Last fall I broke my white metal(seemed like it) socket trying to remove the security lug nut. Fortunately my indy shop came to the rescue and removed all 4 security lug nuts from the wheels . I have OEM wheels and new tires but I don't park my car in dark alleys so I am not too concerned about theft.
Cheers,G.
PS There is a company in the US that supplies these theft key sockets. You have to take a pic of the sec. bolt and send it to them. I found it just easier to get rid of the darn things.
