Transponder Chips
If your car was manufactured in the past 20 years, chances are it contains a transponder chip within of it. It's the tiny piece of plastic in the head of the car key that has an RFID (Radio Frequency ID) chip with a unique code for the vehicle you own.
When it is activated by an electro-magnetic field the chip emits a low level signal. This signal is then amplified by the specific antenna that is attached to the ignition barrel of your car. The computer system of the vehicle is then able to verify that the chip in the key's transponder is the right one for your vehicle.
This is what stops doing hot-wiring or altering the ignition system of your vehicle to get it started. automotive key programming inside the car key ensures that the owner is the person who owns the vehicle. This helps to reduce the risk of theft from your car.

A circuit within the induction coil emits signals when the transponder is placed in the an ignition barrel. The signal is absorbed by the chip, which then transmits a signal the vehicle. If the computer in the car recognizes the signal as valid, it will disable vehicle immobilizer to allow the engine start.
If the car isn't able to recognize the transponder as a valid signal, it won't start the engine, and will notify you via flashing lights and an alarm. This feature is designed to discourage those who would attempt to alter the vehicle. However it's not an absolute security measure. A determined and skilled thief could still evade this system with a specially designed device that detects the signal.

Key fobs today be more than just a way to lock and unlock doors. They can also start the car from a distance, make chirping sounds to help locate the car, or switch on the heated steering wheel. These extra features can make it difficult for you to locate 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 inside the middle of the key. The communication is encrypted, which helps to keep others from stealing and retransmitting the signal.
Keyfobs can be programmed in a variety of ways depending on the model and make of your car. Certain cars let you do this by 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 a signal to the receiver inside the vehicle with which it is paired. The receiver compared this information to the signals that are allowed inside the fob, and either opens or closes the door. If the data doesn't match an chirping sound is heard and the car isn't allowed to operate.
After the car has been associated with a particular fob, it will only accept signals from that device. Other fobs won't work with the car, even if they look similar. This safeguards the integrity of the computer system in the vehicle and stops the use of unauthorized key fobs to gain control of it.
The majority of car dealers who are newer will only work on cars with original fobs or genuine replacements supplied by the manufacturer. This is because the only place that has the experience to design a replacement fob is in a dealer's service department. Some fobs from the aftermarket, especially those from older models with less sophisticated systems can be programmed without the need for a dealer.
