Designed to prevent the theft of your vehicle’s expensive rims, lug nut wheel locks are a relatively inexpensive way to at least slow down the bad guys. The unfortunate truth is that if someone really wants them, they will probably get them. The object of the wheel lock is to prevent or at least slow that process down. Typically, a set of wheel locks will include four locks (one lock per wheel) and at least one key to put the wheel locks on and off. Remember where you put the key and also to never over-torque the wheel lock to the lug nut.
