Experiencing issues with your Subaru key fob? A common culprit is often a low or dead battery. Don’t worry, replacing the battery in your Subaru key fob is a straightforward process you can easily do yourself. This guide will walk you through everything you need to know about “Subaru Key Fob Battery Replace,” ensuring you’re back on the road quickly and confidently.
Understanding Your Subaru Key Fob Battery
Most Subaru key fobs, across models like the Outback, Forester, Crosstrek, and Impreza, utilize a CR2032 coin battery. This type of battery is readily available at most drugstores, supermarkets, and online retailers. However, battery life can vary depending on several factors.
Factors Affecting Key Fob Battery Life
Several things can impact how long your Subaru key fob battery lasts:
-
Battery Quality: The quality control of CR2032 batteries isn’t always consistent. Occasionally, a battery may be faulty right out of the package. While brands like Energizer and Duracell are generally reliable, even they can sometimes have duds. If you have a battery tester, it’s a good idea to check the new battery before installing it in your fob.
-
Usage Habits: Do you frequently press the lock/unlock buttons on your fob, even when you’re not near the car? This habit can significantly drain the battery faster. Consider utilizing your Subaru’s touch-sensitive door handles or proximity locking/unlocking features if your model is equipped with them. For those moments when you’re away from your vehicle and need to check if it’s locked, the MySubaru/Starlink app can be a more battery-friendly alternative.
-
Proximity to Vehicle: Keeping your key fob too close to your Subaru when you’re at home can also lead to quicker battery depletion. There’s evidence suggesting that continuous communication between the fob and the vehicle, even when idle, can drain both the car’s battery and the fob’s battery. Storing your key fob further away from your car, or using a Faraday cage type box, can help prevent this drain and extend battery life.
Step-by-Step Subaru Key Fob Battery Replacement Guide
Replacing your Subaru key fob battery is a simple process that requires minimal tools. Here’s a general guide; however, always refer to your Subaru owner’s manual for the most accurate instructions for your specific model.
Tools You’ll Need:
- A new CR2032 battery
- A small flathead screwdriver or a similar thin tool (like a key or plastic trim removal tool)
- A soft cloth to protect the fob
Steps:
-
Locate the Notch: On your Subaru key fob, look for a small notch or seam. This is usually located on the side or bottom of the fob.
-
Open the Fob: Using your flathead screwdriver or thin tool, gently insert it into the notch and carefully pry the fob open. Avoid using excessive force to prevent damage to the casing. Sometimes, you may need to slide a release button first before prying; check your owner’s manual if you encounter resistance.
-
Remove the Old Battery: Once the fob is open, you’ll see the CR2032 battery. Note the orientation of the battery (+ side up or down) before removing it. Gently pry the old battery out of its holder.
-
Insert the New Battery: Place the new CR2032 battery into the holder, ensuring it’s in the correct orientation as the old battery. It should snap into place.
-
Close the Fob: Carefully snap the two halves of the key fob casing back together until they are securely closed. Ensure there are no gaps.
-
Test the Fob: Test the buttons on your key fob to ensure they are working correctly. Lock and unlock your Subaru to confirm the new battery is functioning.
Don’t Forget Your Emergency Key
While you’re addressing your key fob battery, it’s also a good time to check your physical emergency key. This mechanical key is usually hidden inside your key fob and can be used to manually unlock your car door if the fob battery is completely dead. It’s crucial to ensure this key works properly. Test it now to avoid being locked out in an unexpected situation.
Choosing the Right Replacement Battery
When purchasing a new CR2032 battery, opt for reputable brands like Energizer or Duracell for better reliability and longevity. While Panasonic batteries are also a good option, they are sometimes harder to find from mainstream retailers and might require online ordering to ensure you get genuine ones.
Extending Your Key Fob Battery Life
To maximize the lifespan of your Subaru key fob battery, consider these tips:
- Reduce unnecessary button presses.
- Utilize touch or proximity locking/unlocking if available.
- Store your key fob away from your vehicle when at home.
- Consider a Faraday box for fob storage.
By following these steps and tips, you can confidently handle your Subaru key fob battery replacement and ensure you always have reliable access to your vehicle. For more car key maintenance tips and solutions, visit keyfobprog.com.
