Step-by-Step Guide to Replacing Your 2012 Subaru Key Fob Battery
Subaru has utilized a few different key fob designs over the years. For a 2012 Subaru, you’ll likely encounter one of two main key fob styles: the bulging rectangle shape or the teardrop shape. Knowing which type you have is the first step to a successful battery replacement. If you’re uncertain about your key fob type, your Subaru owner’s manual is the best resource. Once you’ve identified your key fob, you can proceed with the corresponding battery replacement instructions.
Let’s walk through how to replace the battery in each common 2012 Subaru key fob.
Replacing the Battery in a Bulging Rectangle Subaru Key Fob
Battery Type Required: CR2032
This style of key fob is common for many 2012 Subaru models. Here’s how to replace the battery:
-
Remove the Emergency Key: On the back of your key fob, locate a small silver tab. Press and hold this tab to release and remove the metal emergency key.
-
Open the Key Fob Casing: Carefully pry open the key fob. A flathead screwdriver inserted into the seam between the two halves of the fob can be helpful for this step. Gently twist the screwdriver to separate the casing.
-
Locate the Battery: Once opened, you’ll see the round, flat CR2032 battery. Depending on how the fob opens, the battery may be positioned above or below the transmitter circuit board.
-
Replace the Battery: Carefully release the old battery from its housing. Insert the new CR2032 battery, ensuring the positive (+) side is facing upwards. Minimize touching the new battery with your fingers to avoid transferring oils.
-
Reassemble the Key Fob: Snap the two halves of the key fob casing back together until they are securely closed. Re-insert the metal emergency key until it clicks into place.
Replacing the Battery in a Teardrop Shape Subaru Key Fob
Battery Type Required: CR2025
If your 2012 Subaru uses the older teardrop-shaped key fob, the battery replacement process is very similar. The main difference is the battery type and the absence of an emergency key release.
-
Open the Key Fob Casing: Just like the rectangular fob, carefully pry open the teardrop-shaped fob using a flathead screwdriver or a similar tool. Insert it into the seam and gently twist to separate the two halves.
-
Locate the Battery: Inside, you’ll find the CR2025 battery.
-
Replace the Battery: Remove the old CR2025 battery and replace it with a new one, ensuring the positive (+) side is facing upwards. Handle the new battery carefully.
-
Reassemble the Key Fob: Press the two halves of the key fob casing back together until they snap shut.
Troubleshooting: What If a New Battery Doesn’t Solve the Problem?
If you’ve replaced your 2012 Subaru key fob battery and it’s still not working, the issue might be more complex. In some cases, the key fob itself may need replacing, or it might require reprogramming.
For security reasons, purchasing a new Subaru key fob typically needs to be done through an authorized dealership like Subaru North Orlando. Contact us if you suspect your key fob needs to be replaced.
While newer Subaru models with the bulging rectangular fob often require dealership programming, some older models, including certain 2012 Subarus, can be programmed at home. Refer to your owner’s manual for specific programming instructions for your 2012 Subaru model. The original article provided some general programming steps, but always consult your vehicle’s manual for the most accurate procedure.
