Modern cars have immobiliser systems that are state-of-the-art. Advances in immobiliser technology have made it impossible for thieves to hot-wire or get around a car's immobiliser system to start the engine. Since 1997, almost every car made in the world has had a cutting-edge immobiliser system that is always getting better and making the car safer.
Even though each vehicle immobiliser system is a little different from the others, they all have something in common: a transponder chip. A tiny RFID (Radio-frequency identification) chip called a "transponder" stores a code that only works with that particular chip. Transponder chips don't need batteries to work. Instead, a tiny copper coil inside the chip acts as an antenna and gets a voltage from the magnetic field created by an antenna near the car's ignition. When you turn on your car, the code from the transponder chip on the head of the key is read by the antenna.
If the code on the transponder chip is the same as the code in the engine or immobiliser ECU, the car will start. If the code doesn't match, the car won't start. The staff at need car keys assists people all over Australia.
