* Safety glasses
* Gloves

Steps:

1. Preparation: Park your car on a level surface, engage the parking brake, and use wheel chocks.
2. Adjust the Wrench: Adjust the universal lug nut wrench to the appropriate size for the locking lug nut. Ensure a snug fit.
3. Attach the Wrench: Place the wrench over the locking lug nut, making sure it is securely seated.
4. Loosen the Lug Nut: Use the wrench to loosen the locking lug nut. If needed, attach a breaker bar to the wrench for added leverage.
5. Remove the Lug Nut: Once the lug nut is loose, remove it completely.
6. Repeat: Repeat the process for the remaining locking lug nuts.

Limitations of Universal Lug Nut Wrenches:

* They may not work on all types of locking lug nuts, especially those with complex patterns.
* The grip may not be as secure as with specialized tools, increasing the risk of slippage.

### 3. Welding a Nut to the Locking Lug Nut (Advanced Method – Requires Welding Experience)

This method involves welding a standard nut to the locking lug nut, providing a solid point to attach a wrench. This requires welding equipment and experience. If you are not comfortable with welding, do not attempt this method.
