Open the door of the safe or room that uses the La Gard lock by entering the lock's current combination.
Press the "0" key six times, then enter the current six-digit combination one time.
Enter the newly chosen six-digit combination two times. If you enter the wrong numbers, wait for 30 seconds, then begin the process again by pressing "0" six times.
Test the lock to see if it opens before shutting the door. An audible signal will sound twice if the combination you entered is valid. If it is not, a triple signal sounds.
