The chip emits an unintentional radio signal when it is activated by an electromagnetic field. This signal then gets amplified by the specific antenna that is attached to the ignition barrel of your vehicle. This allows the car's computer system to confirm that the transponder chip in the key is the right one for your specific vehicle.
This stops the vehicle from being started through hot-wiring or altering the key. The chip in the car key confirms that the owner is the person who owns the vehicle. This helps to prevent car theft.

A circuit within the induction coil emits a signal when the transponder is placed in the an ignition barrel. The signal is absorbed by the chip, which then transmits a signal to the vehicle. If the car's computer recognizes this signal as being the right one, it will turn off the vehicle immobilizer and allow the engine to start.
If the car isn't able to recognize the transponder as being the proper signal, it will not start the engine and will notify you via flashing lights and siren. This system is designed to deter individuals from tampering with the vehicle. However it isn't a foolproof measure of security.

When you hit the button on a key fob the microchip inside sends an encoded code to the car's receiver it is linked to. The receiver compared this information with the 'allowed' signals inside the fob, and either opens or locks the door. If the information does not match the fob's information, the car won't be allowed to drive.
Once the car is paired with a specific fob, it can only receive signals from that device. In turn, other fobs won't be able to work with the vehicle, even though they look the same. This safeguards the integrity of the computer system that runs the car and blocks unauthorised key fobs from taking control of it.
The majority of car dealers who are newer will only work on a car with original fobs or genuine replacements sold by the manufacturer. This is because preparing the replacement fob is a process that requires technological and security knowledge which can only be obtained in the dealer service department. However, some fobs from the aftermarket -- usually those for older models that have less sophisticated systems can be programmed by customers without the need for an authorized dealer.
