I tried Home Depot and they did not have the blank for my TRIOVING cabin door lock on my 2012 R29. I then called the best independent locksmiths in Beaverton, Oregon and was told that they did not have the blank.
Ranger was out of blanks as well, so I ordered 2 blanks online from Europe Trioving at about $10 each, but the freght for 2 little keys via mail, was over $35. But what the hell, I did not want to be without a spare.
I took the blanks to the above locksmith, who thought it was interesting that I was told they did not have the blanks, and proceeded to find the blank. He said it was in his European key section, and most GOOD Locksmiths should have the blank. The number is ILCO T06
I hope this save someone else some $$$ my spares could have costed $7.50 versus over $70. But I do have spares and peace of mine.
