#1 is a viable option, proceeding with the way you mentioned. If you do want to get a second key (peace of mind), again Needswings has, prompt, reliable an good turn around time ,on this issue.
So how are you meant to change it then Steve? Do you order one according to the vin and it's flashed accordingly?
I believe the bcm is vin specific as well?
Also, does anyone know the actual sequence of events from when the fob buttons are pressed? Ie, which component receives the signal from the fob and how is it actioned after that point.
The wiring diagrams don't always help either. For example, when fuse 9 is blown, the locking won't work, but according to the diagrams, fuse 9 is not related to the locking?
I think it does send a feed to the bcm, but what for? Maybe to a volt free contact, but its not obvious after that. It seems their system is hugely over complicated.
I think No1 is the first to try as well.
When my locking failed, the indicators on the car would still flash when you pressed the fob buttons - inferring that the fob is sending a signal and the car is receiving it.
When Lyndon uses the fob, the indicators don't flash.
