Key Blank - ILCO KW14R Note: Double check your keys and this information. There seems to be two types of keys, beginning with either an "A" or "B". If you have an "A" key it should be a "KW14R" key-blank. If you have a "B" key, it should be an "KW14" key-blank. This was true on the 2008. But I'm not sure how they may be on newer models (so double check).
