- If the voltage is below 12.4 volts, proceed to recharge or replace the battery.
Clean and Tighten Battery Connections
- Remove any corrosion using a wire brush on the terminals.
- Ensure the connections are tight and secure.
Replace 12V Battery (if necessary)
- Remove the battery hold-down bracket using a socket set.
- Disconnect the negative terminal first, then the positive terminal.
- Replace with a new battery, connecting the positive terminal first, followed by the negative terminal.
- Reinstall the battery hold-down bracket.

3. Key Fob and Electrical System Check

Check Key Fob Battery
- Open the key fob and replace the battery if it is low or dead.
- Test the fob by pressing the unlock button and attempting to start the vehicle.
Inspect Fuses
