Wheel Locks
Wheel Locks come in packs of 4, they're not meant to replace all the lugs on your tires, just one on each. I kept the 4 lugs removed in my 4Wheeling kit as spares just incase. Once I lost the key and had to order a new one from McGuard, they charged my $12 for the new key. When you buy the key it comes with a code that identifies the lock needed so keep it in a safe place where it won't be damaged. Most tire places charge about $15 a wheel to remove the lock lugs.
