I can't unlock my car at all - what can I do?

My Citroen Xsara Picasso 2005 won't unlock. Not with the key nor with the remote. Only the boot. Any ideas?

One of the lock servos is jammed preventing all of the others from opening. Presumably you can open the doors from inside the car. If there are grommets in the doors near the locks, pop them out and try squirting WD40 on the lock servos. Not guaranteed, but might free them off.
