When activated by an electro-magnetic field the chip emits a low level signal. This signal is then absorbed by a special antenna that is attached to the ignition barrel. The computer system of the vehicle will then confirm that the chip in the key's transponder is the correct one for your vehicle.

When the transponder key is inserted into the ignition barrel, a circuit inside of the induction coil sends out the signal. The signal is absorbed by the chip, which then transmits a signal the vehicle. If the onboard car computer recognizes this signal as being the correct one, it will disable the vehicle's immobilizer and allow the engine to begin.
