Had an eye opening experience today when tire shop tried to fix a flat. The wheel lock key used to remove lug nut did not fit the wheel locks.Mechanic had to re-install the other lug nuts, inflate tire, then I was off to Toyota Dealership. Toyota service said when they previously rotated tires they used their master key to remove tire locks, not mine. So I would have to order a replacement key. I said no, you guys were the last to rotate the tires so either way the key I got is used, doesn't fit, and you own it. The manager said, We can plug the tire for 35 dollars and place the order for a new key for the wheel locks. I said no, If you can't fix the tire properly with a patch then forget it. Take off the wheel locks and give me 4 new lugs nuts. I'll take it back to the tire repair shop. Manager agreed realizing I guess that was a cheap way out of losing my wheel lock key. My mechanic neighbor said you can buy the wheel lock keys online so someone determined to steel your wheels can do so with or without wheel locks. My concern was If I'd been stuck with a flat in a remote area I had no way with the wrong key of getting that wheel off. My Rav 4 Hybrid has been great other then the Yokohama tires. They will be replaced tomorrow with just 14,000 miles.
