It is wrong to assume but presumably re programming the MEMS3 and thereby affecting the interaction with ring around the ignition switch has no effect on the “burglar alarm features”?

Yes, it is wrong to assume that. If passive immobilisation is removed from your engine ECU, that means you do not need your fob to start the engine. That also means somebody can break into your car by smashing window and hot wire your car and they are gone. Yes alarm should sound because opening door will triger alarm, but then just depends how quick they can hot wire your car and be gone.
