The chip emits a low-level radio signal when it is activated by an electromagnetic field. This signal then gets amplified by the specific antenna that is fitted around the ignition barrel of your vehicle. This allows the computer in your vehicle system to confirm that the transponder chip inside the key is the correct one for your particular car.

When the transponder key is placed in the ignition barrel, a circuit inside of the induction coil will send out an electrical signal. The signal will be received by the chip and cause it to transmit a signal to the car. If the computer on the car detects this signal as the correct one, it will disable the vehicle's immobilizer and allow the engine to begin.

Once the car has been connected to a specific fob, it only accepts signals from the device. Other fobs will not work with the car, even if they look identical.
