020 Subaru Crosstrek key fob battery doesn’t require a ton of gear. Here's what you'll need:

• Replacement Battery: This is the star of the show! For the 2020 Subaru Crosstrek key fob, you'll need a CR2032 3V lithium coin cell battery. These are readily available at most stores, including drugstores, supermarkets, and online retailers like Amazon. Make sure to purchase a fresh battery and check the expiration date to ensure optimal performance. The CR2032 battery is the standard battery type for this key fob model, and choosing a reliable brand is essential for ensuring your key fob functions correctly. Always have a spare on hand, just in case!
• Small Flathead Screwdriver or Pry Tool: You'll need this to gently pry open the key fob. A small flathead screwdriver or a plastic pry tool will work perfectly. The screwdriver or pry tool is used to carefully open the key fob without damaging its casing. Make sure to choose a tool that is not too large and has a thin edge to insert into the seam of the key fob. Be gentle to prevent scratches or cracks on the key fob.
• Optional: Microfiber Cloth: This is helpful for keeping everything clean and preventing scratches. A microfiber cloth is useful for wiping down the key fob and preventing fingerprints during the battery replacement process. This ensures that the key fob remains clean and in good condition during the process. This helps in maintaining the aesthetic of your key fob, ensuring it looks and functions as intended. It's a nice touch to keep things looking tidy!

That's it! Now that we have everything we need, let's move on to the actual replacement process. This preparation ensures a smooth and efficient replacement of your key fob battery. Having the right tools and supplies readily available simplifies the process.

Step-by-Step: Replacing Your 2020 Crosstrek Key Fob Battery

Alright, are you ready to get this done? Replacing the 2020 Subaru Crosstrek key fob battery is as easy as pie. Here's a step-by-step guide:

1. Locate the Key Fob Release Button: On the back or side of your key fob, you'll find a small release button. This button allows you to remove the metal key, if your key fob has one. The location of this button varies slightly depending on the specific key fob design, but it is typically easy to find. This initial step is critical as it prepares the key fob for the subsequent steps.
2. Remove the Metal Key (if applicable): Press and hold the release button, then slide the metal key out of the key fob. Set the key aside in a safe place. If your key fob is equipped with a physical key, removing it prevents it from interfering with the process of opening the key fob. This simple step ensures that you can safely and efficiently work on the key fob without damaging its components. It is a necessary step to properly disassemble the key fob and replace the battery.
3. Find the Seam: Look closely at the key fob; you should see a seam where the two halves of the key fob casing meet. The seam is usually located around the edges of the key fob. It is crucial to identify this seam as it is the point where you will insert your screwdriver or pry tool.
4. Open the Key Fob: Carefully insert the tip of your flathead screwdriver or pry tool into the seam. Gently twist the screwdriver or use the pry tool to pry the two halves of the key fob apart. Be patient and work your way around the edges. Avoid using excessive force, as you could damage the key fob. Using the right tool and technique prevents any damage to the key fob's casing. The goal is to separate the key fob into its two halves, allowing access to the battery compartment.
5. Remove the Old Battery: Once the key fob is open, you'll see the battery. Note the battery's orientation (which side is up). Use your screwdriver or pry tool to gently pry the old battery out of its holder. Be extra careful not to damage the battery contacts inside the key fob. This step is a straightforward process, but it requires gentle handling to avoid damaging the key fob's delicate internal components. Proper battery removal ensures that the key fob is prepared for the new battery.
6. Insert the New Battery: Place the new CR2032 battery into the battery compartment, ensuring that it's oriented the same way as the old battery. Make sure the positive (+) side is facing the correct direction. This is a crucial step to ensure that the key fob functions correctly. Double-checking the battery's orientation is a simple yet effective way to avoid potential problems. Incorrect battery orientation will prevent the key fob from working, so take your time and check carefully.
7. Close the Key Fob: Carefully align the two halves of the key fob casing and snap them back together. Ensure that the casing is securely closed. A properly closed key fob protects the internal components from dust and moisture. Make sure that all the edges are aligned before pressing them together. Close the key fob securely to prevent any damage to the internal components.
8. Test the Key Fob: Test your key fob by pressing the lock, unlock, and panic buttons to make sure it's working properly. Test the key fob to ensure that the battery replacement was successful. Confirm that the key fob performs all the intended functions, such as locking and unlocking doors, and activating the panic alarm. This test is a critical step to ensure that the key fob is fully functional after the battery replacement.

And there you have it! You've successfully replaced your 2020 Subaru Crosstrek key fob battery! Congratulations!

Troubleshooting Common Issues

Sometimes, even after replacing the 2020 Subaru Crosstrek key fob battery, things don't go as planned. Here are a few troubleshooting tips:

• Key Fob Still Doesn't Work: Double-check that you inserted the battery correctly, with the positive (+) side facing the right direction. It's a common mistake! If the key fob still doesn't work, try another new battery, as the first one could be faulty. Make sure that the battery is properly seated in the compartment, as a loose connection can also prevent the key fob from functioning. Consider checking for any debris or corrosion in the battery compartment that could interfere with the electrical contacts. In some cases, the key fob may need to be reprogrammed. If all else fails, consult your owner's manual or a Subaru service center.
• Key Fob Range is Still Short: If the key fob unlocks the car, but only when you're close to it, it is still possible that the battery is a bad quality. Ensure you purchased a quality battery from a reputable brand. Check the key fob for any signs of physical damage, such as cracks or water damage, that could affect its range. Sometimes, external interference can reduce the key fob's range, so try using it in a different location to see if it improves. If the range is consistently short, it may indicate a problem with the key fob's internal components, and professional service might be necessary.
• Key Fob Programming Issues: In rare cases, the key fob might need to be reprogrammed after a battery replacement. Consult your owner's manual for instructions on how to reprogram the key fob. Ensure that all the steps are followed correctly to ensure successful reprogramming. If you are not comfortable reprogramming the key fob, take it to your Subaru dealer for assistance. Make sure the key fob is compatible with your car model, as incompatible key fobs will not function correctly.
