How do you change the ignition lock on a 1994 Isuzu pickup?

To change the ignition lock on a 1994 Isuzu pickup, first disconnect the battery to avoid any electrical issues. Remove the steering column cover by unscrewing the necessary screws, and then locate the ignition lock cylinder. Use a small flathead screwdriver to press the release tab on the bottom of the cylinder while turning the key to the "on" position, allowing you to pull out the old lock. Insert the new ignition lock cylinder and reassemble the steering column cover before reconnecting the battery.
