When the transponder key is inserted in the ignition barrel, a circuit inside of the induction coil sends out a signal. The signal will be received by the chip, causing it to transmit a signal to the car. If the computer inside the car detects the signal as being correct it will turn off the car immobilizer to allow the engine start.

When you press a key fob's button the microchip inside sends an informational code to the car's radio that it is paired with. The receiver compared this information with the 'allowed' signals on the fob and either locks or opens the door. If the information isn't in line, a chirping sound is heard and the car isn't allowed to operate.
Once the car has been connected to a specific fob, it can only receive signals from the device. In turn, other fobs will not work with the vehicle, even though they have the same appearance. This protects the integrity of the car's computer system and to prevent unauthorized key fobs from gaining control over the vehicle.
