Check either side of the lock for the provision of a screw. Remove the screw to separate the two main housings parts of the lock.

The spring provided to maintain the latch in the out position so that the door remains closed when shut. The spring locates onto a protrusion to prevent it slipping.

The rotating locking device moves along its separate housing, and this movement allows the device to be removed and to be reinserted. Either side of the rotating locking device is supposed to be identical. The difference in shape is caused by wearing of the metal during use. To restore your door lock to full working order, you simply dismantle the lock, turn the rotating locking device around, and reinsert it. Then place the spring back in position before securing the two main metal housing plates back together using the securing screw.

Place the lock back into the door and secure the retaining screws. Slide the metal bar through the central hole and bak into the door handle that is still secured to the door. Refit the door handle that you previously removed. Check that turning each handle does operate the latch. The watch should now return fully into the door lock allowing ease of use.
If a previous repair has already been undertaken to turn a worn rotating looking device around, then you will need to obtain a new device or a new lock for the door.
Hope this helps you in some way,
Happy DIY
