How do you remove the ignition lock on a 1971 Chevy Chevelle if the key is lost?

To remove the ignition lock on a 1971 Chevy Chevelle without the key, first, disconnect the battery to prevent electrical issues. Next, use a flat-head screwdriver to carefully pry off the plastic cover surrounding the ignition switch. Insert a small tool or a drill bit into the ignition lock cylinder to push in the release tab, then turn the cylinder to the "on" position and pull it out. If necessary, you may need to drill out the lock cylinder to remove it completely.
