Tools You Will Need

Step-by-Step Instructions
Step 1: Flip Out the Key
The first step is to flip out the key from the key fob. This will give you access to the section of plastic that you need to remove.
Step 2: Remove the Plastic Section
Next, use your flathead screwdriver to remove the plastic section from the key fob. Here’s how:
- Insert the screwdriver into the key area.
- Hold up on the top as this section will not move.
- Apply constant pressure to pry off the plastic.
It’s important not to jam the screwdriver in; gentle, consistent pressure will suffice.
Step 3: Locate the Battery Compartment
Once the plastic section is removed, you will see a small hole. This will help you to pry out the old battery.
Step 4: Remove the Old Battery
You can use the flathead screwdriver to remove the old battery. If you have a smaller metal instrument, it might be easier to use. Here’s how:
- Insert the tool into the small hole.
- Gently pry the battery out.
Be careful during this step to avoid damaging any components.
Step 5: Insert the New Battery
Now it’s time to insert the new CR2025 battery. Make sure the positive side (marked with a plus sign) is facing up. Follow these steps:
- Slide the battery under the metal part.
- Snap it into place.
Ensure the battery is seated correctly before proceeding.
Step 6: Reattach the Plastic Section
Finally, reattach the plastic section by lining up the tabs on the side and closing it like a book. Snap it down to secure it.
