When it is activated by an electro-magnetic field, the chip emits a low level signal. This signal is then taken up by the antenna that is positioned around the ignition barrel of your car. This allows the car's computer system to determine if the transponder chip that is in the key is the right one for your particular car.
This is what prevents from modifying or hot-wiring the ignition system of the vehicle to start it. The chip inside the key also confirms that you are the genuine owner of the vehicle. This will help reduce car theft.

The circuit in the induction coil will emit a signal when the transponder is put into ignition barrel. The signal is taken up by the chip, which then transmits a signal the vehicle. If the computer inside the car recognizes the signal as correct it will turn off the car immobilizer, allowing 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 alert you with flashing lights and siren. This feature is designed to discourage people from trying to tamper with the vehicle, but it isn't a foolproof security measure.

The receiver compares the information with the 'allowed signals' stored in the key fob and then it opens or closes the car's door. If the information doesn't match the fob's information, the car won't be allowed to operate.
Once the car is paired with a specific fob it will only accept signals from the device that is associated with it. Other fobs won't work with the car, even though they appear like. This ensures the security of the computer system that runs the car and blocks unauthorized key fobs gaining control over it.
The majority of newer dealers will only work on cars with original fobs or genuine replacements that are sold by the manufacturer. This is because preparing an appropriate replacement fob requires technical and security expertise that can only be found in the dealer service department. Some fobs from the aftermarket, especially ones for older models with less sophisticated systems, can be programmed without the need for a dealership.
