The lens zoom and locking mechanism to the camera body are completely independent of each other, so it shouldn't be a related problem.Fell off my desk yesterday and it was fine when I checked it, came use it at the MetroCentre this morning and it was completely locked
Try taking it to an independent dealer, such as the one in Sunderland, as they may be able to fix it for you. This one has been around for years - http://www.charleseaglesandson.com/sunderland%20branch.
