Transponder Chips
Transponder chips are likely be found in vehicles manufactured within the past 20 years. It's a small plastic thing inside the head of your key which contains a RFID (Radio Frequency Identification) chip with a unique code for your particular vehicle.
When it is activated by an electromagnetic field the chip emits a low level signal. The signal is then absorbed by the special antenna that is attached to the barrel that controls your ignition in your vehicle. The computer system in the vehicle can then verify that the transponder chip of the key is the correct one for your car.
This is the reason why hot-wiring or tampering with the ignition system of your vehicle to turn it on. The chip in the key also verifies that you are the legal owner of the vehicle. This helps to reduce the risk of theft from your car.

When the transponder key is inserted in the ignition barrel, a circuit inside of the induction coil sends out the signal. 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 correct one, it will shut down the vehicle immobilizer and allow the engine to begin.
If the car doesn't recognize the transponder as a valid signal, it will not start the engine and will notify you via flashing lights and an alarm. This function is designed to discourage people from tampering with the vehicle. However, it is not an unbreakable security measure. A determined and skilled thief can still get around this system by using a specific device that intercepts the signal.

Key fobs today can be more than just a way to lock and unlock doors. They can also start the vehicle remotely, make chirping noises to aid in finding cars or switch on the heated steering wheel. These additional features can make it difficult to locate your car keys.
Key fobs communicate with one other and with the car through radio frequencies that are transmitted by an antenna that is located in the middle of the key. The communication is encrypted, which helps stop others from stealing and re-transmitting the signal.
Keyfobs can be programmed in a variety of ways depending on the model and brand of your car. Certain models allow you to do it yourself. However, the majority of newer models require you to visit an expert locksmith or dealer for them program a replacement key fob or additional one.
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 compared this information with the signals that are allowed on the fob and either opens or locks the door. If the information doesn't match an chirping sound is heard and the car isn't permitted to function.
Once the car has been connected to a specific fob, it will only accept signals from the device. In turn, other fobs won't be able to work with the vehicle even though they have the same appearance. This safeguards the integrity of the computer system in the vehicle and stops the use of unauthorized key fobs to gain control over it.
Most newer car dealerships will only deal with cars that have original fobs or genuine replacements supplied by the manufacturer. This is because the only place with the knowledge to create an appropriate replacement fob is the service department of the dealer. Some fobs from the aftermarket, especially those for older models that have less sophisticated systems can be programmed with out the need for a dealer.
