I have acquired a used set of OEM panniers for my 2019 ATAS. These have lock cylinders installed but no key. Fortunately the previous owner left the cases locked in the open position. I have ordered new lock cylinder kits for the panniers and am comfortable with setting up new lock cylinders for my bike's key. So far I have been unable to find a video that shows removal from and reinstallation of the lock cylinders in the actual pannier cases. I would be more comfortable if I could see this done before I start to take these apart. Does anyone have link to a video or illustrated PDF that shows the procedure?
