The door on my Peugeot 307 refuses to unlock?

One of the doors on my Peugeot 307 locked itself and has refused to unlock, both through the inside and through outside
We would at this stage try spraying something like WD40 / penetrating oil into the mechanism to see if the lock itself it just jammed or stuck. If this doesn't work then you will need to strip the inside door panel and see what the actual fault is.
