Step-by-Step Instructions

Step 1: Locate the Indentation

First, find the small indentation on your key fob. This indentation is near the key ring attachment point.

Next, insert your flathead screwdriver into the indentation.

Gently wiggle the screwdriver and twist it to open the fob.

Now that the key fob is open, you will see the old CR2032 battery.

Use your finger or the screwdriver to push the old battery out.

Dispose of the old battery properly.

Step 5: Insert the New Battery

Take your new CR2032 battery and ensure the positive side faces up.

The text on the battery should be visible when placed correctly.

Slide the new battery into the slot with your finger.

Step 6: Reassemble the Key Fob

After the new battery is securely in place, click the two halves of the key fob back together.

Ensure it snaps shut firmly to protect the internal components.
