Step-by-Step Instructions

Follow these steps to replace the battery in your Toyota 4Runner key fob.

Step 1: Remove the Internal Key

First, locate the button on the side of the key fob. Hold this button down and pull out the internal key. This key will be used later to open the key fob.

Step 2: Open the Key Fob

With the internal key removed, you will notice a keyhole and a perpendicular indentation across from it. Insert your flathead screwdriver into this indentation and twist to open the key fob.

Step 3: Separate the Key Fob Halves

Carefully pull apart the key fob. Be cautious not to flip it over, as the buttons may fall out. Set the rubber component facing up to avoid any issues.

Step 4: Remove the Circuit Board

Using the corner of your flathead screwdriver, gently lift up the circuit board and set it aside. Underneath the circuit board, you will find the battery.

Step 5: Remove the Old Battery

With the circuit board oriented correctly, locate the small opening in the top right corner. Insert your screwdriver, hold the battery down, and pry it out.

Step 6: Insert the New Battery

Take your new CR1632 battery and ensure the positive side (the side with the text) is facing up. Click it into place, making sure it is secure.

Step 7: Reassemble the Key Fob

Place the back piece of plastic with the battery sitting on top of the circle. Click the front piece of plastic back together, ensuring everything is aligned correctly.

Step 8: Reinsert the Internal Key

Finally, put the internal key back into the key fob. Press the buttons to check if the light comes on, indicating the battery is working.
