Transponder Chips
If your car is made in the past 20 years, it is likely that it has a transponder inside of it. It's the small plastic piece in the head of your car key that houses an RFID (Radio Frequency ID) chip with a unique code for the vehicle you own.
The chip emits a low-level radio signal when it is activated by an electromagnetic field. The signal is absorbed by a special antenna attached to the ignition barrel. The computer system of the vehicle will then confirm that the transponder chip of the key is the right one for your car.
This is what prevents hot-wiring or tampering with the ignition system of your vehicle to turn it on. The chip in the key also verifies that you are the genuine owner of the vehicle. This helps to reduce the risk of theft from your car.

The circuit in the induction coil will emit a signal when the transponder is put into ignition barrel. The signal will be taken up by the chip, causing it to transmit a signal to the car. If the computer in the car detects the signal as correct it will turn off the vehicle immobilizer so that the engine can start.
If the vehicle doesn't recognize the transponder as a valid signal, it won't start the engine and will warn you with flashing lights and siren. This system is designed to deter people from tampering with the vehicle. However it isn't a foolproof measure of security. A skilled and skilled criminal could still evade this system by using a specific device that detects the signal.

Key fobs make use of radio frequencies to communicate with one another and the car. These frequencies are transmitted via a small antenna that is located in the middle of the key. The transmission is encrypted, which helps to keep others from stealing and replicating the signal.
Keyfobs can be programmed in different ways based on the make and model of your car. You may be able to do it yourself, however most modern automobiles require a locksmith shop or a professional to program a replacement or a second fob.
When you press the button on a key fob the microchip sends a signal to the receiver in the vehicle with which it is linked. The receiver compares the information with the permitted signals stored in the key fob, and then it opens or closes the car's door. If the data doesn't match, a chirping sound is heard and the car isn't able to function.
Once the car is linked with a specific fob it will only receive signals from the device that is associated with it. As a result, other fobs won't be able to work with the vehicle even though they look the same. This ensures the security of the computer system that runs the vehicle and stops the use of unauthorized key fobs to gain control over it.
Most newer car dealers will only work on cars with original fobs or genuine replacements offered by the manufacturer. This is because preparing a replacement fob requires technological and security skills that is only available in the dealer service department. Certain aftermarket fobs, typically those from older models that have less sophisticated systems can be programmed without the need for a dealer.
