Step-by-Step Instructions
Follow these steps to replace the battery in your Toyota MR2 key fob:
Step 1: Open the Key Fob
First, locate the small slot or indentation along the seam of the key fob. Insert your flathead screwdriver into this slot and twist it gently to crack the key fob open. Set the back cover aside.
Step 2: Remove the Old Battery
Once the key fob is open, you’ll see the old battery. You may need a smaller tool to remove it. While a flathead screwdriver can work, it might be too large and could cause some damage. Instead, use a precision screwdriver or a similar tool like a paper clip, toothpick, or bobby pin.
Insert the tool into the small hole next to the battery and pry it out carefully. The battery should come out easily once you have the right tool.
Step 3: Insert the New Battery
Take your new CR2025 battery and ensure the positive side (marked with a plus sign and text) is facing up. Click the new battery into place.
Step 4: Reassemble the Key Fob
After inserting the new battery, click the two halves of the key fob back together. Ensure everything is securely in place.
Step 5: Test the Key Fob
Finally, test the key fob to ensure it works correctly. Press the buttons and check if the light comes on. If it does, you’ve successfully replaced the battery.
