Transponder Chips
If your car was built within the past 20 years, then it has a transponder inside of it. This is a little plastic piece on the back of your key that houses an RFID (Radio Frequency Identification) chip with an individual code for the specific vehicle you own.
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 will then confirm that the transponder chip of the key is the correct one for your car.
This is what stops from modifying or hot-wiring the vehicle's ignition system to turn it on. The chip in the key also verifies 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 emits signals when the transponder is put into the ignition barrel. The signal is absorbed by the chip, which then transmits a signal the vehicle. If the computer onboard the car detects the signal as valid it will turn off the vehicle immobilizer to allow the engine start.
If the car isn't able to recognize the transponder as a valid signal, it won't start the engine and will notify you via flashing lights and siren. This system is designed to deter individuals from tampering with the vehicle. However it isn't an unbreakable security measure. A skilled and determined criminal may still be able to get around this system using a special device to detect the signal.

Key Fobs

Key fobs make use of radio frequencies to connect with one another and the car. These frequencies are sent by a small antenna inside the middle of the key. This signal is encrypted to stop others from intercepting or replicating the signal.
Keyfobs can be programmed in a variety of ways depending on the make and model of your car. Certain models allow you to do this yourself. However, the majority of modern models require you to visit an expert locksmith or dealer to program a new key fob, or an alternative one.
When you press a key fob's button the microchip inside sends a code to the car's receiver it is linked to. The receiver compared this information to the 'allowed' signals stored in the fob and then either opens or locks the door. If the information does not match, the car will not be allowed to run.
When a car is connected with a particular fob, it will only accept signals from the device that is associated with it. Other fobs will not work with the car, even though they appear identical. This safeguards the integrity of the computer system of the car and blocks the use of unauthorized key fobs to gain control of it.
Most newer car dealerships will only accept vehicles that have original fobs or genuine replacements offered by the manufacturer. It is because the only place with the knowledge to create the replacement fob is a dealer's service department. However, some fobs from the aftermarket that are typically designed for older models that have less sophisticated systems -- can be programmed by consumers without the need for a dealership.
