Solution

1. Preparation

Gather necessary tools: OBD-II scanner, multimeter, screwdriver set, and replacement key fob battery.
Ensure the vehicle is parked in a safe location with the engine off.
Disconnect the battery to prevent any electrical short circuits during repairs.

2. Key Fob Battery Replacement

Sub-step 1: Remove the key fob cover using a small flathead screwdriver.
Sub-step 2: Take out the old battery (usually CR2032) and replace it with a new one, ensuring correct polarity.
Sub-step 3: Reassemble the key fob and test the remote start function again.

3. Inspect Remote Start Wiring

Sub-step 1: Remove any panels covering the remote start module (if applicable).
Sub-step 2: Inspect all connections for corrosion or damage; repair or replace as necessary.
Sub-step 3: Use a multimeter to check for continuity and proper voltage at the remote start module.

4. Check for Fault Codes

Sub-step 1: Connect the OBD-II scanner to the vehicle's port.
Sub-step 2: Retrieve and record any fault codes that may indicate issues with the remote start or immobilizer systems.
Sub-step 3: Clear the codes and test the remote start again to see if any codes reappear.

5. Verify Safety Features

Sub-step 1: Ensure the gear selector is in the "Park" position.
Sub-step 2: Check that the hood is fully closed, as many vehicles have a hood switch that disables remote start.
Sub-step 3: Attempt to start the vehicle remotely again.
