I disconnected my battery when this happened., and it forgot the code.
Maybe you need to leave it for longer with the battery off. If you can get in it's one of the green wires above the glovebox which comes from the OBC and stops the fuel pump working.

Yes. If the car has an OE alarm as well, the alarm immob and OBC immob will be connected in series near the plug in question.
The immob interupts the ignition feed to the C101 connector.
Laughably easy to bypass.
P.S. If you want a secure alarm, arrange it to short circuit the fuel punp supply as well as break the ignition supply.
