What You’ll Need
Before you begin, gather the following materials:
- A new CR2032 battery: This is the standard battery size used in most Subaru Forester key fobs.
- A small flathead screwdriver: This will be used to pry open the key fob.
- A coin or a small, flat object: This will help you push the battery out of its compartment.
Step 1: Locate the Battery Compartment
The battery compartment is typically located on the back of the key fob. Look for a small, rectangular slot or a button that can be pressed to release the back cover.
Step 2: Remove the Key Fob Cover
Use a small flathead screwdriver to gently pry open the back cover of the key fob. Be careful not to damage the plastic housing. Some key fobs may have a small button or tab that you can press to release the cover.
Step 3: Remove the Old Battery
Once the back cover is removed, you’ll see the old battery. Use a coin or a small, flat object to gently push the battery out of its compartment.
Step 4: Insert the New Battery
Take the new CR2032 battery and align it correctly within the battery compartment. The positive (+) side of the battery should face towards the top of the key fob. Gently press the battery into place until it clicks securely.
Step 5: Reassemble the Key Fob
Once the new battery is installed, carefully place the back cover back onto the key fob. Make sure the cover snaps securely into place.
Testing the New Battery
After reassembling the key fob, try to use it to unlock the doors or start the engine. If it works correctly, you’ve successfully replaced the battery.
