On opening our caravan lock after it being stored over the winter, I couldn't open the door lock. Infact the key nearly snapped. Its on a Swift 540 only 2 year old and its a Hartal lock, its very stiff the latch on the inside to open & close also,any suggestions on how to ease the stiffness of the opening and closing or will WD40 do the trick?
