Dont do different ones just use only locking lugs. And to a thief it does matter. Ask me how I know. Its bout slowing a thief down and if I have to take off 5 locking lugs on every wheel it will take me forever and it wont be messed with. Anyone who tells you otherwise isn't using their sense. It takes time to get a locking lug off and sometimes breaks your tool so if you have every lug nut as a locking one only then are you safe. -ask a theif
