Solution

1. Preparation

Gather necessary tools: small flat-head screwdriver, new key fob battery (CR2032), and a multimeter.
Ensure the vehicle is in a safe location and turned off.

2. Open the Key Fob

Use the small flat-head screwdriver to gently pry open the key fob along the seam.
Carefully separate the two halves without damaging the internal components.

3. Replace the Battery

Remove the old battery, noting its orientation (positive side up).
Insert the new battery (CR2032) in the same orientation.
Ensure the battery is securely seated in its compartment.

4. Reassemble the Key Fob

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

5. Reprogram the Key Fob (if necessary)

Sit inside the vehicle and close all doors.
Insert the key into the ignition and turn it to the "ON" position without starting the engine.
Press the "Lock" button on the key fob for 1 second, then turn the key to "OFF."
Repeat this step two more times (total of three cycles), then press the "Lock" button one more time to complete programming.
