Transponder Chips
If your car was built within the last 20 years, it is likely that it has a transponder inside of it. This is the little plastic piece inside the head of your car key that contains an RFID (Radio Frequency ID) chip with a unique code for your car.
When activated by an electro-magnetic field the chip emits a low-frequency signal. The signal is then taken up by an antenna attached to the barrel of ignition. The computer system of the vehicle can then verify that the key's transponder chip is the right one for your car.
This is the reason why from modifying or hot-wiring the ignition system of your vehicle to start it. The chip inside the key also confirms that you are the legal owner of the vehicle. This will help reduce car theft.

When the transponder key is placed in the ignition barrel, a circuit inside of the induction coil will send out the signal. The signal will be 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 correct one, it will turn off the immobilizer on the vehicle and allow the engine to start.
If the vehicle doesn't recognize the transponder signal as the proper one, it will stop the engine from starting and will alert you by flashing its lights and sounding a siren. This feature is intended to discourage people from attempting to hack into the vehicle, however it isn't a foolproof security measure.

Key fobs use radio frequencies to connect with one another and the car. These frequencies are sent through a small antenna located within the middle of the key. The transmission is encrypted, which helps keep others from stealing and retransmitting the signal.
There are several ways to program a key fob, based on the make and model. It is possible to do this yourself, but most newer cars require that you visit a locksmith shop or a professional 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 inside the car with which it is linked. The receiver then compares the data with the 'allowed signals' stored on the key fob and then it opens or closes the car's doors. If the information isn't in line the signals, a chirping sound can be heard and the car isn't able to operate.
Once the car is paired with a specific fob it will only receive signals from that device. This means that other fobs will not work with the vehicle, even though they have the same appearance. This safeguards the integrity of the computer system of the vehicle and stops 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 supplied by the manufacturer. The reason for this is that the only place with the expertise to prepare the replacement fob is a dealer's service department. However, some fobs from the aftermarket typically for older models that have less sophisticated systems can be programmed by consumers without the need for a dealership.
