Have a 09 Mazda 3 that came with locking lug nuts on it. The dealer put them on because they would have the wheels stolen off the cars on the lot since it is at the edge of town. However I'm more cocerned that sometime I'll need to get a wheel off and not be able to get the lug nut loose. I've never had them before and haven't had a problem so I'm thinking why ask for it. What is the opinion of those here?
