Solution

1. Preparation

Gather tools: small screwdriver, multimeter, and a flat surface to work on.
Ensure the vehicle is in a safe location and that you have access to the key fob.

2. Inspect Battery Installation

Remove the key fob cover using the small screwdriver.
Carefully take out the battery and inspect the contacts for debris or corrosion.
Reinsert the new battery, ensuring it is oriented correctly (positive side facing up).

3. Test Battery Voltage

Set the multimeter to measure DC voltage.
Place the probes on the battery terminals to check for a voltage reading (should be close to the rated voltage, usually 3V for CR2032 batteries).
If the voltage is low, replace the battery with a new one.

4. Reprogram Key Fob

Sit inside the vehicle with all doors closed.
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 about 5 seconds.
Turn the ignition off and remove the key; then test the key fob functionality.

5. Check Receiver Functionality

If the key fob still does not work, check the vehicle's keyless entry receiver.
Inspect the wiring and connections to ensure they are intact.
If necessary, consult the vehicle’s service manual for further troubleshooting on the receiver.
