Transponder Chips
If your car was built within the past 20 years, chances are it contains a transponder chip within of it. This is a little plastic piece on the back of your key that contains an RFID (Radio Frequency Identification) chip with a unique code for your specific vehicle.
The chip emits a low-level radio signal when it is activated by an electromagnetic field. This signal is then absorbed by a special antenna that is attached to the ignition barrel. This allows the computer in your vehicle system to verify that the transponder chip in the key is the correct one for your specific vehicle.

When the transponder key is inserted into the ignition barrel, a circuit within of the induction coil will send out an electrical signal. The signal will be received by the chip, causing it to transmit a signal back to the car. If the onboard car computer detects this signal as the correct one, it will shut down the vehicle's immobilizer and allow the engine to start.
If the vehicle doesn't recognize the transponder as a valid signal, it will not start the engine and will notify you via flashing lights and siren. This is designed to deter people from trying to hack into the vehicle, however it is not a foolproof security measure. A skilled and determined thief could still evade this system using a special device that detects the signal.

When you press a key fob's button, the microchip inside transmits an informational code to the car's receiver it is paired with. The receiver compared this information to the 'allowed' signals stored in the fob and then either opens or locks the door. If the information doesn't match the signals, the car will not be allowed to run.
After the car has been connected to a specific fob, it only accepts signals from the device. This means that other fobs will not work with the vehicle even if they have the same appearance. This protects the integrity of the computer system in the car and blocks unauthorised key fobs from taking control of it.
Most dealerships with newer cars will only work with cars that have original fobs, or genuine replacements supplied by the manufacturer. It is because the only place with the knowledge to create a replacement fob is in the service department of the dealer. However, some aftermarket fobs typically for older models that have less sophisticated systems -- can be programmed by consumers without the need for dealers.
