Abstract
A vehicle security system with anti-robbery function which has a mainframe including a software stored in a CPU and preset code recorded in a permanent memory unit. A key receiving means is electrically connected to the mainframe and a contact-type relief key also provided with a corresponding code which must match the preset code in the permanent memory unit to start the engine of a vehicle. The key receiving means is provided with a button and at least one relay is housed in the mainframe. Once the button is pressed, the security system enters an anti-robbery mode, and after a preset period of time, the CPU will make the horn of the vehicle honk and the head light and direction indicating lights flash continuously. After the engine is stopped, the CPU uses the relay or relays to make the engine starting circuit inoperative so as to further control the power-on, engine starting, ignition and oil supply circuitries of the vehicle not to function, making the security system operated in a more secure and practical manner.
