    This information is typical of a Sargent & Greenleaf (S&G), Ilco, or LaGard safe Mechanical Group II Combination Locks.

    Combination Operating Instructions:
    To unlock the safe use the "Opening Index" (located at the 12 o'clock position) on the dial ring for each number. You must dial the combination precisely without backing up.

    - Left 4 or more turns to the left (counterclockwise) stopping at the first number "20"
    - 3 turns to the right to the 2nd number stopping at "40"
    - 2 turns to the left to the 3rd number stopping at "60"
    - Right to open: turn the dial to the right until it stops moving.

    There are a few safes out there that are R-L-R instead of L-R-L. In that case, you utilize the same procedure except that you would reverse the direction.

          If you can’t open the safe, try one number high or one number low when dialing up the lock. My safe was off by one number and it would not open. Its trying, but you have to have patience.

                                I have just received an old sears roebuck and company safe with Yale on the dail- with no lever-just a knob to pull. If possible could you give me some help on how to open. I've just started watching your video classes and look forward to watching more and hopefully taking some classes. Thank you for your time regardless of being able to help me.

                                    Your safe combination lock is failing. If you get the safe open, do not lock and replace the safe combination. I recommend you call a locksmith.

                                    Its a pain lol. Check out your owners manual or go to the Sentry Safe website or call your local locksmith.

                                  Hi ! Thanks for such a detailed video. I would appreciate your guidance on a related matter. We have a new safe with La Gard combination. Its user manual is not as comprehensive as your video. It says that factory set combination is ‘50’. With only one number ‘50’ described as combination, we are confused whether the 3-number combination could be with same number (50-50-50) or it is only 1-number factory setting ‘50’. We would like to change the combination, but are not sure if we should it with an assumption, as we might end up with a jammed lock. Could you please guide whether it could be simply one number ‘50’ that has been set 3 times? Thanks for your help.

                                    Yes, it is set on factory code. Just follow the video. Note: Do not lock the door of the safe until you have tested that the new code works a minimum of three times in a row to open before locking it. Example: lock it open and test new code.

                                  okay I have a question my nephews and my sons we're trying to watch videos on how to break into a safe and so they attempted to mess with my step dad's gun safe well since they did that and we're holding the lever the whole time they've messed it up where now the combination will not work the only other option is cut it open or calling a Safecracker for for $500 is there anything I can do to try to do it without having to cut open the side maybe even pop the lock if I can I don't know

                                    Sounds like the forced or broke the handle. Not a hard job to open but will require a safecraker.
