Solution

1. Preparation

Gather necessary tools: flathead screwdriver, new key fob battery (if needed), and a timer.
Ensure the vehicle is in a safe, well-ventilated area and the ignition is turned off.

2. Access the Key Fob

Use the flathead screwdriver to gently pry open the key fob casing along the seam.
Carefully separate the two halves to access the internal components.

3. Replace the Battery

Remove the old battery and note the orientation (positive and negative sides).
Insert the new battery into the key fob, ensuring correct orientation.

4. Reprogram the Key Fob

Sit inside the vehicle and close all doors.
Insert the key into the ignition and turn it to the "ON" position (not starting the engine).
Turn the ignition back to "OFF" and remove the key.
Within 40 seconds, insert the key again and turn it to the "ON" position and then back to "OFF" two more times.
Remove the key and press any button on the key fob. The doors should lock and unlock, indicating successful programming.

5. Reassemble the Key Fob

Align the two halves of the key fob casing and press them together until they click securely.
Test the key fob to ensure it is working properly.
