Step-by-Step Guide to Replacing Your 2020 Subaru Crosstrek Key Fob Battery
For the 2020 Subaru Crosstrek, you’ll typically encounter a key fob with a bulging rectangular shape. This type of fob is common for this model year and uses a readily available CR2032 battery. Here’s how to replace it:
-
Remove the Emergency Key: Locate the small silver tab on the back of your 2020 Subaru Crosstrek key fob. Press and hold this tab to release and remove the metal emergency key. Set the key aside in a safe place.
-
Open the Key Fob Casing: Carefully pry open the key fob. You’ll notice a seam running around the edge of the fob. Insert a flathead screwdriver or a thin pry tool into this seam. Gently twist or pry to separate the two halves of the fob. Take your time to avoid damaging the plastic casing.
-
Locate the Battery: Once the fob is open, you’ll see the internal components. The flat, round CR2032 key fob battery will be visible. It might be positioned on top of or underneath the transmitter circuit board, depending on how the fob opens.
-
Remove and Replace the Battery: Carefully release the old battery. It might be held in place by small clips. Gently pry it out. Take your new CR2032 battery and pop it into place. Ensure the positive (+) side of the battery is facing upwards. Try to minimize touching the flat surfaces of the new battery with your fingers to avoid transferring oils.
-
Reassemble the Key Fob: Carefully snap the two halves of your 2020 Subaru Crosstrek key fob back together. Press firmly until you hear or feel them click securely into place.
-
Re-insert the Emergency Key: Slide the metal emergency key back into its slot until it clicks and locks.
That’s it! You’ve successfully replaced the 2020 Subaru Crosstrek key fob battery. Test the buttons on your fob to ensure it’s working correctly. Your Crosstrek should now respond to lock, unlock, and panic commands.
What Battery Does a 2020 Subaru Crosstrek Key Fob Need?
As mentioned, the 2020 Subaru Crosstrek key fob battery type you need is a CR2032. This is a common 3V lithium coin cell battery and is widely available at drugstores, supermarkets, auto parts stores, and online retailers. It’s always a good idea to keep a spare CR2032 battery at home so you’re prepared when your key fob battery inevitably needs replacing.
Troubleshooting: What If a New Battery Doesn’t Fix the Issue?
If you’ve replaced the 2020 Subaru Crosstrek key fob battery and your fob still isn’t working, there could be a few other possibilities:
- Incorrect Battery Installation: Double-check that you installed the CR2032 battery with the positive (+) side facing up. Also, ensure the battery is making good contact within the fob casing.
- Key Fob Damage: If your key fob has been dropped, gotten wet, or experienced significant wear and tear, internal damage might be the issue.
- Key Fob Programming: In some rare cases, battery replacement can cause the key fob to lose synchronization with your vehicle. While less common with simple battery swaps, it’s a possibility. The original article mentions a programming procedure, but for newer models like the 2020 Crosstrek, dealership programming is often required for new fobs or in case of programming issues.
- Vehicle Issues: Although less likely, problems with your Subaru Crosstrek’s receiver or car battery could also mimic key fob problems.
If a new 2020 Subaru Crosstrek key fob battery doesn’t solve the problem, it’s best to consult with a professional.
