just bought a 99 rx300 w/ 57000 miles and was going to have my mechanic check the brakes and pads, but he can't get them off without the missing lug nut key. Bought the car from a small dealership and they said they don't have it. Don't know if these are the original lug nuts. Do Lexus dealerships have spare lug nut keys? any help is appreciated!
