Identifying Your Subaru Key Fob Type

Before diving into the battery replacement process, it’s crucial to identify the specific type of key fob you have. Subaru has produced various key fob designs over the years, each with its own unique battery compartment access method. Here are some common Subaru key fob types:

  • Standard Key Fob: This type features a single button for unlocking and locking the doors, typically with a small, separate button for the panic alarm.
  • Keyless Entry Remote: These key fobs often include additional buttons for trunk release, remote start, or other advanced features.
  • Smart Key Fob: These fobs are more advanced, offering keyless entry and push-button start functionality. They typically have a more streamlined design without visible buttons.

Gather Your Supplies

Before you begin, ensure you have the following items readily available:

  • A new CR2032 battery: Most Subaru key fobs use a CR2032 battery, which is readily available at most electronics stores and online retailers.
  • A small screwdriver: You’ll need a small, flat-head screwdriver to open the key fob’s battery compartment.
  • A clean cloth: This will help prevent dust and debris from entering the key fob while you’re working.

Changing the Battery for a Standard Key Fob

For standard Subaru key fobs, the battery replacement process is straightforward:

1. Locate the battery compartment: Look for a small seam or groove running around the perimeter of the key fob. This is where the battery compartment is located.
2. Open the compartment: Use your small screwdriver to carefully pry open the battery compartment. Be gentle to avoid damaging the key fob.
3. Remove the old battery: The old battery will be held in place by a small spring. Simply lift the battery out.
4. Insert the new battery: Place the new CR2032 battery into the compartment, ensuring the positive (+) side faces up.
5. Close the compartment: Carefully snap the battery compartment closed.

Changing the Battery for a Keyless Entry Remote

Keyless entry remotes often require a slightly different approach:

1. Identify the release button: Look for a small button or tab on the key fob. This button is typically located on the side or bottom of the fob.
2. Press the release button: Gently press the release button and simultaneously pull the key fob apart.
3. Remove the old battery: The old battery will be held in place by a small spring. Carefully lift it out.
4. Insert the new battery: Place the new CR2032 battery into the compartment, ensuring the positive (+) side faces up.
5. Reassemble the key fob: Carefully snap the key fob back together.

Changing the Battery for a Smart Key Fob

Smart key fobs often have a more intricate design, but the battery replacement process is still relatively simple:

1. Locate the release button: Smart key fobs typically have a small release button located on the side or bottom of the fob.
2. Press the release button: Gently press the release button and simultaneously pull the key fob apart.
3. Remove the old battery: The old battery will be held in place by a small spring. Carefully lift it out.
4. Insert the new battery: Place the new CR2032 battery into the compartment, ensuring the positive (+) side faces up.
5. Reassemble the key fob: Carefully snap the key fob back together.

Important Tips for Battery Replacement

  • Handling the battery: Always handle the battery with clean hands to avoid contaminating the key fob’s internal components.
  • Battery disposal: Properly dispose of the old battery. Check your local recycling regulations for disposal guidelines.
  • Testing the new battery: After replacing the battery, test the key fob’s functionality by locking and unlocking your car.

Troubleshooting Common Issues

If you’re experiencing problems with your key fob after replacing the battery, here are a few common issues and their solutions:

  • Key fob not working: Ensure the new battery is correctly installed with the positive (+) side facing up.
  • Key fob range is limited: If the key fob’s range is still limited, the battery might be faulty. Try replacing it with a new battery.
  • Key fob not responding: If the key fob is not responding at all, the key fob itself might be damaged. Consult a Subaru dealership or a qualified mechanic for assistance.

Ensuring Longevity of Your Key Fob Battery

To prolong the life of your key fob battery, follow these helpful tips:

  • Avoid extreme temperatures: Store your key fob in a cool, dry environment to prevent battery degradation.
