To ensure the security of your vehicle's wheels, follow these steps carefully. First, use a suitable wrench to remove the existing lug nuts from each wheel. Once all the lug nuts are removed, replace them with the new anti-theft bolts. Make sure to align the bolts properly with the wheel holes. After positioning the anti-theft bolts, use the special key provided to tighten them securely. This will help prevent unauthorized removal of your wheels. Double-check each bolt to ensure they are all tightened to the manufacturer's recommended torque specifications. This process will enhance the safety and security of your vehicle's wheels, giving you peace of mind.
