On the other end of the lock tumbler, there is a small nut or bolt (I can't remember which) which holds the tumbler in and also retains the offset piece of metal which swings up to "lock the door". Probably that small nut or bolt has worked out and now the tumbler is going round and round 360 degrees. The tumbler may even come out with the key if you try to lock the door with the key. It is really an easy fix, since the nut or bolt is still in the door case, if it fell out completely. Problem is that it is a large Pain In The A** to remove the door panel to access these pieces. There are pop out plastic retainers which hold the door panel on, around the edge of the panel, once you remove the up and down screws which secure the black arm rest/pull handle. The pop out plastic retainers are as likely to pull out of the back of the door panel as pop out of the metal door frame. They make large flat bladed upolstery panel tools, with a slot in the middle, just to pop out these plastic retainers without stressing the back of the fiber panel material. These are available in about any auto parts store, in the speciality tool and parts section. Once you have the panel off, it is easier to completely remove the outside door handle (2 nuts and 2 U clamps, and a very small rubber and bell crank lever to the inside handle. This bellcrank just pulls apart and pushes back together), do your repair while learning the layout, and then reinstall the handle assembly. Trying to do the repair while the handle is still installed, when you really don't know what you are doing, and your hands are working backwards in a 4 inch space, makes it REALLY challenging. On the back of the tumbler there is the nut or bolt, the offset metal lock piece, an end cap, and a small circular spring which provides the tension you feel when you turn the key. This tension is what makes the key come back to the neutral position. Be sure you locate all these pieces in the door case if the thing fell apart completely. If you don't have a breakdown photo or drawing of the door handle assembly, ask and someone on the BB will provide you with one. Finally lub the key cylinder with white lithium grease and use Locktite on the nut or bolt screw threads to keep the thing together and you from having to do this all again someday in the future.
Good Luck, Robert
