Transponder Chips Transponder chips are likely be found in cars that were manufactured within the past 20 years.

The chip emits an unintentional radio signal when it is activated by an electromagnetic field. This signal then gets taken up by the antenna that is attached to the barrel that controls your ignition in your vehicle. This allows the car's computer 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 sends out an electrical signal. The signal will then get absorbed by the chip and cause it to transmit a signal to the car. If the onboard car computer recognizes this signal as being the right one, it will disable the vehicle's immobilizer and allow the engine to start. If the vehicle does not recognize the transponder signal as being the proper one, it will keep the engine from running and will alert you by flashing its lights and sounding an alarm. This feature is designed to deter people from trying to alter the vehicle, but it isn't a foolproof security measure.

You may be able to do it yourself, but most newer automobiles require an expert locksmith or dealer to program a replacement or an additional fob. When you press the button on a key fob the microchip transmits a signal to the receiver in the vehicle with which it is paired. The receiver compared this information to the signals that are allowed on the fob and either locks or opens the door. If the information doesn't match the fob's information, the car won't be allowed to run. Once the car is connected to a specific fob, it only accepts signals from that device. This means that other fobs will not work with the vehicle even though they look the same. This helps to protect the integrity of the vehicle's computer system and prevent the use of unauthorized key fobs to gain control over the vehicle.
