1978 R80/7. I ordered a few of the folding key blanks and some of the non folding blanks from Motobins and shipped to me here in the USA. Though they are for my airhead according to the website and my research, they seem to have a slightly wider channel in them compared to my stock key. Went to two VERY reputable locksmiths here in Chicago, and both had the same issue getting them to cut deep enough to work. Has anyone had this same issue or is there a trick to getting these cut correctly?
