Step-by-Step Instructions

Step 1: Remove the Internal Key

First, locate the button on the side of your key fob that says “push.” Hold down this button and remove the internal key.

Step 2: Open the Key Fob

With the internal key removed, you will see a keyhole. Perpendicular to the keyhole, there is a small slot in the plastic. Insert your flathead screwdriver into this slot.

Hold the key fob loosely and twist the screwdriver. This action will open the key fob, allowing you to set the two halves apart.

Step 3: Remove the Circuit Board

Inside the key fob, you will see a small circuit board. This is where the battery is housed. Carefully lift out the circuit board to access the battery.

Step 4: Remove the Old Battery

Look for a small opening on the top right of the circuit board. Use the corner of your flathead screwdriver to gently pry out the old battery.

It doesn’t take much force, so be gentle to avoid damaging the circuit board.

Step 5: Insert the New Battery

Take your new CR1632 battery and ensure the positive side is facing up. Click the battery into place in the circuit board.

Step 6: Reassemble the Key Fob

With the circuit board and new battery in place, it’s time to reassemble the key fob. Ensure that the battery is on the bottom side of the device.

Look for a circle on the back of the plastic piece that needs to line up with the battery. Click the two halves of the key fob back together.

Step 7: Replace the Internal Key

The final step is to insert the internal key back into the key fob. Press the buttons to ensure the light comes on, indicating that the battery is charged and the key fob is functioning correctly.

Conclusion

Replacing the battery in your Toyota Avalon key fob is a simple task that can save you time and money. By following these steps, you can ensure your key fob is always ready to use.
