I got back from holiday yesterday and went to unlock my car.
It's an 06 Focus ST-2
I've searched the forum and found lots about just the fob not working but nothing with both of these problems

The Fob did nothing so I changed the battery - again, nothing.
Changed it again in case battery was a dud - again, nothing.
I hooked dads car up the the car battery to make sure there was enough voltage - yet again, nothing.#

I then tried to unlock it manually with the key - key turns clockwise (as if to lock it) but not counter clockwise.

So basically I cant get into it at all.
It wasn't dead locked when I left it 2 weeks ago but the fact I cant turn the key seems really strange like it ant just be that the fob has lost its code.
I really don't wanna have to smash a window (I'd have to pay a £90 excess with insurance) but I can't see any other alternative. Can anyone help?
