Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, screwdriver set, and replacement fob battery if needed.
Ensure the vehicle is parked on a level surface and the ignition is off.

2. Check Key Fob Battery

Remove the key fob casing using a small screwdriver.
Replace the old battery with a new one (typically CR2032 or similar).
Reassemble the key fob and test the remote start function.

3. Inspect Vehicle Battery

Use a multimeter to check the voltage of the vehicle battery; it should be above 12.6 volts.
If the voltage is low, charge or replace the battery as necessary.

4. Verify Gear and Door Status

Confirm that the gear shift is in the "Park" position.
Check all doors to ensure they are fully closed, including the hood and trunk.

5. Fuse Inspection

Open the fuse box and locate the fuse for the remote start system.
Remove the fuse and inspect it for any signs of damage. Replace it if it is blown.

6. Check Security System

Make sure the vehicle’s security system is functioning correctly. If it is triggered or faulty, it may prevent remote start.
Reset the security system according to the vehicle’s manual if needed.
