If your car was manufactured in the last 20 years, then it has a transponder inside of it. It's the small plastic piece in the head of your car key that contains an RFID (Radio Frequency ID) chip with a unique code for the vehicle you own.
When it is activated by an electromagnetic field, the chip emits a low-level signal. The signal is taken up by an antenna that is attached to the barrel of ignition. This allows the computer in your vehicle system to confirm that the transponder chip in the key is the right one for your specific vehicle.

A circuit inside the induction coil will emit signals when the transponder is put into an ignition barrel. The signal will be absorbed by the chip and cause it to transmit a signal back to the car. If the computer onboard the car detects the signal as being correct it will turn off the car immobilizer to allow the engine start.
If the car does not recognize the transponder signal as the right one, it will stop the engine from running and will notify you by flashing its lights and sounding a siren. This is designed to discourage people from trying to tamper with the vehicle, however it's not a 100% security measure. A determined and skilled thief could still bypass this system by using a specific device that intercepts the signal.

Key fobs utilize radio frequencies to communicate with each other and with the car. The frequencies are transmitted by a small antenna in the middle of the key. This communication is encrypted, which helps to prevent others from intercepting and replicating the signal.
Keyfobs can be programmed in different ways based on the model and make of your vehicle. Certain models allow you to do this yourself. However, the majority of modern models require you to visit a professional locksmith or dealer in order to program a new key fob or an additional one.
When you press the button on a key fob the microchip transmits an indication to the receiver in the vehicle with which it is linked. The receiver compared the information with the permitted signals stored in the key fob and then opens or locks the car door. If the data doesn't match an chirping sound is heard and the car isn't permitted to function.
Once the car has been connected to a specific fob, it will only accept signals from that device. Other fobs will not work with the car, even if they look identical. This ensures the security of the computer system in the vehicle and stops unauthorized key fobs gaining control over it.
The majority of car dealers who are newer will only work on cars with original fobs or genuine replacements that are supplied by the manufacturer. This is because the process of creating a replacement fob requires technological and security expertise which can only be obtained in the dealer service department. Some aftermarket fobs, usually those from older models that have less advanced systems can be programmed with out the need for a dealer.
