Possible uses of keys in description titles are suggestions only. Actual uses are left to buyers’ expertise and research. All vintage keys are used and may have wear or discoloration commensurate with age and use. We have a 60-day money back free return policy for non-international purchases and consider reasonable offers made. See our Store for hundreds more collectible keys and over 2900 other vintage items, including vinyl, 8-tracks, cameras, watches, figurines, and more. We will combine shipping on purchases made the same day.
