Thanks for the ideas.
Called ford and told them my wife was stranded with the kids; i'm told there is no quick fix open the door method but bring it in and they will gouge me for fixing it up.
Had a bit of a look over the Ford forum, plenty of broken actuators but none with the door locked. Comparatively there seems to be a lack of technical/practical knowledge, hence the post on here.
I'm reluctant to unbolt the hinges because it doesn't look like it'll work; the striker bar is mushroom shaped to prevent you from removing the door when locked. If it does work then you've got the problem of re-aligning it.
Which leaves.....remove all of the other trim to access the screw in the end of the door (Good idea)
I'll keep you posted
