hi we have a abbey vogue 540.We have just found out that the lock can not be undone with the key,very stiff to turn.The main problem is that we are away for 2 weeeks and unable to lock door.I have taken the lock off and used wd40 but no good.The site we are staying on is an abbey stockist and we asked there ,but was told to refer back to where we bought our one from.Has any one come across this and know of an easy fix.Other wise its a round trip of 200 hundred miles and they proably wont be able to sort out sraight away. Thanks peter
