When it is activated by an electro-magnetic field the chip emits a low level signal. The signal is then amplified by the specific antenna that is attached to the ignition barrel of your vehicle. This allows the computer in your vehicle system to determine if the transponder chip that is in the key is the correct one for your particular car.

The circuit in the induction coil emits an electrical signal when the transponder is inserted into the ignition barrel. The signal will then get absorbed by the chip, causing it to transmit a signal to the car. If the computer on the car detects this signal as the right one, it will turn off the vehicle immobilizer and allow the engine to begin.

If the car does not recognize the transponder signal as the right one, it will keep the engine from running and will alert you by flashing its lights and sounding an alarm.

The receiver then compares the data with the permitted signals stored in the key fob and then it opens or closes the car's doors. If the information doesn't match the signals, a chirping sound can be heard and the car isn't permitted to operate.

Once the car is linked with a specific fob it will only accept signals from the device that is associated with it. This means that other fobs will not work with the vehicle even if they have the same appearance. This safeguards the integrity of the computer system of the vehicle and stops unauthorised key fobs from taking control over it.

Some fobs from the aftermarket, especially those from older models that have less advanced systems can be programmed without the need for a dealership.
