Go onto forge. Spawn 2 armor locks, pick 1 up and use it.

While you're using it press the forge button. Look at the other armor lock and press B.

Then go down to "delete all of these" press it and go out of forge.

Get in a mongoose, warthog, ghost, et. (something without a cover). You'll see yourself with the Armor lock glow around you.

You can only die from being assented or by falling into the water or to the ground from high enough up.
