Transponder Chips
If your car is made within the last 20 years, chances are it has a transponder inside of it. It's a small piece of plastic inside the head of your key that houses a RFID (Radio Frequency Identification) chip with an individual code for your specific vehicle.
When it is activated by an electromagnetic field, the chip emits a low-level signal. The signal is absorbed by a special antenna attached to the barrel of ignition. The computer system of the vehicle is then able to verify that the chip in the key's transponder is the correct one for your vehicle.

The signal will be received by the chip and cause it to send a signal back to the car. If the computer onboard the car recognizes the signal as valid it will turn off the car key reprogramming immobilizer to allow the engine start.
If the car doesn't recognize the transponder as a valid signal, it will not start the engine, and will notify you via flashing lights and a siren.

Keyfobs can be programmed in a variety of ways depending on the model and brand of your car. Some cars allow you to do this yourself. However, most newer models require you to visit a professional locksmith or dealer to program a new key fob, or an alternative one.
When you press the button on a key fob, the microchip transmits an indication to the receiver inside the car that it is paired. The receiver then compares the data with the 'allowed signals' that are stored in the key fob and then locks or opens the car's doors. If the data does not match the signals, the car will not be allowed to operate.
Once the car is linked with a specific fob it will only accept signals from that specific device. Other fobs won't work with the car, even though they look similar. This protects the integrity of the computer system that runs the car and blocks the use of unauthorized key fobs to gain control of it.
Most dealerships with newer cars will only deal with cars that have original fobs or genuine replacements supplied by the manufacturer. This is because the only place that has the experience to design an appropriate replacement fob is the service department of the dealer. However, some aftermarket fobs -- usually those for older models that have less sophisticated systems can be programmed by customers without the need for a dealership.
