Your Subaru key fob is your passport to your vehicle, but like any electronic device, its battery eventually needs replacing. Knowing how to change out your Subaru key fob battery is a valuable skill that can save you time, money, and frustration. This guide provides a comprehensive step-by-step process to make battery replacement a breeze.
Tools You’ll Need
Before you begin, gather the following tools:
- A small, flat-head screwdriver or a coin: This will be used to pry open the key fob.
- A new CR2032 battery: This is the standard battery used in most Subaru key fobs.
- A pair of tweezers (optional): These can be helpful for handling the small battery.
Step-by-Step Guide
Now that you have your tools ready, let’s get started:
1. Locate the Battery Compartment: Your Subaru key fob likely has a small seam or a release button on the back. Locate this area.
2. Pry Open the Key Fob: Using your flat-head screwdriver or coin, gently pry open the key fob at the seam or release button. Be careful not to apply too much force, as this could damage the key fob.
3. Remove the Old Battery: Once the key fob is open, you’ll see the old battery. Carefully remove it using your fingers or tweezers.
4. Insert the New Battery: Align the new CR2032 battery with the positive (+) and negative (-) terminals inside the key fob. Ensure the battery is properly oriented before pressing it into place.
5. Close the Key Fob: Once the new battery is securely in place, close the key fob. Make sure the halves of the key fob snap together securely.
6. Test the Key Fob: Test your key fob by pressing the unlock, lock, and panic buttons. If the key fob is working properly, you’re all set!
Tips for Success
- Avoid Over-tightening: When closing the key fob, don’t force it shut. Gently snap it closed. Over-tightening can damage the key fob’s casing.
- Proper Disposal: Dispose of the old battery properly. Batteries should not be thrown in the trash. Locate a battery recycling center in your area.
- Know Your Key Fob: Some Subaru key fobs have slightly different designs. If you’re unsure about your specific key fob, consult your owner’s manual or contact your local Subaru dealership.
The Importance of a Working Key Fob
A functioning key fob is vital for your Subaru’s security and convenience. It enables you to:
- Unlock and Lock Your Vehicle: This is the most basic but essential function of a key fob.
- Remote Start Your Vehicle: Some Subaru models offer remote start, allowing you to pre-heat or cool your car before you even step inside.
- Activate the Panic Alarm: The panic button is a valuable safety feature, allowing you to sound the car’s alarm in an emergency.
Troubleshooting Common Issues
Sometimes, even after replacing the battery, your key fob might not work correctly. Here are some common issues and solutions:
- Battery Contact: Ensure the new battery is properly seated and making good contact with the terminals.
- Key Fob Programming: If your key fob is not responding after a battery change, it may need to be reprogrammed. Consult your owner’s manual or contact your Subaru dealer for programming instructions.
- Key Fob Damage: If your key fob has been dropped or damaged, it could be malfunctioning. Contact your Subaru dealer for repair or replacement options.
The End of the Line: When to Replace Your Key Fob
While a new battery can breathe life back into your key fob, eventually, the key fob itself may reach the end of its lifespan. Here are some signs that it’s time to replace your key fob:
- Frequent Battery Changes: If you’re replacing the battery every few months, it might be a sign that the key fob’s internal components are failing.
- Unreliable Performance: If the key fob is frequently unresponsive or unreliable, it’s time for a new one.
- Physical Damage: If your key fob is cracked, broken, or severely worn, it’s best to replace it.
