Transponder Chips
If your car was built within the last 20 years, it is likely that it has a transponder inside of it. This is a little piece of plastic on the back of your key that houses a RFID (Radio Frequency Identification) chip with an individual code for your particular vehicle.
The chip sends out a low-level radio signal when it is activated by an electromagnetic field. This signal is then taken up by the antenna that is fitted around the ignition barrel of 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.

When the transponder key is placed in the ignition barrel, a circuit within of the induction coil sends out the signal. The signal is received by the chip which sends a signal to the vehicle. If the computer inside the car recognizes the signal as being correct it will turn off the vehicle immobilizer, allowing the engine to 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 an alarm. This is designed to discourage people from attempting to alter the vehicle, however it isn't a foolproof security measure.

When you press the button on a key fob, the microchip transmits a signal to the receiver in the vehicle with which it is linked. The receiver compared this information with the 'allowed' signals inside the fob, and either locks or opens the door. If the information doesn't match the fob's information, the car won't be allowed to run.
Once the car has been connected to a specific fob, it will only accept signals from the device. Other fobs will not work with the car, even if they look like. automotive key programming protects the integrity of the car's computer system and to prevent unauthorised key fobs from taking control over the vehicle.
