Bought this car from an auction without the key. Does anyone know if this is a toyota standard wheel lock? Or at least, what key will help? Much appreciated.
The least amount of headache would be to take it to a tire shop and let them remove 'em. Any good shop will have the special tools for it. It's essentially a socket with left handed tapered internal threads that will screw down onto the lug until it's tight enough that the lug starts spinning off.
Lot of good tips here: I got tired of dealing with the locking nuts on ours, got 4 extra lug nuts (Gorilla brand, look identical).
I second that with a caveat. If you will be going to a tire shop you don't have any prior experience with call ahead first and ask if they have a key for a lock that looks like that. Then if they say they have one, but don't when you get there, you will have slightly more bargaining power. As in, "No I'm not paying you for your time because you said on the phone that you had a key and you didn't." That said, I agree that most tire shops will probably have a key that fits, because they run into owners without keys all the time.
Looks like a McGard wheel lock. The dealer may have the key kit. I think there's like 18+ variations.
