1. Preparation

Gather tools: small Phillips screwdriver, flathead screwdriver, multimeter, new battery (CR2032), and OBD-II scanner.
Ensure the vehicle is parked safely and turned off.
Disconnect the vehicle battery if necessary for safety.

2. Open Key Fob

Use a flathead screwdriver to gently pry open the key fob casing.
Be careful not to damage the casing during the process.

3. Inspect and Replace Battery

Remove the old battery, noting the orientation (+/-).
Use a multimeter to check the voltage of the old battery; it should be around 3 volts.
Insert the new battery, ensuring it is oriented correctly as per the markings.

4. Reassemble Key Fob

Snap the key fob casing back together firmly until it clicks into place.
Ensure all seals are tight to prevent water damage.

5. Reprogram Key Fob (if necessary)

Sit in the vehicle with all doors closed.
Insert the key into the ignition and turn it to the ON position (do not start the engine) and back to OFF five times within 10 seconds.
The locks should cycle to indicate programming mode; press any button on the key fob to program it.
Turn the ignition back to OFF to exit programming mode.
