1. Preparation

Gather tools: small flathead screwdriver, multimeter, and a replacement battery (CR2032 or as specified).
Safety warning: Ensure the vehicle is in a safe, secure area before starting any repairs.

2. Inspect and Replace Key Fob Battery

Remove the key fob casing:
- Use a small flathead screwdriver to gently pry open the key fob casing along the seam.
Check battery:
- Remove the old battery and inspect it for corrosion or damage.
- Use a multimeter to check battery voltage; it should be around 3 volts for a new battery.
Install new battery:
- Place the new battery in the correct orientation (positive side facing up).
Reassemble the key fob:
- Snap the casing back together securely.

3. Test Key Fob Functionality

Stand close to the vehicle and press the lock/unlock buttons on the replaced key fob.
Observe if the vehicle responds to the key fob commands.

4. Reprogram Key Fob (if necessary)

If the key fob still does not work, it may need reprogramming:
- Insert the key into the ignition and turn to the "ON" position without starting the engine.
- Press and hold the "Unlock" button on the key fob for 10 seconds.
- While holding the "Unlock" button, press the "Lock" button three times.
- Release the "Unlock" button; the vehicle should respond with a confirmation sound.
