How do you remove lock lug nut without key?

To remove a lock lug nut without a key, you can use a few methods. One common approach is to use a hammer to tap a smaller socket onto the lock nut, which can grip it tightly enough to turn. Alternatively, you can use a bolt extractor designed for rounded or damaged nuts. In extreme cases, drilling a hole into the center of the nut and using a stud extractor may work, but this should be a last resort as it can cause damage to the wheel.
