Transponder Chips
If your car is made within the last 20 years, it is likely that it contains a transponder chip within of it. This is a little plastic piece in the head of your key that houses a RFID (Radio Frequency Identification) chip with an individual code for your specific vehicle.
When it is activated by an electromagnetic field the chip emits a low-level signal. The signal is absorbed by a special antenna that is attached to the barrel of ignition. This allows the computer in your vehicle system to verify that the transponder chip inside the key is the correct one for your particular car.
This prevents the vehicle from being started by hot-wiring, or by tampering. The chip inside the car key verifies 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 an electrical signal when the transponder is inserted into an ignition barrel. The signal will be taken up by the chip, causing it to send a signal back to the car. If the computer onboard the car is able to recognize the signal as being correct, it will disable vehicle immobilizer to allow the engine 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 an alarm. This system is designed to deter individuals from tampering with the vehicle. However it's not a foolproof measure of security.

Key Fobs

Many of these extra features may appear convenient but they could make it more difficult to keep the keys to your car.
Key fobs communicate with each with the car via radio frequencies which are transmitted via a small antenna located in the center of the key. This signal is encrypted to block other key fobs from stealing or stealing the signal.
There are several ways to program a key fob based on your vehicle's make and model. Some cars allow you to do it yourself. However, most newer models require you to visit an expert locksmith or dealer to program a replacement key fob, or an alternative one.
When you press the button on a key fob the microchip sends a signal to the receiver in the car that it is paired. The receiver compares the information with the permitted signals stored on the key fob and then locks or opens the car's door. If the information doesn't match the signals, a chirping sound can be heard and the car isn't able to operate.
Once the car is paired with a particular fob, it will only accept signals from the device that is associated with it. As a result, other fobs will not work with the vehicle even if they have the same appearance. This safeguards the integrity of the computer system that runs the vehicle and stops unauthorized key fobs gaining control of it.
Most newer car dealerships will only accept vehicles that have original fobs, or genuine replacements offered by the manufacturer. This is because preparing a replacement fob requires technological and security skills that can only be found in the dealer service department. However, some aftermarket fobs that are typically designed for older models that have less sophisticated systems can be programmed by the consumer without the need for an authorized dealer.
