The chip sends out an unintentional radio signal when it is activated by an electromagnetic field. The signal is then received by a specific antenna attached to the ignition barrel. This allows the vehicle's computer system to verify that the transponder chip in the key is the right one for your specific vehicle.

When the transponder key is placed in the ignition barrel, a circuit within of the induction coil will send out a signal. The signal will be absorbed by the chip and cause it to send a signal back to the car. If the computer in the car recognizes the signal as valid it will turn off the car immobilizer so that the engine can start.
If the car does not recognize the transponder signal as being the correct one, it will prevent the engine from running and will notify you by flashing its lights and sounding a siren. This feature is designed to discourage people from attempting to alter the vehicle, but it's not a 100% security measure. A determined and skilled thief could still evade this system by using a specific device that intercepts the signal.

When you press the button on your key fob the microchip inside sends a code to the car's radio that it is paired with. The receiver compared this information to the 'allowed' signals stored inside the fob, and either locks or opens the door. If the information doesn't match, the car will not be allowed to operate.
After the car has been connected to a specific fob, it can only receive signals from that device. As a result, other fobs won't work with the vehicle even if they look the same. This ensures the security of the computer system in the car and blocks unauthorised key fobs from taking control over it.
