Identifying the Battery Compartment
The first step is to locate the battery compartment on your Subaru key fob. This can vary depending on the model year and style of your key fob.
- For newer Subaru key fobs: The battery compartment is often located on the back of the key fob, and it may be marked with a small arrow or a symbol indicating a battery.
- For older Subaru key fobs: The battery compartment might be located on the side of the key fob.
Opening the Key Fob
Once you’ve located the battery compartment, you’ll need to open it. This is typically done by using a small flathead screwdriver or coin to pry open the key fob.
- Carefully insert the screwdriver or coin into the small gap between the two halves of the key fob.
- Gently pry the two halves apart. You don’t need to use excessive force, as the key fob is designed to come apart easily.
Removing the Old Battery
Once the key fob is open, you’ll see the old battery. It should be held in place by a small spring or a clip.
- Carefully remove the old battery. Note the direction of the positive and negative terminals on the battery, as this will be important when inserting the new battery.
Inserting the New Battery
With the old battery removed, you can now insert the new battery.
- Make sure the positive and negative terminals of the new battery are aligned correctly.
- Gently press the new battery into place. It should snap in securely.
Closing the Key Fob
Once the new battery is in place, you can close the key fob.
- Make sure the two halves of the key fob are aligned correctly.
- Gently press the two halves together. They should snap shut securely.
Testing the Key Fob
After you’ve closed the key fob, it’s important to test it to make sure the new battery is working properly.
- Press the unlock button on the key fob. The car doors should unlock.
- Press the lock button on the key fob. The car doors should lock.
- If your key fob has a panic button, press it. The car horn should sound.
If the key fob is working properly, you’re all set. If not, double-check that the battery is installed correctly. If the problem persists, consult your Subaru dealership or a qualified mechanic.
Key Fob Battery Life and Maintenance
