Thanks to Andrew, I can now post Word documents here. Thought there might be some interest in the basics on the three fob system for 5.2 355/456/M/550 and the 360 and 575. This document shows you how to start your car with key and PIN alone and how to program your Alarm ECU to accept a new matched set of three fobs and new PIN.

Yell if you have any questions. I have provided new sets of matched fobs and new PINs to five owners at cost and so far we are 100% on owners being able to program their ECU to accept the new fobs and PIN. So the checklists in the document work.
