Step-by-Step Instructions
Step 1: Remove the Internal Key
Look at the side of your key fob. You will see a button labeled “push.” Hold down this button and pull out the internal key. This key will be used for emergency access to your car if the fob battery dies.
Step 2: Open the Key Fob
Next to the keyhole, you will see a small slot in the plastic. Insert your flathead screwdriver into this slot. Hold the key fob loosely and twist the screwdriver. The fob should crack open easily. Use your fingers to pull apart the two halves of the fob.
Step 3: Remove the Circuit Board
Inside the key fob, you will find a small circuit board that houses the battery. Carefully remove this circuit board and set the plastic pieces aside.
Step 4: Extract the Old Battery
At the top of the circuit board, you will see the battery. Insert your flathead screwdriver between the battery and the plastic backing. Apply gentle pressure and wiggle the screwdriver to pop out the old battery.
Step 5: Insert the New Battery
Take your new CR2032 battery and ensure the positive side (marked with a plus sign and text) is facing up. Place the battery behind the two small plastic pieces on the circuit board. Push it down and click it into place.
Step 6: Reassemble the Key Fob
Once the new battery is in place, take the two halves of the key fob and click them back together. Insert the internal key back into its slot. Your key fob is now ready to use.
