Is your Subaru key fob starting to act up? A common culprit is a low or dead battery. Fortunately, replacing the battery in your Subaru key fob is a straightforward process you can easily do yourself, saving you time and a trip to the dealership. This guide will walk you through the simple steps to get your key fob working like new again.
Before you begin, gather the necessary tools. You’ll typically need a small Phillips head screwdriver or a flathead screwdriver, depending on your specific Subaru key fob model, and a new CR2032 coin battery. These batteries are widely available at most drugstores, supermarkets, and online retailers.
Once you have your tools and new battery, follow these steps to replace your Subaru key fob battery:
- Locate the small notch or opening on your key fob. This is usually found on the side or bottom of the fob.
- Use your screwdriver or a thin pry tool to gently open the key fob casing. Carefully insert the tip into the notch and twist or pry to separate the two halves of the fob. Avoid using excessive force, as you could damage the casing.
- Identify the battery compartment. Once the fob is open, you’ll see the battery compartment, usually holding a CR2032 battery.
- Remove the old battery. Note the orientation of the battery (positive side up or down) before removing it. You can use your fingertip or the tip of a screwdriver to gently pry out the old battery.
- Insert the new CR2032 battery. Place the new battery into the compartment, ensuring it’s in the correct orientation as the old one. You should typically feel it snap into place.
- Reassemble the key fob. Carefully align the two halves of the key fob casing and press them firmly back together until they snap closed. Ensure there are no gaps and the casing is securely sealed.
- Test your key fob. Press the buttons on your key fob to verify that it is now working correctly, locking and unlocking your Subaru.
To maximize the lifespan of your Subaru key fob battery in the future, consider these tips:
- Battery Quality: Opt for reputable brands like Energizer or Duracell for your replacement CR2032 batteries. While less common, battery quality can sometimes vary.
- Usage Habits: Avoid repeatedly pressing the lock/unlock buttons unnecessarily. If your Subaru has touch-sensitive locking or proximity unlocking, utilize these features to minimize battery drain from excessive button presses.
- Proximity to Vehicle: Keep your key fob stored away from your vehicle when at home. Proximity to the vehicle can sometimes lead to faster battery discharge in both the fob and the car. Consider using a Faraday box or storing your fob further away from your Subaru when not in use.
By following these simple steps and tips, you can easily replace your Subaru key fob battery and ensure it functions reliably. This quick DIY task can save you the inconvenience of a dead key fob and keep you on the road.
