Transponder Chips Transponder chips are likely be found in vehicles manufactured within the past 20 years. It's a small piece of plastic inside the head of your key which contains a RFID (Radio Frequency Identification) chip with a unique code that is specific to your particular vehicle. The chip sends out a low-level radio signal when it is activated by an electromagnetic field. The signal is then received by a specific antenna that is attached to the ignition barrel. This allows the car's computer system to determine if the transponder chip that is in the key is the correct one for your particular car.

The circuit in the induction coil emits signals when the transponder is put into ignition barrel. The signal will then get received by the chip, causing it to transmit a signal back to the car. If the onboard car computer recognizes this signal as being the right one, it will shut down the vehicle's immobilizer and allow the engine to start. If the vehicle does not recognize the transponder signal as the correct one, it will stop the engine from running and will alert you by flashing its lights and sounding siren. This function is designed to discourage those who would attempt to alter the vehicle. However it isn't a foolproof measure of security.

The frequencies are transmitted through a small antenna located within the middle of the key. This communication is encrypted, which helps to keep others from stealing and re-transmitting the signal. Keyfobs can be programmed in various ways based on the model and make of your vehicle. You can sometimes do this yourself, but the majority of newer cars require that you visit an expert locksmith or dealer to program a replacement or a second fob. When you press the button on a key fob, the microchip transmits signals to the receiver in the car with which it is linked. The receiver compares the information with the 'allowed signals' stored in the key fob, and then locks or opens the car's door. If the information doesn't match the signals, the car will not be allowed to run. Once the car has been associated with a particular fob, it will only accept signals from that device. Other fobs will not work with the car, even if they appear similar. This safeguards the integrity of the computer system in the vehicle and stops unauthorised key fobs from taking control of it. Most newer car dealerships will only work with vehicles that have original fobs or genuine replacements sold by the manufacturer.
