I then applied 12v to same wires on the Fantom but without success. So next step was to remove my door cards & try wires as they exited the lock, again no luck so it looks like lock blown. only option left was to remove back off lock whilst inside door, this was actually quite easy and enabled me to get inside lock to release - finally success! with lock motor out I discovered a burnt out armature which was holding lock in superlock mode preventing the door from being unlocked from inside the vehicle. once dorr was opened first thing I check was that child lock was in fact not activated and it wasnt.
I not sure yet wether to swap locks out for the ones in spare as I like the idea of no possibility of being locked in the vehicle if battery goes flat or something else goes haywire so for now I will lock rear doors manually.
As it turned out other side door had very same problem. So somehow when BECM got drowned it caused both rear locks to burn out and activated superlock ( what a handy feature ).
