Solution

1. Preparation

Carefully remove the old battery and replace it with a new CR2032 battery, ensuring correct polarity (+/-).
Reassemble the key fob and test the remote start function.

3. Inspect Vehicle Battery

Use a multimeter to check the vehicle battery voltage.
If the voltage is low (below 12.4 volts), charge the battery or replace it if it fails to hold a charge.
Ensure all battery terminals are clean and securely connected.

4. Verify Remote Start Conditions

Check that all doors, trunk, and hood are securely closed.
Ensure that the vehicle is in "Park" (automatic transmission) or "Neutral" (manual transmission).
Attempt to use the remote start feature again.

5. Update Vehicle Firmware

Connect the OBD-II scanner to the vehicle's diagnostic port.
Check for any firmware updates available for the vehicle.
Follow manufacturer instructions to update if needed.
