***Please note: For the above listed models *** there are two possible versions of this key. Part number 664044 is also used. The keys initally appear to be identical, but have a very slight difference in cuttable length, so they are not interchangable. We're working on a simple way to tell these apart, but until we can make that tutorial, we're recommending all customers in need of a spare key order quantity 1 of this key and quantity 1 of 664044.
