Hi, Due to go away for the weekend, caravan packed up. Whilst unlocking the lock bolt with the socket adaptor the key (star configuation) socket end has sheared off. Weekend cancelled, and will now have to wait until Monday to talk to Alko. This is a fault that has stranded my caravan luckily on my drive, However on a campsite ready to leave for home could be a serious inconvenience. Has this happened to anyone else?
