I was searching around looking for wheel locks...someone I know had his wheels stolen, and his car was left sitting on the ground after the plastic 'boxes' went limp...and btw, it's a Honda Civic....no comment...sooo, check out Gorilla Guard's website...pretty interesting tech...a key of course, but the outside diameter around the key area turns...so no grip and no room for a steal your rims tool...anyway, thought I'd throw it up...feedback appreciated
