The chip emits an low-level radio signal once it is activated by an electromagnetic field. The signal is then taken up by the antenna that is attached to the ignition barrel of your car. This allows the computer in your vehicle system to verify that the transponder chip that is in the key is the correct one for your particular car.

When the transponder key is inserted in the ignition barrel, a circuit within of the induction coil sends out an electrical signal. The signal is taken up by the chip, which then transmits a signal the vehicle. If the computer on the car detects this signal as the right one, it will turn off the immobilizer on the vehicle and allow the engine to begin.

If the data does not match the signals, the car will not be allowed to operate.

Once the car has been paired with a specific fob, it can only receive signals from that device. Other fobs won't work with the car, even though they look identical. This ensures the security of the computer system in the car and prevents the use of unauthorized key fobs to gain control over it.
