Understanding Your Ford Focus Anti-Theft System

- Flashing Security Light: A rapidly flashing security light on your dashboard is a telltale sign of an activated anti-theft system.
- Engine Cranks but Won’t Start: If your engine cranks but refuses to start, it could be due to the anti-theft system preventing ignition.
