When the transponder key is placed in the ignition barrel, a circuit within of the induction coil will send out a signal. The signal is absorbed by the chip, which sends a signal to the vehicle. If the computer onboard the car recognizes the signal as being correct, it will disable vehicle immobilizer so that the engine can start.

If the data doesn't match an chirping sound is heard and the car isn't allowed to operate.
After the car has been paired with a specific fob, it only accepts signals from that device. As a result, other fobs will not work with the vehicle, even though they appear similar.
