Transponder Chips
Transponder chips are likely to be found in cars that were manufactured within the last 20 years. This is a little plastic thing on the back of your key that contains an RFID (Radio Frequency Identification) chip with a unique code that is specific to your particular vehicle.
When 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 barrel that controls your ignition in your car. The computer system in the vehicle is then able to verify that the chip in the key's transponder is the correct one for your car.
This stops the vehicle from starting by hot-wiring or manipulating. The chip inside the key also confirms that you are the legal owner of the vehicle. This can help to reduce car theft.

When the transponder key is placed in the ignition barrel, a circuit within of the induction coil sends out a signal. The signal will then get received by the chip, causing it to send a signal back to the car. If the computer inside the car detects the signal as correct it will turn off the vehicle immobilizer so that the engine can start.
If the vehicle 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 siren. This feature is designed to discourage people from tampering with the vehicle. However, it is not an unbreakable security measure.

Key fobs communicate with each with the car via radio frequencies which are transmitted via an antenna that is located in the middle of the key. This communication is encrypted to prevent others from intercepting or replicating the signal.
Keyfobs can be programmed in different ways based on the model and brand of your car. You may be able to do it yourself, but most newer cars require that you visit a dealer or professional locksmith to program a replacement or additional fob.
When you press the button on your key fob it transmits a code to the car's radio that it is paired with. The receiver compares this information to the 'allowed' signals on the fob and either opens or locks the door. If the information doesn't match the signals, a chirping sound can be heard and the car isn't allowed to operate.
Once the car is paired with a specific fob, it will only accept signals from the device. As a result, other fobs won't be able to work with the vehicle, even though they appear similar. This ensures the security of the computer system in the car and prevents unauthorised key fobs from taking control over it.
Most newer car dealerships will only accept vehicles that have original fobs, or genuine replacements supplied by the manufacturer. It is because the only place that has the expertise to prepare the replacement fob is the service department of the dealer. However, some aftermarket fobs -- usually those for older models with less sophisticated systems can be programmed by consumers without the need of dealers.
