Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is off.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Replace Key Fob Battery

Use a small flathead screwdriver to gently pry open the key fob casing.
Remove the old battery (often CR2032) and replace it with a new one, ensuring correct polarity.
Reassemble the key fob casing and test the remote start function.

3. Inspect Security System

Reconnect the negative battery terminal.
Use the OBD-II scanner to check for any fault codes related to the anti-theft system.
If codes are present, follow diagnostic procedures for those specific codes.

4. Verify Remote Start Module

Locate the remote start module (usually found under the dash or near the steering column).
Check wiring connections to ensure they are secure and free from corrosion.
If damaged, replace the remote start module following manufacturer specifications.

5. Test Remote Start

Ensure the vehicle is in park and all doors are secured.
Press the remote start button on the key fob and observe if the vehicle starts.
If still inoperable, consult the vehicle’s service manual for further troubleshooting steps or consider professional assistance.
