Transponder Chips
Transponder chips are likely be found in cars manufactured in the last 20 years. This is a little plastic thing inside the head of your key which contains a RFID (Radio Frequency Identification) chip with a unique code for your particular vehicle.
When it is activated by an electro-magnetic field, the chip emits a low-level signal. This signal is then absorbed by the special antenna that is positioned around the barrel that controls your ignition in your car. The computer system in the vehicle is then able to verify that the transponder chip of the key is the right one for your car.
This is what prevents doing hot-wiring or altering the ignition system of your vehicle to start it. The chip inside the key also confirms that you are the genuine owner of the vehicle. This helps to reduce the risk of theft from your car.

A circuit inside the induction coil will emit a signal when the transponder is inserted into the ignition barrel. The signal will be received by the chip, causing it to send a signal back to the car. If the computer inside the car is able to recognize the signal as valid it will turn off the car keys cut and programmed immobilizer so that the engine can start.
If the car isn't able to recognize the transponder as a valid signal, it won't start the engine and alert you with flashing lights and siren. This feature is designed to discourage people from tampering with the vehicle. However it's not a foolproof measure of security. A skilled and committed thief might be able get around this system using a special device to intercept the signal.

Key fobs are able to communicate with each other and with the car through radio frequencies which are transmitted through a small antenna located in the center of the key. This communication is encrypted, which helps prevent others from intercepting and retransmitting the signal.
There are a few different ways to program a key fob depending on the model and make. You can sometimes do this yourself, however most modern vehicles require a dealer or professional locksmith to program a replacement or a second fob.
When you press a key fob's button, the microchip inside transmits an informational code to the car's radio that it is linked to. The receiver then compares this information with the 'allowed' signals stored inside the fob key programming, and either locks or opens the door. If the information isn't in line the signals, a chirping sound can be heard and the car isn't allowed to function.
After the car has been paired with a specific fob, it can only receive signals from that device. Other fobs will not work with the car, even if they appear like. This protects the integrity of the car's computer system and prevent unauthorized key fobs from gaining control of the vehicle.
The majority of newer dealers will only work on cars with original fobs or genuine replacements that are supplied by the manufacturer. The reason for this is that the only place with the experience to design the replacement fob is a dealer's service department. However, some fobs from the aftermarket typically for older models with less sophisticated systems -- can be programmed by consumers without the need of a dealership.
