Locate the remote start antenna, often mounted near the windshield.
Visually inspect the wiring for frays or disconnections.
Reconnect any loose wires and secure the antenna properly.

With the negative battery terminal still disconnected, wait for 10 minutes to reset the vehicle's electronics.
Reconnect the negative battery terminal and check if remote start function is restored.

3. Turn the ignition off and remove the key.
4. Test the remote start function again.
