Transponder Chips
Transponder chips are likely to be found in cars that were manufactured within the last 20 years. It's a tiny piece of plastic on the back of your key that houses an RFID (Radio Frequency Identification) chip with a unique code that is specific to your particular vehicle.
When it is activated by an electromagnetic field the chip emits a low-frequency signal. This signal then gets taken up by the antenna that is attached to the ignition barrel of your vehicle. The computer system of the vehicle is then able to verify that the key's transponder chip is the right one for your vehicle.
This is the reason why doing hot-wiring or altering the ignition system of your vehicle to turn it on. The chip in the car key verifies that the owner is the person who owns the vehicle. This helps to prevent the possibility of theft from your vehicle.

When the transponder key is inserted in the ignition barrel, a circuit inside of the induction coil sends out the signal. The signal will then get taken up by the chip and cause it to send a signal back to the car. If the car's computer detects this signal as the right one, it will disable the vehicle's immobilizer and allow the engine to start.
If the vehicle doesn't 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 a siren. This system is designed to deter those who would attempt to alter the vehicle. However, it is not an unbreakable security measure. A skilled and determined criminal could still be able to escape this security system by using a special device to take over the signal.

When you press the button on your key fob, the microchip inside transmits a code to the car's radio that it is paired with. The receiver then compares this information with the signals that are allowed on the fob and either opens or closes the door. If the information doesn't match, the car will not be allowed to operate.
After the car has been paired with a specific fob, it will only accept signals from that device. Other fobs won't work with the car, despite the fact that they look identical. This helps to protect the integrity of the vehicle's computer system and to prevent the use of unauthorized key fobs to gain control of the vehicle.
The majority of car dealers who are newer will only work on a car with original fobs or genuine replacements offered by the manufacturer.

Some fobs from the aftermarket, especially those for older models that have less sophisticated systems can be programmed with out the need for a dealer.
