Step-by-Step Guide

Follow these steps to replace the battery in your Chevrolet Sonic key fob:

Step 1: Remove the Internal Key

Locate the button on the side of your key fob. Hold down this button and pull out the internal key. Keep this key handy as you will need it to open the fob.

Step 2: Open the Key Fob

Insert the internal key into the keyhole, but do not push it in too far. You are aiming to pry off the back section of the plastic casing. Be gentle and apply pressure until you feel the casing start to open. If you push the key in too far, it will get stuck, and the back piece will not move.

Step 3: Remove the Old Battery

Once the key fob is open, you will see the battery. If you have long nails, you might be able to pry it out with your fingers. Otherwise, use the flathead screwdriver to gently lift the battery out. Dispose of the old battery properly.

Step 4: Insert the New Battery

Ensure that your new battery is a CR2032. Place the battery into the slot with the positive side facing down. Snap it into place securely.

If you need to purchase a new battery, you can get one from Amazon.

Step 5: Reassemble the Key Fob

Align the two halves of the key fob carefully, making sure the button is properly seated in its housing. Squeeze the fob back together until it snaps into place. Finally, reinsert the internal key.
