The signal will be taken up by the chip and cause it to send a signal back to the car. If the computer onboard the car recognizes the signal as correct it will turn off the vehicle immobilizer, allowing the engine to start.

After the car has been associated with a particular fob, it can only receive signals from that device. Other fobs won't work with the car, even though they appear similar.
