When your fob or key is put into the ignition, it transmits this code to a receiver inside the ECU. The ECU then compares it with the code stored in its memory, and activates the fuel system and ignition circuit if the two match. If the codes do not match, the engine won't be able to start - even if a thief tries to short-circuit the ignition circuit.
