## How to Change the Battery in a Subaru Key
If you own a Subaru vehicle, you may have encountered the need to change the battery in your key fob. The key fob is a small electronic device that allows you to remotely lock or unlock your car doors. Over time, the battery in your Subaru key may lose its charge, resulting in a less responsive or non-functional key fob. Fortunately, the process of changing the battery in a Subaru key is relatively simple and can be done at home with a few basic tools. In this article, we will guide you through the step-by-step process of changing the battery in your Subaru key.
### Getting Started: Gathering the Necessary Tools
Before you begin the battery replacement process, you will need to gather a few tools and materials:
1. Replacement battery: The first step is to determine the type of battery your Subaru key fob requires. Most Subaru key fobs use a CR2032 battery, but it’s always best to refer to your vehicle’s owner’s manual for the specific battery type.
2. Small screwdriver: The next tool you will need is a small screwdriver, preferably a Phillips-head screwdriver. This will be used to remove the screws that hold the key fob casing together.
3. Soft cloth or towel: To protect the key fob from scratches or damage, have a soft cloth or towel on hand to place the key fob on during the battery replacement process.
Once you have gathered these tools, you are ready to begin changing the battery in your Subaru key.
### Step 1: Removing the Key Fob Case
1. Locate the small slot or indentation on the edge of your key fob. This is usually located near the keyring attachment.
2. Insert the small screwdriver into the slot and gently pry open the key fob case. Apply gentle pressure to release the clips or tabs that hold the case together.
3. Slowly separate the two halves of the key fob case. Be cautious not to damage any internal components or buttons. If necessary, wiggle the screwdriver gently to ease the separation.
4. Once the case is fully open, set the screws aside in a safe place. Be sure not to lose them, as you will need them when reassembling the key fob.
### Step 2: Removing the Old Battery
1. Locate the battery compartment inside the key fob. The battery compartment is typically a small rectangular slot or holder.
2. Carefully remove the old battery from the compartment. You may need to use the screwdriver or your fingernail to gently pry it out.
3. Take a moment to inspect the battery compartment for any signs of corrosion or debris. If present, use a clean, dry cloth to remove any residue before proceeding.
### Step 3: Installing the New Battery
1. Take the new battery and ensure that the positive (+) side is facing up. This is usually indicated on the battery itself or inside the key fob.
2. Insert the new battery into the battery compartment, making sure it is securely seated. You may hear a slight click when the battery is properly inserted.
### Step 4: Reassembling the Key Fob
1. Align the two halves of the key fob case together, ensuring that all buttons and components are properly aligned.
2. Carefully press the two halves of the key fob case together, applying gentle pressure until they snap into place.
3. Once the case is securely closed, locate the screws that were removed earlier. Use the screwdriver to firmly tighten the screws, but be careful not to overtighten them and strip the threads.
### Step 5: Testing the Key Fob
1. After replacing the battery and reassembling the key fob, it’s time to test its functionality.
2. Stand near your vehicle and press the buttons on the key fob to lock and unlock the doors. Ensure that all buttons are responsive and the key fob is functioning properly.
Congratulations! You have successfully changed the battery in your Subaru key fob. By following these simple steps, you can restore the functionality of your key fob without the need for professional assistance.
