The car also shuts down if the frequency is not valid. This makes it difficult for thieves who aren't experienced to wire a vehicle hot and then turn it on.
The key and the chip are connected by a circuit board that includes an induction coil. When the key is placed in the ignition, it creates a magnetic field around the transponder. This creates a signal that gets taken up by the coil, which then transmits it to key's identification number.
