Transponder Chips
If your car is made within the past 20 years, chances are it has a transponder chip 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 code unique to your vehicle.
The chip sends out an unintentional radio signal when it is activated by an electromagnetic field. The signal is then amplified by the specific antenna that is attached to the barrel that controls your ignition in your car. This allows the car's computer system to confirm that the transponder chip inside the key is the right one for your specific vehicle.
This stops the vehicle from being started by hot-wiring or altering the key. The chip in the car key ensures that the owner is the person who owns the vehicle. This can help to reduce the possibility of theft from your vehicle.

A circuit inside the induction coil will emit a signal when the transponder is placed in the ignition barrel. The signal will be absorbed by the chip, causing it to transmit a signal back to the car. If the onboard car computer detects this signal as the right one, it will disable the vehicle's immobilizer and allow the engine to start.
If the car doesn't recognize the transponder as a valid signal, it won't start the engine and will alert you with flashing lights and siren. This feature is designed to discourage people from tampering with the vehicle. However it isn't an unbreakable security measure. A skilled and committed thief might be able get around this system employing a device designed to take over the signal.

Key Fobs
Key fobs today can be more than just a way to lock and unlock doors. They can also start your vehicle remotely, emit chirping sounds to aid in finding cars, or turn on the heated steering wheel. A lot of these additional features may appear convenient, but they can also make it difficult for you to keep the track of your car keys.
Key fobs use radio frequencies to connect with one another and the car. These frequencies are transmitted via a small antenna that is located within the middle of the key. The signal is encrypted to block other key fobs from intercepting or replicating the signal.
You can program a keyfob in different ways based on the make and model of your vehicle. Some cars allow you to do this yourself. However, the majority of newer models require you to visit an expert locksmith or dealer in order to program a replacement key fob or additional one.
When you hit the button on a key fob the microchip inside sends a code to the car's receiver it is linked to. The receiver then compares the data with the permitted signals stored in the key fob, and then locks or opens the car's doors. If the data doesn't match an chirping sound is heard and the car isn't able to operate.
Once the car is paired with a particular fob, it will only receive signals from the device that is associated with it. As a result, other fobs won't work with the vehicle, even though they have the same appearance. This ensures the security of the computer system of the car and prevents unauthorised key fobs from taking control over it.
Most dealerships with newer cars will only work with vehicles 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 service department. However, some fobs from the aftermarket typically for older models with less sophisticated systems can be programmed by customers without the need for a dealership.
