The chip sends out an unintentional radio signal when it is activated by an electromagnetic field. The signal is taken up by an antenna that is attached to the ignition barrel. The computer system in the vehicle is then able to verify that the key's transponder chip is the correct one for your car.

If the computer in the car recognizes the signal as correct it will turn off the car immobilizer so that the engine can start.
If the car does not recognize the transponder signal as being the proper one, it will prevent the engine from starting and will alert you by flashing its lights and sounding an alarm. This is designed to discourage people from trying to alter the vehicle, but it isn't a foolproof security measure.

If the data does not match the signals, the car will not be allowed to drive.
Once the car is connected to a specific fob, it only accepts signals from the device. This means that other fobs will not work with the vehicle, even though they have the same appearance. This helps to protect the integrity of the car's computer system and prevent the use of unauthorized key fobs to gain control of the vehicle.
