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.

5. Close the compartment: Carefully snap the battery compartment closed.
Changing the Battery for a Keyless Entry Remote

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.
