When activated by an electro-magnetic field the chip emits a low level signal. The signal is then absorbed by the special antenna that is fitted around the barrel that controls your ignition in your car. This allows the car's computer system to determine if the transponder chip in the key is the right one for your specific vehicle.

This is what stops hot-wiring or tampering with the ignition system of the vehicle to turn it on. The chip in the car key verifies that the owner is the person who owns the vehicle. This helps to prevent car theft.

When the transponder key programming key is inserted in the ignition barrel, a circuit inside of the induction coil sends out a signal. The signal will then get taken up by the chip and cause it to send a signal back to the car. If the computer onboard the car detects the signal as correct, it will disable vehicle immobilizer so that the engine can start.

If the car doesn't recognize the transponder as a valid signal, it will not start the engine, and will alert you with flashing lights and a siren. This function is designed to discourage individuals from tampering with the vehicle. However it isn't a foolproof measure of security.

Key Fobs

When you hit the button on a key fob, the microchip inside transmits an encoded code to the car's receiver it is paired with. The receiver compared the information with the 'allowed signals' that are stored in the key fob and then locks or opens the car's doors. If the data does not match, the car will not be allowed to drive.

Once the car has been connected to a specific fob, it can only receive signals from the device. As a result, other fobs won't be able to work with the vehicle even if they look the same. This protects the integrity of the car's computer system, and also to stop the use of unauthorized key fobs to gain control over the vehicle.

Most dealerships with newer cars will only work with cars that have original fobs or genuine replacements sold by the manufacturer. This is because the process of creating an appropriate replacement fob requires technical and security skills that can only be found in the dealer service department. However, some aftermarket fobs that are typically designed for older models with less sophisticated systems can be programmed by the consumer without the need of dealers.
