What does the car lock indicator mean?

[Lukas]

When the car dashboard displays an icon of a car with a lock, it indicates the engine immobilizer system. The engine immobilizer prevents the engine from starting unless a system-recognized key is used, thereby deterring vehicle theft. Additional information: How anti-theft technology works: Most modern vehicle control systems are electronically managed, including the fuel injection system, ignition system, and braking system. Engine immobilizer technology essentially keeps these systems deactivated or inoperative until proper unlocking occurs. Even if someone forcibly engages the starter motor, the EFI system won't inject fuel and the ignition system remains inactive, making the vehicle impossible to start.
