The chip emits a low-level radio signal when it is activated by an electromagnetic field. This signal then gets taken up by the antenna that is fitted around the ignition barrel of your car.

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 received by the chip which sends a signal to the vehicle. If the computer onboard the car detects the signal as correct, it will disable vehicle immobilizer to allow the engine start.

The receiver compared this information to the 'allowed' signals inside the fob, and either opens or closes the door. If the information doesn't match, the car will not be allowed to operate.
Once the car is linked with a specific fob it will only receive signals from the device that is associated with it. As a result, other fobs won't be able to work with the vehicle even if they look the same.
