On the discovery 2 the handle fixed to the outside of the driver’s door also has the key lock barrel, when you put your key into the lock, and twist the key a rod attached to the barrel inside the handle then in turn, turns the locking mechanism, this pin inside the handle is made from cheap cast metal, so it is weak and breaks easily and true to form mine has broken, I went to Harwood land rover today and explained my problem, there parts man told me the pin is part of the handle and is not sold separately , I can sell you a new handle, £132.99, I thanked him very much for his help and walked out of the parts department, muttering to myself. Can anyone help me with this problem.
