An anti-hijack security system which automatically protects the vehicle with anti-hijack after the ignition has been turned off for a predetermined long period of time or after the ignition has been turned off and a door has been opened and closed for a predetermined short period of time. Thus, ensuring the owner to have anti-hijack protection when he returns to his vehicle. The anti-hijack protection system also makes sure that, once triggered, it will perform the anti-hijack trigger sequence even if a door sensing device is damaged or if a door is not closed properly. The system also makes sure that once anti-hijack trigger sequence is in it's last few stages, it cannot be disarmed by simply pressing the arm/disarm switch but can only be disarmed by entering a security code. |
