The chip sends out an low-level radio signal once it is activated by an electromagnetic field. The signal is then taken up by an antenna attached to the barrel of ignition. This allows the computer in your vehicle system to confirm that the transponder chip inside the key is the right one for your particular car.

When the transponder key is placed in the ignition barrel, a circuit within of the induction coil will send out the signal. The signal will then get absorbed by the chip and cause it to send a signal back to the car. If the computer inside the car recognizes the signal as being correct, it will disable vehicle immobilizer to allow the engine start.
If the car doesn't recognize the transponder as the correct signal, it won't start the engine, and will alert you with flashing lights and siren. This function is designed to discourage those who would attempt to alter the vehicle. However, it is not a foolproof measure of security.

The receiver compared this information with the 'allowed' signals inside the fob, and either locks or opens the door. If the information does not match, the car will not be allowed to operate.
After the car has been connected to a specific fob, it will only accept signals from the device. This means that other fobs won't be able to work with the vehicle even if they have the same appearance.
