My DIY Recovering a S&G 8500 Series Lock Combonation

[BSG_314159]

So I just got my hands on a Sergeant and Greenleaf 8500 Series MP Safe Lock. So I installed it on some hardwood so i could attempt to find out the combo!



Below is a link to the manual if you do not know how to use this safe lock.

So I was going to do a whole write up on how I found out the combo but it seems like that has been done quite a number of times on LP101. Also I am a very new hobbyist in the locksmith field so it would not be as detailed. I will post some pictures and give a quick guide on how I did it.

So I removed the back cover.


Now this is my approach at acquiring the combination. I turned the dial till the first combo disk plate turned. I choose one position to line all the disks up that I could easily see. (This will not be the correct combination but it will be the correct pattern to finding the combination) I did this because of the accelerator spring being in the way of the correct location.

Here is the first disc lined up (65)


Here is the second disc lined up (47)


Here is the third disc lined up (67)


So now that I had some number now its time to adjust this set of numbers so that it opens this safe.

So I lined up the THIRD disc so I got the real 3rd combination number. (41)


Now its time for some math. I took my 3rd combination number and subtracted the real 3rd combination. (66-41= 26)

So my combination set was 56-47-67
subtract 26 from those numbers to equal
Real combination set is 30-21-41

This is after dialing the 30-21-41


Now move dial to 0 and press in. IT WORKS!!!



So this is my quick how too guide. It is a method that worked for me but may not work for others. I hope this helps anyone out there with a safe with a unknown combination.

Great guide. This should prove helpful for those looking to find the combination with the safe door open.

So my friend is giving me a safe that is closed and no combination. It is a 8500 MP just like this one I have. So now to find a way to get the combination with out cheating.

what you did to find the combo is called 'transferring'. line up all the wheel gates in 1 area and then either subtract your add to the drop-in point to get actual combo.

Thanks!! I did not know this was a method already. It just made sense in my head.
