HI. Suggestion: Try the dealer you bought it from. Chances are he has extras. I have modile racks in my place, not the model you mentioned, and all the keys are basically the same key and there are 2 per unit. Thanks and have a Great Day! Joe Lore ======================= I have lost my on/off key for the KF-10 mobile rack for HDD. Where can I find a replacement key for this unit?
