    I agree with Aaron - it would have been easier to manipulate the dial to find the gates, especially on a safe of this type. It's not that difficult. Finding the 3rd, direct drive wheel combination number, even with false gates on it, is easy. The true gate is wider and you'll get noticeably greater variation of dial play between gate contact edges and the fence when it's in the true gate as the false gates are narrower. Search YouTube for demos on finding the numbers for the second and first wheels which are done by measuring bolt handle deflection for every fifth digit on the dial (trying 0, 5, 10, 15 . . .) and charting bolt handle deflection. For a 100 digit dial, you're into the safe in under 50 tries with the first ten or so (depending on false gates) going very quickly, and the 20 after that for the 2nd wheel number not taking all that long. With more expensive safes using higher precision mechanical combination lock components the manual cracking process is the same but requires better feel and more finesse (and experience), and it may require trying every third digit for the 2nd and 1st wheels (lower tolerance slop in the gates). Going up from there with better mechanical locks and the finesse and feel required goes up. Spending a bit of time searching for mechanical dial combination safe cracking methods for an inexpensive consumer safe like this one and using them would have saved an immense amount of time, effort and cost rebuilding the closet interior you demolished.

      Great summary on how to do it right! Yes, it could have been cracked, but likely by me. At the time I didn't even know how a safe worked. I wish it would have been a real safe, I would have paid to have someone crack it, but being that it was a tin box (not even fire proof), it was more fun to cut it open.

      Or just ask Sentry for the combination and pay them $30

        If it were a good safe, I would have paid someone $400 to crack it, but because it was a pile of shit, it got ripped off the wall and cut in half.

      "Cracking a safe" means to crack the code & OPEN IT WITHOUT DAMAGING THE SAFE. Cutting & drilling isn't "cracking". Ugh.

        @International Precision Engineering : drilling 2 holes...isn't "cracking the safe".
        Your thinking is flawed. You don't deserve the term precision in your name. & you couldn't try 1,200 combinations in 2 hours. I wouldn't let you engineer a dog house. Ugh UGH.

        I would like to clear up the age old belief that safe manipulation works by listening "to tumblers click".There are no 'tumblers' in a safe lock and nothing 'clicks' into place.

        Older, antique safes like a Hall have a weigted fence which willl fall into the gates and drive cam, clearing the passage of the bolt work which is attached to the handle. In this case the drive cam is rather passive since it is not used to actuate (throw) the lock bolt.

        A spring loaded lever lock like a Sargent & Greenleaf or LaGuard is what most modern safes have installed They are also used in all bank vaults but with four wheels instead.On those the nose of the fence drops into the drive cam and by turning the dial the fence lever retracts the lock bolt.

        Both systems can be defeated by contact manipulation, meaning that you measure the left and right contact points of the nose dropping into the drive cam which is mounted at the back of the wheel pack. The nose of the fence will drop all the way into the drive cam when all gates are aligned underneath. If there is a gate under the fence it will drop very, very minimal which you can read on the dial by measuring the minute change of distances between numbers on the dial by slightly touching the left then the right side of the nose with the drive cam. That's why many professional safe technicians use a magnifying glass above the dial and look straight down to see those minute changes. That process you never see in movies.

        Manipulation is using sight and touch only. A sound amplifier is only needed when the contact points can't hardly be felt anymore because the lock is too far away from the dial due to thicker doors. A good safe technician can open a three wheel lock in about 20 minutes.

        This Sentry safe has direct entry gates and the fence is attached to the handle or in this case the cross-lock.

        By attaching a long needle to the handle and a graph on the door, then applying pressure to the handle (or key) advancing the dial/wheels in increments of two numbers you can measure the distance and determine the combination. The furtherst the needle swings to the right is a true gate.

        The second MOE, Method of Entry is drilling a hole a quarter inch above the 9 o'clock position right into the outer dial ring, then scoping and aligning the wheels with a 70° scope.

          Sentry safes are not really that secure. The biggest kudo to them is that they are a very good safe to keep documents in should you have a fire.
          And they do keep out the small time thief.

                  You were very much on the right track. The only part you missed was the correlation between the wheel gates, the stump and the key position on the outside of the safe. By attaching a thick wire (piece of coat hanger etc) approx 6 inches long to the key, you magnify the turn of the key. The key turns slightly more, the further the stump moves into the wheel / gate. Mark positions on the safe door corresponding to the end of the wire. By noting the differences at various wheel positions - 2, 4, 6, 8 etc., you will easily find the numbers for the three gates. Then by trial and error you will find the combination. The time to open this safe should be 5 to 15 minutes. Some of these safes have a handle instead of a key hole. In this case attach the wire to the handle!

                    The key, instead of a handle, was added for extra security.
                    You'd have to pick the key lock, in addition to the manipulation of all channels.

                  The "tin shield" is not for aesthetics... the tin cover plays a very important roll of preventing the things stored inside the safe from being able to move into the lock's mechanical movements which could obviously cause a jam and then wouldn't be able to dial the combination and release the latch.

                    Just watched the video. For future reference, the disks are called the gates and the bar that drops into the gates is called the fence. I find this safe to be very low security because the last gate seems to have just one false gate. I think I broke into one of these by just applying pressure on the gates with the fence and turn the wheel until I found the gates and the fence dropped.

                    Somebody erased my comment. Maybe because I revealed too much information. I wont repeat what I said. If you were to sell the cut-away safe in the video how much would you want for the whole thing including shipping? In USA dollars please.

                          Thanks for watching. I herd a lock smith charges like $400 to open for you; prolly less if your able to take it to their shop. Otherwise, cut it open or crack it. It must be open to change the number.

                          Thanks for the video, I like the way you made a cutaway. I work as a locksmith, and I'm planning to make some cutaway safes for customers to compare.

                          Just so you know, the openings on the wheels are called gates (and false gates). The way you discussed figuring out the combination is called manipulation. Manipulation is often used by locksmiths who don't want to damage the safe they're opening.

                          I have an older model Sentry safe with key & electronic pad. (Smaller safe)
                          I couldn't open it.
                          I found the secret to opening it. You just have to bang on the top of the safe, near the front and just turn the key right.
                          Banging on the safe makes the solenoid inside disengage the lock, which opens the safe. After that, just press the button on the inside of the door to reset password code. It worked for me. I was very surprised!
                          I didn't figure the secret out, thought. I saw two other videos on Youtube that briefly mention the flaw to these safes.

                            You can call sentry or visit their website. If you can prove the safe is yours they will mail you the combination.

                            They fixed that flaw on the new safes but with a large rare earth magnet you can apply it to the upper left side and move it around. It will pull back on the "updated" solenoid basically retracting it allowing you to open the safe. Magnet needs to be around 4" in diameter and about an inch thick. Way to go Sentry!

                            I can say with confidence, this safe was pretty beefy, no rap-tap-tapping would have made her squint. up-down-left-right-hold down A and hit Start - with the digital safes, there's a whole nother level of security hacks. Thanks for the info, if you send me some more info I can try to aquire one of those digital ones and do a vid on it.

                          just noticed the serial number is on the side the little sticker the info on their is all you need to call sentry and get a the combo you just call them tell them you are the owner they will request sometimes a copy of your license with your sig be sent in also may need a notarepublics stamp but that is only a few dollars. some banks will do it free if you have a account.

                            If it were a nicer safe, especially if it were fire rated, it would be worth the efforts of trying. I stopped looking further when they said you need proof of ownership...

                            You were able to find info on it - please share? Judging by the thickness of the steel, I'd say it was a little more than that. The $100 safes are sheet metal, this thing turned out to be something like 3/16 thick.

                            Thanks for watching John. Again, I'm not a safe expert but I am an engineer and there was no way to tell that you had the correct combination as you were turning the dial (no spring loaded pins, you could not load the bolt and listen for the alignment as the last dial was bigger than the other two). I'm guessing those videos are fake. Real safe crackers have two things - ways to get information on internals for destructive cracking and tricks to reduce the number of combinations resulting in a plausible brute force attack. Like I say in the video, with knowledge of the internals I could drill one hole and open the safe in minutes and also reduce the number of possible combinations to 400 which would take an hour or so to run through...

                            There are videos on YT doing that.
                            This is the easiest safe to open.
                            I wouldn't have one of these for free.

                            Kinda their job. If I didn't cut it in half I wouldn't have been able to crack it, but I'm no master either...
