Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the vehicle battery to prevent electrical shorts during repairs.
Tools Required:
- OBD-II scanner
- Screwdriver set
- Multimeter
- Wire connectors (if needed)

2. Key Fob Battery Replacement

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

3. Reset Security System

Reconnect the vehicle battery.
Insert the key into the ignition and turn it to the "On" position without starting the engine.
Wait for 10 seconds, then turn the key back to the "Off" position.
Repeat this process three times, ending in the "On" position to reset the security system.

4. Check Remote Start Module

Locate the remote start module in the engine bay or under the dashboard.
Inspect all connections to ensure they are secure and free from corrosion.
Use a multimeter to check the voltage at the module; it should read the vehicle's battery voltage.
If the module is faulty, replace it with a compatible replacement part.
