We wanted extra keys for ours as well. The only place to get the blanks is at an RV dealer. We bought the blanks there and had them cut at ACE Hardware. I couldn't find anyone that had blanks except an RV dealer. Cost: $5 per blank and $2.50 to cut. Yeah, "RV Highway Robbery" but when you want a spare key to hide "just in case" you gotta pay
