Solution

1. Preparation

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

2. Check Key Fob Battery

Remove the key fob cover using a small flathead screwdriver.
Replace the CR2450 battery with a new one, ensuring correct polarity.
Reassemble the key fob and test the remote start function.

3. Verify Remote Start Settings

Reconnect the battery terminal.
Start the vehicle normally and check the iDrive system settings.
Navigate to "Settings" > "Doors/Access" > "Remote Start" and ensure it is enabled.

4. Inspect Electrical Connections

Visually check all fuses related to the starting system: locate the fuse box (usually under the dashboard or in the engine bay).
Replace any blown fuses with the same amperage rating.
Inspect wiring harnesses for any signs of damage or corrosion.

5. Test Key Fob Signal Strength

Use a multimeter to measure the voltage output of the key fob while pressing the start button.
If the voltage is low (below 2.7V), replace the key fob.

6. Reset Anti-Theft System

If the vehicle's anti-theft system is triggering, follow these steps:
- Lock the vehicle using the key fob.
- Wait for 10-15 minutes.
- Unlock and try using the remote start again.
