The chip sends out an low-level radio signal once it is activated by an electromagnetic field. The signal is then taken up by an antenna that is attached to the ignition barrel. The computer system in the vehicle is then able to verify that the key's transponder chip is the right one for your car.

A circuit within the induction coil will emit an electrical signal when the transponder is put into the ignition barrel. The signal will then get received by the chip and cause it to send a signal back to the car key programmed. If the car's computer recognizes this signal as being the right one, it will disable the vehicle's immobilizer and allow the engine to begin.
