Solution

1. Preparation

Gather necessary tools: OBD-II scanner, multimeter, fuse puller, and a battery tester.
Ensure the vehicle is parked safely and the ignition is off.

2. Key Fob Battery Replacement

Open the key fob casing using a small flathead screwdriver.
Remove the old battery and replace it with a new CR2032 battery, ensuring correct polarity.
Close the key fob casing securely.

3. Fuse Inspection

Locate the fuse box, typically found under the dashboard or in the engine compartment.
Use a fuse puller to remove the fuses related to the remote start (refer to the owner's manual for specific fuse locations).
Inspect each fuse; replace any blown fuses with new ones of the same amperage.

4. Functionality Check of Remote Start

Reconnect the battery and verify the vehicle's battery voltage using a multimeter.
Attempt to engage the remote start feature again using the key fob.
If the remote start still fails, proceed to reset the vehicle's onboard computer by disconnecting the battery for 10 minutes, then reconnecting it.

5. Security System Bypass

If there's a security system warning, ensure all doors, trunk, and hood are closed properly.
If issues persist, consult the vehicle's manual for instructions on bypassing or resetting the security system.
