Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, fuse puller, screwdriver set.
Ensure the vehicle is parked on a flat surface and the ignition is turned off.

2. Key Fob Battery Replacement

Remove the key fob cover using a small screwdriver.
Take out the old battery and replace it with a new battery (typically CR2032).
Reassemble the key fob and test the remote start function.

3. Hood Switch Inspection

Locate the hood switch, usually positioned near the front of the engine bay.
Inspect the switch for damage or corrosion.
If faulty, replace the hood switch with a new one. Ensure it clicks properly when the hood is closed.

4. Fuse Inspection

Locate the fuse box, typically found under the dashboard or in the engine compartment.
Identify and remove the fuse related to the remote start system (check the fuse diagram).
Inspect the fuse for continuity using a multimeter; replace if blown.
Reinsert the new or functional fuse securely.

5. Battery Voltage Check

Use a multimeter to check the vehicle battery voltage.
Ensure it reads above 12.4 volts; if it’s lower, charge or replace the battery as needed.
