I've learned from Hall's the gas cap key blank for my 2006 TE 610 is no longer available. I am not so comfortable with only one key. Has anyone found a substitute that will work? EDIT: Ilco brand: X140 VL8 are the numbers on the blank.
They sub out the gas cap. Cant remember the name of the company off the top of my head. A lock smith out in Bishop looked it up for me. He named some other manufacturers using their keys, mostly oddball stuff, can't remember all of them, but I remember Porsche was one. He said the key way is odd, but if I checked the blanks from the other manufacturers they would likely be using a key with the same key way profile. Otherwise your stuck getting a whole new gas cap assembly that comes with 2 new keys ~ $90.
Success -- I finally found a locksmith who was willing to look through his blanks and find something. He used a blank for a Volvo (unknown vintage). The blank was too wide and too long, so the blank would not fit in the gas cap lock. But the lands and grooves were correct after cutting it works perfectly.
