The car is able to detect the signal and starts the engine only if the signal matches the original one that was programmed in the vehicle. The car is also programmed so that it will stop when it detects an incorrect frequency. This makes it harder for thieves who aren't experienced to connect a vehicle to a hot wire and then turn it on.
A circuit board equipped with an induction coil connects the key to the chip. When the key is placed in the ignition it creates an electromagnetic field around the transponder. This creates a signal that is amplified by the coil which sends it to the key's identification number. The ID number of the key is then sent back to the vehicle and if it matches the engine will start.
