        What's the purpose of the four slots in the drive cam? If you put the spline key in at a wrong slot it would just change your code but this could be fixed with changing it later. Also the hundred numbers are dividable by 4. So also no trouble with fractions of a number.

          I’ve watched this video about six times just because the gentleman explains it so well and speaks clearly and concisely. He should be a professional voice person. I may just change my electronic lock just so I can watch it again and perform the same tasks. Very well made video.

              Manufacturers can make the door of safes 3-4 times stronger by beefing up the steel where the door bolts retract in and out from. Instead of using the thin metal inside even though ones safe door may have a 1/4 inch or 1/2 inch plate steel on the front use 1/4 to 1/2 inch steel within the door bolts frame where they retract from, that way if one is actually getting a pry started, the bolts won't bend the thinner metal that the bolts are housed in or retract from. I know most attacks are from the sides and not the door, though imagine the PEACE OF MIND with that added steel within the door.

                  Which position of the spline key I should pick up if the lock is in flat position, like in the floor safe

                    @StagArmslower The spline location is selected to locate the third number forbidden zone close to zero so you can safely avoid it. It is always assumed that your index pointer is UP on the door. In a floor safe you need to visualise the relationship with the index pointer and the lock alignment as if the index pointer was facing UP to pick the correct spline slot.

                    @sargentandgreenleaf1 you have to decide in what position you insert the spline, does this depends which way the locking bar moves versus position of the opening index line on the dial backing plate.

                    Stag, I am not sure what you mean by "flat." The lock can only be mounted VD, VU, LH and RH.

                  I always wondered how locks were set after install. How do your locks stand the test of time or do rely on the safe manufacturer to design a door that prevents access to the tumblers?

                            So if I have lost my combination...and I have access to the back of my door...I can manually move the mechanisms inside the lock to accept the change key...and start all over?

                              Some safes have a frangible glass relocker but this is rare and usually for very valuable items (expensive safe) . Such a relocker CAN be damaged by very rough handling.

                              I would check with the safe manufacturer on the proper moving process. You may want to remove the relocker until you get the safe moved.

                                    One of the cam clutches is probably closed when it should be open. It takes a lot of deep thought or a visit to a locksmith to get it sorted out.

                                  Even though it is conventional to begin dialing to the right for the first number -- shouldn't it be true that one other working combination will exist that begins in the opposite direction?

                                    On these locks the plunger is retracted when turning clockwise/right and the cam gates all have to be aligned before that. So for a 3 wheel lock you get L-R-L-R and a 4 wheel lock it would be R-L-R-L-R .

                                  I can't get the change key to insert all the way at the step of a new install and combination. What could be my error?

                                    Most likely incorrect combination tried or incorrect index pointer used.

                                        In the video the part with the hex/Allen key describes how to reset the wheels when the combination is not known.

                                        The big danger in these types of locks is rotating the change key when it is not fully through all the cams as some of the clutches may remain unlocked. This is why it is important to only use the change key with the cover on and make sure the flag goes all the way in. A competent locksmith should be able to realign the cam clutches if they are out of synchronisation but a replacement used lock may be cheaper.

                                        I worked out the problem I caused and how to fix it after working on my first ever dial combination lock for a hour without help from the internet so it can be done if no parts are bent or damaged.

                                        maybe not all wheels are aligned correctly? Maybe the change key is bent? Did you dial the old combination correctly?

                                          Is it possible to install this on horizontal flat surface? I mean when you open the door by lifting if from horizontal flat position?

                                            Yes. Select the spline location by visualising the dial index in the UP position when determining the lock orientation.

                                                I have accomplished everything successfully concerning setting the combination. My issue is that despite this, the brass rocker arm that engages the bolt (VD) in my case, DOES NOT disengage the bolt when the correct combination is provided and the dial is then turned to the right to dead stop (to lift the bolt and enabling the wheel to turn the lock bars inside).
                                                Nothing seems to 'work with' this rocker arm within the machinations of the lock. When the CORRECT combination is acquired, what tells it to DISENGAGE? I am not 'seeing' it?

                                                  If you are looking at the rocker arm you probably have the back cover off. You need to depress the small relocker lever that is normally held down by the cover to allow the bolt to move.

                                                The pin on the relock bolt I think has broken off my safe. I can unlock the lock and go 5 past zero on the right fourth turn, which means the lever fence has dropped in the drive cam gates, the lever nose engaged to lift the primary lock bolt. But the main  safe door bolts still can not be turned and remained locked, indicating to me that the relock bolt has deployed, locking the main bolt cam.  So what do I do? Blow torch? This does not appear to be a problem a locksmith can handle.

                                                   Not sure what lock you have but it doesn't sound like the lock bolt is fully retracting. If so it could be that the internal lock case relocker has fired due to loose lock case cover screws. Try smacking the safe door outside the dial ring area with a dead blow hammer while trying to gently turn the dial further to completely retract the lock bolt.

                                                  Excellent video. Thanks. Changed out a 6120 that failed with the 6730 as shown

                                                    Thank you! I used your instructions to replace a digital lock and keypad with an S&G 6730-112 combo lock. The S&G has a very solid feel to it, dial rotation is VERY smooth, its batteries never go dead and its ribbon cable won't short out.

                                                            My opinion. I didnt like it. Simple as that.

                                                              What was terrible about it? It was very informative and well done.

                                                                You don't have the change key turned properly. Usually happens when you try to change the combination the back of the lock off....

                                                                Or the change key hole on one of the wheels if not in alignment with the others which means that while 2 of the wheel are in combo changing mode one is turned in the other direction.....again, usually done when the back is off...
