The chip is a microcircuit which transmits a radio frequency signal when the key is placed into the ignition. The car detects the signal, and starts the engine only if it matches the original one that was programmed in the vehicle. The vehicle is also programmed to stop if it detects an invalid frequency. This makes it harder for thieves who aren't experienced to wire a vehicle hot and then turn it on.
A circuit board that has an induction coil that connects the chip to the key. When the key is placed in the ignition, a magnetic field is generated around the transponder. This creates a signal that is taken up by the coil, which transmits it to the key's identification number.
