Ensure the vehicle is parked in an area where it can be accessed easily.

2. Open the Key Fob

Use the small flathead screwdriver to gently pry open the key fob casing.
Start at the seam and carefully work around to avoid damaging the plastic.

Remove the old battery from the key fob, noting the orientation of the positive (+) and negative (-) sides.
Insert the new CR2032 battery in the same orientation as the old battery.
Ensure the battery compartment is clean and free of debris.

Align the two halves of the key fob casing and press them together until they click securely.
Test the key fob buttons to ensure they are functioning properly before proceeding.
