[LaHaley]

The Passat's anti-theft system primarily involves engine immobilization, meaning the key contains an anti-theft code. When starting the vehicle, the engine control unit first verifies the key code. Only upon a successful match will the engine receive the signal to start, thereby reducing the likelihood of theft. This differs from a standard car alarm. Additional Information: Car Anti-Theft Devices: A car anti-theft device is installed in a vehicle to increase the difficulty and time required for theft, acting as a guardian for the car. By integrating the anti-theft device with the vehicle's electrical system, it prevents unauthorized access, protects the vehicle, and enables various anti-theft functions. With advancements in technology, various types of anti-theft devices have been developed to counter increasingly sophisticated theft methods. These devices can be categorized into four main types: mechanical, chip-based, electronic, and network-based.
