Transponder Chips
Transponder chips can be found in cars manufactured within the last 20 years. It's a tiny piece of plastic inside the head of your key that houses a RFID (Radio Frequency Identification) chip with a unique code that is specific to the specific vehicle you own.
The chip emits an unintentional radio signal when it is activated by an electromagnetic field. This signal then gets taken up by the antenna that is attached to the barrel that controls your ignition in your vehicle. The computer system in the vehicle can then verify that the key's transponder chip is the correct one for your car.

When the transponder key is inserted into the ignition barrel, a circuit within of the induction coil sends out a signal. The signal will be absorbed by the chip and cause it to transmit a signal to the car. If the car's computer recognizes this signal as being the right one, it will disable the vehicle immobilizer and allow the engine to begin.
If the vehicle doesn't recognize the transponder signal as being the correct one, it will keep the engine from starting and will notify you by flashing its lights and sounding siren. This feature is intended to discourage people from trying to hack into the vehicle, however it isn't a foolproof security measure.

Key fobs use radio frequencies to communicate with each other and the car. These frequencies are transmitted by a small antenna within the middle of the key. The transmission is encrypted, which helps to prevent others from intercepting and replicating the signal.
There are many ways to program a key fob, based on your vehicle's model and make. Certain models allow you to do it yourself. However, most newer models require you to visit a professional locksmith or dealer in order for them program a replacement key fob, or an alternative one.
When you press the button on a key fob the microchip sends signals to the receiver in the vehicle with which it is linked. The receiver compared this information with the 'allowed' signals stored inside the fob, and either locks or opens the door. If the data does not match the fob's information, the car won't be allowed to run.
Once the car is associated with a particular fob, it only accepts signals from the device. As a result, other fobs will not work with the vehicle even if they appear similar. This is to safeguard the integrity of the vehicle's computer system, and also to stop the use of unauthorized key fobs to gain control of the vehicle.
Most dealerships with newer cars will only work with cars with original fobs, or genuine replacements offered by the manufacturer. This is due to the fact that preparing the replacement fob is a process that requires technological and security skills which can only be obtained in the dealer service department. However, some fobs from the aftermarket that are typically designed for older models that have less sophisticated systems -- can be programmed by the consumer without the need for dealers.
