Are you experiencing a frustratingly short range on your Subaru key fob? Or perhaps the dreaded “click, click, click” sound when you try to unlock your car? These are telltale signs that your key fob battery needs replacing. While it may seem daunting, changing the battery in your Subaru key fob is a simple task that you can easily handle yourself. This guide will walk you through the process step-by-step, ensuring a smooth and hassle-free battery replacement.
Identifying the Battery Type
Before you begin, you’ll need to know what type of battery your Subaru key fob uses. Most Subaru key fobs utilize a CR2032 battery, a small, flat, coin-shaped battery. However, it’s always a good idea to double-check your owner’s manual or the back of your key fob for confirmation.
Gathering Your Supplies
To replace your key fob battery, you’ll need:
- A new CR2032 battery: These are readily available at most electronics stores, supermarkets, and online retailers.
- A small, flat-head screwdriver: This is used to pry open the key fob casing.
- Optional: A pair of tweezers: These can be helpful for removing the old battery.
Step-by-Step Battery Replacement Guide
Now that you have everything you need, let’s get started:
1. Locate the Battery Compartment: On most Subaru key fobs, the battery compartment is located on the back of the fob, typically near the Subaru logo. There will be a small seam or a notch that indicates where to pry open the casing.
2. Open the Key Fob: Using your small, flat-head screwdriver, gently insert it into the seam or notch and pry open the key fob casing. Be careful not to apply too much force, as you could damage the key fob.
3. Remove the Old Battery: Once the casing is open, you’ll see the old battery. Carefully remove the battery using your fingers or tweezers. Dispose of the old battery properly according to your local recycling guidelines.
4. Insert the New Battery: Take the new CR2032 battery and carefully align the positive (+) side with the corresponding marking inside the battery compartment. Gently press the battery into place until it clicks securely.
5. Close the Key Fob: Once the new battery is installed, carefully close the key fob casing. Make sure the edges of the casing are properly aligned and snap together securely.
Troubleshooting and Tips
If your key fob still doesn’t work after replacing the battery, try the following:
- Check the battery: Ensure the new battery is installed correctly and that the positive (+) side is facing the correct direction.
- Clean the battery contacts: Use a cotton swab dipped in rubbing alcohol to clean any dirt or debris from the battery contacts on both the key fob and the battery.
- Reset the key fob: Some Subaru key fobs have a reset button. Consult your owner’s manual for instructions on how to reset your specific key fob.
Maintaining Your Key Fob Battery
Here are a few tips to help extend the life of your key fob battery:
- Avoid extreme temperatures: High heat and extreme cold can shorten the lifespan of your battery. Keep your key fob out of direct sunlight and away from extreme temperatures.
- Turn off the key fob when not in use: If you’re not using your key fob, turn it off to conserve battery life.
- Replace the battery regularly: Even if your key fob is still working, it’s a good idea to replace the battery every 1-2 years to prevent it from suddenly dying.
