The chip sends out a low-level radio signal when it is activated by an electromagnetic field.

When the transponder key is inserted into the ignition barrel, a circuit within of the induction coil will send out a signal. The signal will then get absorbed by the chip, causing it to transmit a signal to the car. If the car's computer recognizes this signal as the correct one, it will shut down the vehicle immobilizer and allow the engine to begin.
If the car does not recognize the transponder signal as being the right one, it will prevent the engine from starting and will alert you by flashing its lights and sounding siren. This feature is intended to discourage people from trying to alter the vehicle, but it isn't a foolproof security measure. A skilled and determined thief could still bypass this system by using a specific device that blocks the signal.
