Wardrobe Key Blanks. Most of these keys do not need cutting, but some do! If you find a key that looks like your key it will probably fit, as there is no security in the lock, it just moves a bar in and out to operate the lock. Last year we sold over 3,000 Wardrobe Keys and only had one back which did not fit. If you need a replacement key for any Ducal wardrobes, please use a Huwil wardrobe key.
