If your car was built within the last 20 years, it is likely that it has a transponder inside of it. It's a small plastic thing inside the head of your key that houses a RFID (Radio Frequency Identification) chip with a unique code that is specific to your specific vehicle.
The chip emits an low-level radio signal once it is activated by an electromagnetic field. This signal then gets amplified by the specific antenna that is positioned around the barrel that controls your ignition in your vehicle. The computer system in the vehicle will then confirm that the transponder chip of the key is the right one for your car.
This is what prevents from modifying or hot-wiring the ignition system of the vehicle to start it. The chip in the car key ensures that the owner is the one who owns the vehicle. This helps to reduce the risk of theft from your car.

The circuit in the induction coil will emit signals when the transponder is inserted into an ignition barrel. The signal is received by the chip which then transmits a signal to the vehicle. If the computer on the car detects this signal as the correct one, it will turn off the vehicle's immobilizer and allow the engine to start.
If the vehicle doesn't recognize the transponder signal as the right one, it will keep the engine from running and will notify you by flashing its lights and sounding an alarm. This feature is designed to deter people from trying to alter the vehicle, however it isn't a foolproof security measure. A skilled and determined thief could still be able to bypass this system by using a special device to intercept the signal.

Key Fobs
Key fobs today can offer more than locking and unlock doors. They can also turn on the vehicle remotely, make chirping noises to aid in finding cars, or turn on the heated steering wheel. These additional features can make it difficult to locate your car keys.
Key fobs use radio frequencies to communicate with one another and with the car. The frequencies are transmitted via a small antenna that is located inside the middle of the key. The signal is encrypted to prevent others from intercepting or replicating the signal.
You can program a keyfob in a variety of ways depending on the make and model of your vehicle. Certain cars let you do it yourself. However, the majority of modern models require you to visit an expert locksmith or dealer in order for them program a replacement key fob or additional one.
When you press the button on your key fob, the microchip inside transmits a code to the car's receiver it is linked to. The receiver then compares the data with the 'allowed signals' that are stored on the key fob and then opens or locks the car's doors. If the information isn't in line the signals, a chirping sound can be heard and the car isn't able to function.
Once the car is paired with a particular fob, it will only receive signals from the device that is associated with it. Other fobs will not work with the car, even if they appear similar. This protects the integrity of the computer system that runs the car and blocks unauthorised key fobs from taking control over it.
Most dealerships with newer cars will only deal with cars that have original fobs or genuine replacements supplied by the manufacturer. The reason for this is that the only place with the expertise to prepare the replacement fob is a dealer's service department. However, some fobs from the aftermarket that are typically designed for older models with less sophisticated systems -- can be programmed by consumers without the need for a dealership.
