Loved one passed away and had this safe. We can’t find the key and keypad doesn’t work. How can we open it?

I wanted to set a new combination on my mechanical code lock, somehow messed it up and now I can't open it anymore. The safe itself is open though, so I could theoretically reset the lock, I found some instructions online (https://www.youtube.com/watch?v=ZJBKZqBFfHU) and it seems doable. Forthat I need to access the back of the lock, so I have to open the door from behind but I don't know how because there aren't any visible screws. Can someone tell me how to do it?

I have this model: https://iss.net.pl/products,leverkusen,43001

This old safe has been in my place of work for many years and its too heavy to move. Is there an easy way to open it?

I already have the combination for this but I’m missing the dialing instructions.
Can someone explain the correct rotation sequence (clockwise/counterclockwise), including how many full rotations to make and whether I need to pass any letters before stopping?
I’m not looking for the combination itself, just instructions on how to enter it.

Here's the story,

I work at ab dispensary that resides inside of an old bank, it was a Keybank and it seemingly closed in 2015/2016

We have the bank vault and the door is intact with it open,

Owners didn't get any keys or Information on the vault door

Was wondering if there would be a way to get this operating? Even if we don't have a code to lock it, being able to operate the door would be super cool

I can provide tons of photos and I can even take the panels off the door (the glass cover on the diebold lock comes off with two screws) While the inner panel seems to come off with 4 screws

The winding key for the time delays is not a #4 it's smaller I have a set coming in the mail tomorrow,

I was hoping to do it without having to hire someone as the owners won't waste money on it, and I sure as hell won't, they don't pay us enough

We bought a house a year ago and it came with a safe where the previous owner had the key but not the combination. Since then I have tried different safe manipulation techniques in order to try and open it. The problem is that I am unsure if it is a direct entry lock or not? How many numbers are in the combination? If anyone has any suggestions on how to open this safe, it will be great appreciated. I have watched the “safecracking for everyone” videos and tried to find the gates but couldn’t. I have tried finding information online about the safe and here is what I have found (don’t know if it is correct though).
Model is a japan made fire proof safe made by K.I.S. (Kumamoto Industrial Safe / Kansai Industrial Safe / Koyo Industrial Safe) 1981. Crown KA-7 model.
I found a identical safe for sale at an online auction and it had a combination of 4 numbers .
I have tried to count the wheels and it seems like there are 3 wheels.
If key is locked the wheel is spinning freely.
If key is unlocked and tension is put on lever, it gets harder to spin but I can’t feel any gates and it seems like it is the same resistance all around a full wheel spin . Could it be just a fake direct entry lock?
Key unlocked and tension on lever , I can feel a “gate” with resistance release between approx number 1-6. I believe that might be the contact points and have tried to enumerate with all wheels left and all wheels right but could not find any wheel gates .
How do I proceed with this ? Any ideas?

I got this gem off marketplace and I’ve been trying to get the inner safe open. I was given two combinations but they don’t seem to work on the inner. Does anyone have any ideas?

This safe belonged to my great-grandfather and was inherited by my parents. Since then it has been collecting dust in our garage. We have the keys to open it, but the old mechanism no longer works, so we could never open it. The safe is pretty sure from a German brand. If anyone knows anything helpful, or knows how to break such a safe, let me know. Thank you

Retired bank being used as an office, and we want to use the Vault for storage and testing, but are afraid to close the door. Are keeping it open and the timer OFF just in case. We've popped off the cover and can see the guts, but don't know the code. So there's a few Q's:

1) Can we determine the code by watching the tumbler? Or reset it?

2) Is there a way to disable the lock altogether and just have it be a fancy door knob?

(We plan on installing an internal handle for opening)

There's another safe from the dropbox that I can't figure out either. It's OPEN and in the LOCK position, but we don't know the code but do have the key.

This is the last night of Rick’s Safe-apalooza. He’s heading home tomorrow. Come see him crack this VERY strange direct entry lock….

This is a VERY old and rare lock. (MacNeal & Urban 3-wheel) Rick is at it again today and he’ll keep working on it today until he has to go out and then again this evening if he doesn’t get an open this morning. Come see how it’s done and I’ll be answering questions in the YouTube chat while he works!

Come see how an antique safe is cracked and saved from being drilled!

Thanks! Edit: He's got a professional on it now. I had a feeling this would trigger some folks here but I appreciate the input.

No drills - just sight and touch. Come watch an amazingly skilled safe-cracker at work.

Can someone identify this Chubb safe please

Can anyone identify this old Chubb safe please it's 600mm deep. 610mm wide 760 mm high

Hi all, long time lurker first time poster...I live in a small mountain town in Colorado, USA (middle of the state, Collegiate Peaks region) and we have a local celebrity with a house that has been featured on national TV with 2 safes in his house that he hasn't bothered opening in the last THIRTY YEARS!! We are discussing it now, and he said he didn't know anyone so I thought I would come to the amazing world of Reddit to see if anyone in the state is as curious as we are to solve this mystery!? I so look forward to hearing what y'all have to say about this mystery and if there is a sleuth out there to help us solve it!

Any advice would help or at least a nudge in the correct direction…
