2. Make sure the locks are open. To open
locks, slide the handle forward and
pull it out to the maximum extension.
The lock will swing to the open position

hold the handle all the way out and
use a pry bar to rotate the lock into the
open position. Do not put your hands
or fingers on or near the lock jaw.
