Transponder Chips
Transponder chips can be found in vehicles manufactured within the last 20 years. recommended is a little plastic piece inside the head of your key that contains a RFID (Radio Frequency Identification) chip with a unique code that is specific to your particular vehicle.
The chip sends out an low-level radio signal once it is activated by an electromagnetic field. The signal is then taken up by the antenna that is attached to the barrel that controls your ignition in your vehicle. This allows the computer in your vehicle system to verify that the transponder chip inside the key is the right one for the car you have.

A circuit inside the induction coil will emit a signal when the transponder is inserted into an ignition barrel. The signal will be taken up by the chip, causing it to transmit a signal to the car. If the computer inside the car is able to recognize the signal as valid it will turn off the car immobilizer so that the engine can start.
If the vehicle does not recognize the transponder signal as being the correct one, it will prevent the engine from running and will alert you by flashing its lights and sounding siren. This feature is designed to discourage people from trying to alter the vehicle, however it is not a foolproof security measure.

These extra features can make it difficult for you to find your car keys.
Key fobs make use of radio frequencies to communicate with one another and the car. These frequencies are sent through a small antenna located in the middle of the key. This signal is encrypted to stop others from intercepting or replicating the signal.
Keyfobs can be programmed in various ways based on the model and brand of your vehicle. It is possible to do this yourself, but most newer vehicles require a dealer or professional locksmith to program a replacement or an additional fob.
When you press the button on a key fob the microchip sends an indication to the receiver inside the vehicle that it is paired. The receiver compared this information to the 'allowed' signals stored inside the fob, and either opens or closes the door. If the information isn't in line the signals, a chirping sound can be heard and the car isn't able to function.
Once the car has been associated with a particular fob, it can only receive signals from that device. This means that other fobs will not work with the vehicle even though they look the same. This ensures the security of the computer system that runs the car and prevents unauthorised key fobs from taking control over it.
Most dealerships with newer cars will only work with cars that have original fobs, or genuine replacements offered by the manufacturer. This is because preparing a replacement fob requires technological and security knowledge which can only be obtained in the dealer's service department. However, some fobs from the aftermarket -- usually those for older models that have less sophisticated systems can be programmed by customers without the need for dealers.
