A dead key fob battery can leave you stranded, unable to unlock your Subaru or start the engine. Luckily, replacing it is a simple DIY task that takes only a few minutes and requires no special tools. This guide provides a step-by-step walkthrough on how to change the battery in your Subaru key fob, ensuring you’re back on the road in no time.
Identifying Your Subaru Key Fob Type
Before you begin, it’s crucial to identify your specific Subaru key fob model. Different models may have slight variations in battery replacement procedures. Here are the two common types:
1. Traditional Key Fob with Flip Key: This type features a physical key that flips out from the fob.
2. Smart Key Fob (Keyless Entry): This type is sleeker and doesn’t have a visible physical key.
Once you’ve identified your key fob type, you can gather the necessary materials and proceed with the battery replacement.
What You’ll Need
- A new CR2032 battery: This is the most common type used in Subaru key fobs.
- A small flat-head screwdriver: This is used to pry open the key fob casing.
Step-by-Step Guide to Changing the Battery
Step 1: Release the Emergency Key
- Traditional Key Fob: Locate the small release button or switch on the back of the fob. Press it to release and remove the physical key.
- Smart Key Fob: Look for a small slot or indentation on the fob’s edge. Insert the tip of the flat-head screwdriver (or your fingernail if possible) and gently pry open the emergency key slot cover. Slide the key out.
Step 2: Open the Key Fob Casing
- Insert the flat-head screwdriver into the seam where the two halves of the key fob casing meet.
- Gently twist the screwdriver to pry open the casing. Be careful not to apply excessive force, as this might damage the fob.
Step 3: Replace the Battery
- Inside the fob, you’ll see the CR2032 battery. Carefully remove it, noting the orientation (positive (+) side facing up).
- Place the new CR2032 battery in the same orientation as the old one.
Step 4: Reassemble the Key Fob
- Align the two halves of the key fob casing and press them together until they snap securely back into place.
- Reinsert the emergency key into its slot.
Step 5: Test the Key Fob
- Test all the buttons on your key fob (lock, unlock, panic, etc.) to ensure it’s functioning correctly.
Troubleshooting Tips
If your key fob still doesn’t work after replacing the battery, here are some things to check:
- Battery Orientation: Ensure the new battery is inserted with the positive (+) side facing up.
- Battery Contacts: Over time, the battery contacts inside the fob might get dirty or corroded. Clean them gently with a cotton swab and rubbing alcohol.
- Programming Issues: In rare cases, you might need to reprogram your key fob to your Subaru after a battery change. Refer to your owner’s manual for instructions or contact your local Subaru dealership.
“A common mistake is inserting the new battery upside down,” says John Davis, a seasoned automotive electrician. “Always double-check the orientation before closing the fob.”
Conclusion
Changing the battery in your Subaru key fob is a straightforward task that anyone can handle. By following these simple steps and keeping a spare CR2032 battery on hand, you can avoid the inconvenience of a dead key fob and ensure seamless access to your Subaru whenever you need it.
