Transponder Chips
Transponder chips can be found in cars manufactured within the past 20 years. This is the little plastic piece in the head of the car key that has an RFID (Radio Frequency ID) chip that has a unique code to your vehicle.
The chip emits an low-level radio signal once it is activated by an electromagnetic field. This signal then gets absorbed by the special antenna that is attached to the barrel that controls your ignition in your vehicle. This allows the computer in your vehicle system to determine if the transponder chip inside the key is the right one for your specific vehicle.
This prevents the vehicle from starting by hot-wiring or altering the key. The chip inside the key also confirms that you are the legitimate owner of the vehicle. This can reduce car theft.

A circuit within the induction coil emits an electrical signal when the transponder is put into an ignition barrel. The signal will be received by the chip and cause it to transmit a signal back to the car. If the onboard car computer recognizes this signal as being the correct one, it will disable the immobilizer on the vehicle and allow the engine to begin.
If the car does not recognize the transponder signal as being the proper one, it will keep the engine from starting and will notify you by flashing its lights and sounding siren. This feature is intended to discourage people from trying to alter the vehicle, however it's not a 100% security measure.

Key fobs communicate with each with the car via radio frequencies which are transmitted via an antenna that is located in the middle of the key. The signal is encrypted to prevent others from stealing or stealing the signal.
Keyfobs can be programmed in various ways based on the make and model of your vehicle. You may be able to do it yourself, however most modern cars require that you visit a dealer or professional locksmith to program a replacement or an additional fob.
When you press the button on your key fob the microchip inside sends a code to the car's receiver that it is paired with. The receiver then compares the data with the permitted signals stored on the key fob and then it opens or closes the car's door. If the information isn't in line an chirping sound is heard and the car isn't allowed to function.
When a car is connected with a particular fob, it will only receive signals from the device that is associated with it. As a result, other fobs won't work with the vehicle even if they have the same appearance. This ensures the security of the computer system that runs the car and blocks unauthorised key fobs from taking control over it.
Most newer car dealers will only work on cars with original fobs or genuine replacements that are offered by the manufacturer. This is because the process of creating an appropriate replacement fob requires technical and security expertise that is only available in the dealer service department. Some fobs from the aftermarket, especially those from older models that have less advanced systems, can be programmed without the need for a dealer.
