Transponder Chips
If your car is made in the last 20 years, chances are it has a transponder inside of it. It's a tiny 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.
When it is activated by an electro-magnetic field, the chip emits a low-frequency signal. The signal is absorbed by a special antenna that is attached to the ignition barrel. This allows the computer in your vehicle system to determine if the transponder chip inside the key is the right one for the car you have.

When the transponder key is placed in the ignition barrel, a circuit inside of the induction coil will send out the signal. The signal will be received by the chip and cause it to transmit a signal to the car. If the onboard car computer detects this signal as the right one, it will shut down the vehicle immobilizer and allow the engine to begin.
If the vehicle doesn't recognize the transponder signal as being the proper one, it will keep the engine from running and will notify you by flashing its lights and sounding an alarm. This feature is designed to discourage people from attempting to tamper with the vehicle, however it isn't a foolproof security measure. A determined and skilled thief could still bypass this system with a specially designed device that blocks the signal.

When you hit the button on a key fob, the microchip inside transmits an encoded code to the car's receiver it is paired with. The receiver compares this information with the 'allowed' signals on the fob and either opens or locks the door. If the data does not match the fob's information, the car won't be allowed to drive.
Once the car is connected to a specific fob, it will only accept signals from the device. Other fobs will not work with the car, even though they look identical. This protects the integrity of the computer system in the vehicle and stops the use of unauthorized key fobs to gain control over it.

The majority of newer dealers will only work on cars with original fobs or genuine replacements that are supplied by the manufacturer.
