The chip emits an unintentional radio signal when it is activated by an electromagnetic field. The signal is then amplified by the specific antenna that is positioned around the ignition barrel of your car. The computer system in the vehicle will then confirm that the key's transponder chip is the correct one for your car.

When the transponder key is inserted into the ignition barrel, a circuit inside of the induction coil will send out an electrical signal. The signal is absorbed by the chip, which sends a signal to the vehicle. If the computer onboard the car recognizes the signal as correct it will turn off the car immobilizer to allow the engine start.
