Experiencing a finicky Subaru key fob that just won’t cooperate? It might be time for a quick battery swap! While it might seem intimidating, changing the battery on your Subaru key fob is actually a simple task that you can handle yourself. In this comprehensive guide, we’ll walk you through each step of the process, arming you with the knowledge to get your key fob back in action.
Identifying When Your Subaru Key Fob Battery Needs Replacing
Before we dive into the how-to, let’s discuss recognizing the telltale signs of a dying key fob battery:
- Decreased Range: Are you finding yourself standing closer and closer to your car to unlock it? This diminished range is a classic sign that your key fob battery is losing power.
- Intermittent Functionality: If your car only responds to your key fob sporadically, it’s a clear indicator that the battery is on its last legs.
- Dashboard Warning Light: Some Subaru models will display a warning light on the dashboard, explicitly indicating a low key fob battery.
What You’ll Need
Here’s a quick checklist of the essential items you’ll need for this DIY project:
- Replacement Battery: Subaru key fobs typically use a CR2032 battery. These are readily available at most hardware and electronics stores.
- Small Flat-Head Screwdriver: This will be used to open the key fob casing.
- Optional: Small Container or Tray: This can be helpful for keeping the small parts organized during disassembly.
Step-by-Step Guide to Changing the Battery
Follow these straightforward steps to replace your Subaru key fob battery:
- Locate the Key Fob Release: On the back of your Subaru key fob, find the small release button or switch.
- Release the Metal Key: Press the release button and gently slide the metal key out of the fob.
- Separate the Fob Halves: Using your flat-head screwdriver, carefully pry open the key fob casing. Start at the seam where the metal key was inserted, applying gentle pressure until the two halves separate.
- Remove the Old Battery: The CR2032 battery will be situated within one of the fob halves. Carefully remove it, paying attention to its orientation.
- Insert the New Battery: Place the new CR2032 battery into the fob, ensuring it sits in the same position as the old one, with the positive (+) side facing up.
- Reassemble the Fob: Align the two halves of the key fob and press them firmly together until you hear a click, indicating they are securely closed.
- Reinsert the Metal Key: Slide the metal key back into its slot on the fob.
Testing Your New Key Fob Battery
Once you’ve replaced the battery, it’s crucial to ensure everything is functioning correctly:
- Lock and Unlock Test: Try locking and unlocking your Subaru using the key fob buttons.
- Range Test: Walk a short distance away from your car and try using the key fob again to test the range.
“Always use high-quality replacement batteries for your Subaru key fob,” advises John Miller, Senior Automotive Technician at Miller’s Auto Repair. “Using cheap, off-brand batteries might seem like a cost-effective solution, but they can often lead to performance issues and shorter lifespans.”
Troubleshooting: What to Do If Your Key Fob Still Doesn’t Work
If you’ve replaced the battery and your Subaru key fob is still unresponsive, consider these troubleshooting tips:
- Check Battery Orientation: Double-check that you’ve inserted the new battery correctly, with the positive (+) side facing up.
- Inspect the Battery Contacts: Ensure the metal contacts within the key fob, where the battery connects, are clean and free of debris. If necessary, use a cotton swab and rubbing alcohol to clean them gently.
- Reprogramming: In some cases, your Subaru key fob might need to be reprogrammed after a battery change. Consult your owner’s manual for specific instructions or seek assistance from a qualified automotive locksmith or dealership.
