Transponder Chips
Transponder chips can be found in cars manufactured within the last 20 years. This is a little piece of plastic in the head of your key which contains an RFID (Radio Frequency Identification) chip with a unique code that is specific to the specific vehicle you own.
When it is activated by an electro-magnetic field the chip emits a low-level signal. The signal is then taken up by the antenna that is attached to the barrel that controls your ignition in your car. This allows the computer in your vehicle system to determine if the transponder chip inside the key is the right one for your particular car.
This prevents the vehicle from being started by hot-wiring, or by tampering. The chip inside the key also confirms that you are the legal owner of the vehicle. This helps to prevent car theft.

When the transponder key is inserted into the ignition barrel, a circuit inside of the induction coil will send out the signal. The signal will then get taken up by the chip and cause it to transmit a signal back to the car. If the onboard car computer detects this signal as the right one, it will disable the vehicle immobilizer and allow the engine to start.
If the vehicle does not recognize the transponder signal as the proper one, it will keep the engine from running and will alert you by flashing its lights and sounding a siren. This system is designed to deter individuals from tampering with the vehicle. However it isn't a foolproof measure of security. A skilled and skilled criminal could still bypass this system with a specially designed device that blocks the signal.

If the information isn't in line the signals, a chirping sound can be heard and the car isn't permitted to operate.
