Step-by-Step Instructions

1. Remove the Internal Key

First, locate the button on the side of the key fob that says “push.” Press and hold this button to release the internal key. Set the key aside for now.

2. Open the Key Fob

Next, identify the indentation in the plastic near the keyhole. Insert your flathead screwdriver into this indentation. Twist the screwdriver to remove the back cover of the key fob.

3. Remove the Circuit Board

Carefully lift the circuit board to reveal the battery housing. Be gentle to avoid damaging any components.

4. Remove the Old Battery

Using the same flathead screwdriver, insert it under the battery. Gently wiggle and twist the screwdriver to pry the battery out. Do not use excessive force to avoid breaking the housing.

5. Install the New Battery

Take the new CR2032 battery and ensure the positive side with the text is facing up. Click the battery into place within the housing.

6. Reassemble the Key Fob

Place the circuit board back into the rubber part of the key fob. Click the back cover onto the key fob until it is secure. Finally, reinsert the internal key.
