Transponder Chips
If your car is made within the past 20 years, it is likely that it has a transponder chip inside of it. It's the tiny plastic piece in the head of your car key that houses an RFID (Radio Frequency ID) chip that has a unique code to your car.
The chip emits an unintentional radio signal when it is activated by an electromagnetic field. This signal then gets amplified by the specific antenna that is positioned around the barrel that controls your ignition in your car. programming car key in the vehicle is then able to verify that the chip in the key's transponder is the correct one for your car.
This prevents the vehicle from being started through hot-wiring or manipulating. The chip inside the key also confirms that you are the legitimate owner of the vehicle. This can reduce car theft.

When the transponder key is inserted in the ignition barrel, a circuit within of the induction coil will send out a signal. The signal will be absorbed by the chip and cause it to transmit a signal back to the car. If the computer on the car detects this signal as the correct one, it will shut down the vehicle immobilizer and allow the engine to start.
If the car doesn't recognize the transponder as being the proper signal, it will not start the engine, and will warn you with flashing lights and a siren. This system is designed to deter those who would attempt to alter the vehicle. However, it is not an absolute security measure. A skilled and determined thief might be able get around this system employing a device designed to intercept the signal.

Key Fobs
Key fobs today do more than just lock and unlock doors. They can also start the vehicle from a distance, make chirping sounds to aid in finding a car, or turn on the heated steering wheel. These extra features could make it difficult to find your car keys.
Key fobs use radio frequencies to communicate with each other and the car. These frequencies are transmitted by a small antenna in the middle of the key. The communication is encrypted, which helps stop others from stealing and replicating the signal.
There are several ways to program a key fob depending on the make and model. Some cars allow you to do it yourself. However, most newer models require you to visit a professional locksmith or dealer in order to program a new key fob or an additional one.
When you press the button on your key fob, the microchip inside transmits a code to the car's receiver that it is linked to. The receiver compared this information with the 'allowed' signals inside the fob, and either opens or closes the door. If the data does not match, the car will not be allowed to operate.
Once the car is linked with a specific fob it will only receive signals from that specific device. This means that other fobs will not work with the vehicle even if they appear similar. This safeguards the integrity of the computer system of the vehicle and stops unauthorised key fobs from taking control over it.
The majority of newer dealers will only work on a car with original fobs or genuine replacements supplied by the manufacturer. This is because the only place with the experience to design the replacement fob is a dealer's service department. Some fobs from the aftermarket, especially ones for older models that have less sophisticated systems can be programmed with out the need for a dealer.
