Solution

1. Preparation

Gather necessary tools such as a small screwdriver, battery replacement kit, and a multimeter if needed.
Ensure you have a replacement battery (typically CR2032) for the key fob.

2. Open the Key Fob

Use a small screwdriver to gently pry open the key fob casing.
Take care to avoid damaging the casing; work around the edges.

3. Replace the Battery

Remove the old battery and note its orientation (positive and negative sides).
Insert the new battery in the same orientation.
Ensure the battery is seated properly in its slot.

4. Reassemble the Key Fob

Align the two halves of the key fob and press them together until they click back into place.
Double-check that the casing is securely closed and there are no gaps.

5. Reprogram the Key Fob (if necessary)

Sit in the driver's seat and close all doors.
Insert the working key fob into the ignition and turn to the ON position without starting the engine.
Wait for 10 seconds, then turn the key back to the OFF position and remove it.
Press any button on the key fob for 30 seconds to allow the vehicle to recognize it.
