Step-by-Step Instructions
Follow these steps to replace the battery in your Toyota 4Runner key fob:
Step 1: Open the Key Fob
Look for the small indentation along the seam of the plastic on the side of the key fob. Insert your flathead screwdriver into this area and twist it until you hear a cracking sound. This will separate the back piece of plastic from the key fob.
Step 2: Remove the Inner Component
Insert your flathead screwdriver into the small opening on the top of the key fob. Pry out the inner component and set it aside. You should now see the battery compartment.
Step 3: Locate the Battery
Inside the key fob, you’ll see a small arrow pointing to the battery compartment. Insert your flathead screwdriver into the indentation between the black and clear plastic and twist it to open the compartment further. Continue pulling it apart with your fingers.
Step 4: Remove the Old Battery
Using your flathead screwdriver, gently lift the old CR2016 battery out of its compartment. Dispose of the old battery properly.
Step 5: Insert the New Battery
Take your new CR2016 battery and ensure the positive side with the text is facing up. Click it into place, making sure it sits securely in the compartment.
Step 6: Reassemble the Key Fob
Once the new battery is in place, reassemble the key fob by clicking the inner component back into the outer plastic casing. Press it down firmly to ensure it’s secure.
Step 7: Test the Key Fob
Press one of the buttons on the key fob. If the red light comes on, your new battery is working correctly. You’ve successfully replaced the battery in your Toyota 4Runner key fob.
