Step-by-Step Process

Step 1:

Locate the seam on the key fob where the two halves meet.

Be careful while using the plastic opening tool as it can slip and hit you as you try to pry open the key fob.

To open the key fob gently pull each half apart.

Use a plastic opening tool to gently push the battery out of the battery holder.

Step 4:

Slide the new CR2032 battery in with the + (plus/positive) side facing upwards.

Put the two halves together.

Push evenly across the key fob to connect the two halves.

Test the key fob to see if it works.

The yellow light indicator on the car shows that the key fob works.
