Transponder Chips
If your car was manufactured within the last 20 years, then it has a transponder inside of it. It's the tiny plastic piece in the head of your car key that houses an RFID (Radio Frequency ID) chip with a unique code for your vehicle.
The chip emits an unintentional radio signal when it is activated by an electromagnetic field. The signal is then absorbed by a special antenna attached to the barrel of ignition. This allows the computer in your vehicle system to determine if the transponder chip inside the key is the correct one for your specific vehicle.
This prevents the vehicle from starting by hot-wiring, or by tampering. 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.

The circuit in the induction coil emits signals when the transponder is put into ignition barrel. The signal will then get taken up by the chip, causing it to transmit a signal back to the car. If the computer in the car recognizes the signal as correct it will turn off the car immobilizer so that the engine can start.
If the car doesn't recognize the transponder as being the proper signal, it will not start the engine and will alert you with flashing lights and siren.

When you press the button on a key fob, the microchip sends a signal to the receiver inside the vehicle that it is paired. The receiver compares the information with the permitted signals stored in the key fob, and then it opens or closes the car's doors. If the information doesn't match, the car will not be allowed to operate.
When a car is connected with a specific fob, it will only accept signals from the device that is associated with it. Other fobs will not work with the car, even though they look identical. This safeguards the integrity of the computer system in the vehicle and stops unauthorised key fobs from taking control of it.
The majority of newer dealers will only work on a car with original fobs or genuine replacements that are supplied by the manufacturer.
