When your fob or key is placed in the ignition, it transmits the code to a receiver in the ECU. The ECU compares this code with the one in its memory, and activates both the fuel system as well as the ignition circuit if they are compatible. If the codes do not match, the engine will not start, even if a burglar tries to short-circuit the ignition circuit.
