Labor? They're lug nuts. Installing them yourself will take 5 minutes, and that's if you take a break in the middle to drink a beer and ponder your work.alanra said:
Wheel locks will not stop a determined, well-equipped thief. Wheel locks can be drilled out rather quickly, or the theif could simply pull your trunk lock and grab the chuck key for the locks from your trunk.
OTOH, they will deter casual or less-well-equipped theives. As you say, they cost almost nothing (and they take barely any time to install). Even if the marginal benefit is small, it seems to me that the costs are even smaller.
I've had wheel locks on both my BMWs, and would get them on every one in the future. I don't see a downside.
