Trioving lock for Viking Yacht

Hello I want to replace a Trioving Lock for a Viking Yacht. It's a sliding door and the lock case has 5382/8 stamped on the forend. I don't need the complete lock set just the outside key cylinder, someone lost the keys! Please see the attached photo

Thanks for the photo. No problem the cylinder is easy to change and we keep them in stock, looks like you need polished chrome finish. Please see product link below
