Help! My car won’t start.

[Sparbrook]

My IS300 sport 2018 wont start. The key fob and battery are fine. The fan comes on but nothing else. And these messages pop up. The car does not even try to start, no ignition at all. Appreciate any thoughts

1. Battery Voltage: Ensure that the 12V battery voltage is sufficient. A low battery can prevent the engine from starting. You might want to check the battery’s charge level or have it tested.

2. Smart Key Battery: While you mentioned the key fob and battery are fine, it’s worth double-checking the Smart Key battery. If it’s weak, it could cause issues. There’s a mechanical key within the Smart Key that can open the driver’s door. Once inside, hold the Smart Key next to the START button and depress it.

3. Engine Immobilizer: Sometimes, an issue with the engine immobilizer system can prevent the car from starting. If the engine doesn’t crank at all, this could be a possibility.

4. Starter Motor: If the engine doesn’t even attempt to start, the starter motor might be faulty. A professional inspection is recommended.

5. Ignition Switch: Faulty ignition switches can also cause no-start issues. Have a mechanic check this component.

6. Diagnostic Scan: Consider getting a diagnostic scan done at an authorized dealer. It can reveal any error codes and help pinpoint the issue.

Try #2, first. If no luck, I would have the battery checked, next. Sometimes when the battery is weak, a message that makes no sense will illuminate. Ours tells us to place the shifter in Park. I know from experience that if that happens, the battery needs to be replaced.
