Modern smart keys and fobs are equipped with an embedded transponder which stores electronic security information in a format that is not easily copied. When your fob or key is put into the ignition, it transmits this code to a receiver in the ECU. The ECU analyzes this code in comparison to the one it has stored in its memory, and then activates both the fuel system and the ignition circuit if they match. If the codes do not match then the engine will not start even when the ignition circuit is short-circuited by a thief.
