Wheel locks are a theft deterrent that replace your vehicle's lug nuts and can only be unlocked with a key that comes with the set. They come in a set of four so you can replace one lug nut per wheel with a locking nut. This can help secure your wheels and keep them from being an easy target for theft. Always tighten wheel locks and lug nuts to the manufacturer's specification with a torque wrench. If you are thinking about or have purchased custom wheels, protect that investment with wheel locks. They are a less expensive option than having to buy another set of wheels if they are stolen. At O'Reilly Auto Parts, we carry wheel locks and torque wrenches for all your wheel security needs.
