Changing combo on 8088 Sargent and Greenleaf combo lock.

[mustardmix]

Recently acquired 4 S&G 8088 combo. locks. Seller set my requested combos. Bought a change key and with instructions tried to reset combo on one on the locks. Also got instructions for seller as to how to reset combo. They were different in one way. Because the change key is for either the 8077 and the 8088, there it is necessary to lift the back of the 8077 up to change combo and not for the 8088.
Followed the sellers instructions and set new combo, but it does not open the lock. He told me not use the 0 at the end of the combo to clear and to reset it. Don't know if this is the problem or not. The gate remains up with tape but the change key was removed and now will not enter hole completely to turn. Can anyone give me hope that the lock can be reset?

If you have access to the change key hole, you will be able to figure out the combination.
Do you know how this type of lock works in general?

If you weren't careful to use the Change Index instead of the Dialing Index when you set the new combo, try subtracting 3 from every number in the one you set. So if you thought you set it to 30-20-40, enter 27-17-37 instead.

Thanks for tips

Have read lping 101 info on lock, am a novice about it otherwise. Dialing the combo sometimes takes 2x. If this is the problem when I set the combo with change key. Is there a method of finding combo?

Tried several times with ofset and 3nos. off. Will keep trying!

You need to read up how combination locks work (3 disks, set in a sequence of turning the knob in the front left and right)
Then through the change key hole you will see how many disks are set correctly.

i have one too. pretty hefty lock, takes a bit to get it the first few times.

Checked out wheels through change key hole. I see the wheel allignment. There is only one visable that blocks the change key from entering completely. It appears to be the closest one to the opening. Can you tell me if this position indicates which wheel, number in the sequence, of three is aligned, or not aligned correctly?

[mustardmix]

Would like some help!!!!

I have 4 of these locks! Before I attempt to change a second lock I want to be confident l will not have the same problem that I still have not solved even with the best experts on the planet weighing in!!!!

This sounds like the wheel in the back of the lock, but then it would be the first and only one you can see from the change key hole.
So I'm not sure if I understand you correctly.

If the issue is that the combination is not known or was set incorrectly, there is an 8077 reset tool. This tool can be used if the back cover is removed from the lock and the shutter control screw is rotated so the change key hole is open. This tool basically feels for the change key hole in the wheels and allows them to be reset one by one, then the standard change key is used to set the combination.

If this lock was working correctly before you tried to change it, there is no reason to assume that you need the use of the reset key. Using a reset key when you are not sure what you are doing is a certain way to mess things up even more.

Turn the dial 3-4 times to the left. (CCW)
While looking through the change key hole, continue turning until you see the square change key socket and immediately stop turning. Looking on the front at the change index line and note what number is in line. This number should be the 3rd number of the combination. Check this against what you thought the combo was and verify. As was stated in a previous post, if the number is "3" off then you set the combo to the opening index instead of the change index. This must be tested on 6 different combos, dialing the combo with each number correct and then -3. The change key socket is exactly 25 numbers opposite the gate on each wheel. Be careful that you are observing the differences between the two and do not get one mixed up with the other.

With the change key door open you can look for the gate on the last number of the combo. Record the dial number. With a sharp needle you can reach through the gate of the third wheel and rotate the second wheel until you line up the gate. Record this dial number. Repeat this on the deepest or first wheel. You now have the reference points of the change index. Simply add or subtract 25 and dial to the change index. You might have to try this combo + or - 1 number on each wheel, individually, until the change key goes in. You can also physically move the change socket with your needle until all three wheels line up.

When the change key goes in all the way, turn it and dial all wheels to stop on only one number like 25. You can test the opening functions using only one number more easily than dialing 3 numbers.

If, after turning the change key, the dial will not go around more than 4 turns, then you have a problem where one of the wheel's change socket is turned out of sync with the other two. This is where the reset key is to be used. It must turn the change socket on only the out of sync wheel or wheels and not the in sinc wheel or wheels.

Whatever you do, keep the change key hole open and you will succeed.

I have a problem, I was changing the combination on my lock, had to step away, one of my kids played with it. I came back and the window is closed, I tried the combo and variations a bunch of times, no luck window still open. The back is off of course.

[DayZiro]

The reset window is open? If that's the case then you're in luck. You can stick the change tool in the reset hole and feel the five or six gates as they line up.

This picture shows the holes at the bottom of the gates aligned. Push the change tool into the back as you spin the dial in the proper way to find the holes. Write down the combo and try that, but for the love of god don't let the change window close!

THANKS RAYMOND! I know this is an old thread but I came across it searching for advice regarding a locked S&G 8088 I had with an unknown combo but also having an open change key hole. With your instructions, a heavy needle and a change key I got her reset and back to "user" status, THANKS AGAIN!
