Transponder Chips
Transponder chips are likely to be found in vehicles manufactured within the last 20 years. It's the small plastic piece inside the head of the car key that has an RFID (Radio Frequency ID) chip with a code unique to your car.
The chip emits an unintentional radio signal when it is activated by an electromagnetic field. This signal is then absorbed by a special antenna that is attached to the ignition barrel. The computer system of the vehicle is then able to verify that the transponder chip of the key is the correct one for your car.
This is the reason why from modifying or hot-wiring the ignition system of the vehicle to get it started. The chip inside the key also verifies that you are the legal owner of the vehicle. This helps to prevent the possibility of theft from your vehicle.

When the transponder key is inserted in the ignition barrel, a circuit within of the induction coil sends out an electrical signal. The signal is absorbed by the chip, which sends a signal to the vehicle. If the computer on the car recognizes this signal as being the right one, it will turn off the vehicle's immobilizer and allow the engine to begin.
If the vehicle does not recognize the transponder signal as the right one, it will keep the engine from running and will notify you by flashing its lights and sounding an alarm. This function is designed to discourage people from tampering with the vehicle. However it isn't an absolute security measure. A skilled and determined thief can still get around this system by using a specific device that detects the signal.

There are several ways to program a key fob depending on your vehicle's make and model. You can sometimes do this yourself, but the majority of newer automobiles require an expert locksmith or dealer to program a replacement or an additional fob.
When you press a key fob's button it transmits a code to the car's receiver that it is linked to. The receiver compared the information with the permitted signals stored on the key fob and then opens or locks the car door. If the information doesn't match the fob's information, the car won't be allowed to drive.
Once the car is linked with a specific fob, it will only receive signals from that device. In turn, other fobs will not work with the vehicle even though they look the same. This helps to protect the integrity of the car's computer system, and also to stop the use of unauthorized key fobs to gain control of the vehicle.
The majority of newer dealerships will only accept cars with original fobs or genuine replacements offered by the manufacturer. This is because the process of creating a replacement fob requires technological and security expertise that can only be found in the dealer's service department. However, some fobs from the aftermarket typically for older models that have less sophisticated systems can be programmed by customers without the need for dealers.
