Re: Found hidden safe, should we crack?
The suspense is killing me. Maybe we should start a bogleheads gofundme to pay for the locksmith and then I can get back to work.....
Re: Found hidden safe, should we crack?
It sounds like a lot of fun for $900 and a usable safe. What would you otherwise use the money for? Dinner, a weekend away, a fishing trip....
I'd do it!

But Feynman cracked the safes by covertly observing the owner opening it without concealing the combination.gtd98765 wrote: ↑Sun Nov 24, 2019 8:08 pmIn Richard Feynman's autobiography (Surely You're Joking, Mr. Feynman), he said he got a reputation at Los Alamos of being able to crack safes; in truth, he learned that the manufacturer had set the default combinations to 55-55-55, and the security teams usually neglected to change the combinations, so all he had to do was use the default and the safes usually opened.
If there is a default combination for your brand/model of safe that you can find, you should try it.

Re: Found hidden safe, should we crack?
The concern about not being able to open it for a burglar is uncompelling to me. OP could just pull up this thread and show it to the burglar to prove he really did not know the code.

I vote for opening it. Hopefully non-destructively so you can at least have use of it if no valuables.
One other very low probability scenario -- what if contains a non-trivial amount of illegal drugs or similar? Would you give police a heads up, or check with a lawyer before opening it?
Re: Found hidden safe, should we crack?
Gips, I just got another idea. The cost you incur to make the safe usable again can be added on to the cost basis of the property. In my opinion, that's a good reason to get this "repair" taken care of. Just be sure you save the receipt with your escrow papers.

Re: Found hidden safe, should we crack?
You said the robot has a 70% chance of success. So the
expected cost is 0.7*600 + 0.3*900 = $690.
Do you have the option of just paying $750 for them to drive out once and crack the safe and skip the robot? If so it might be an interesting option although the odds are still in favor of trying the robot.
The other benefit of the robot would be that the safe doesn’t get destroyed and could be reused. With that in mind I would pick the robot option.
Re: Found hidden safe, should we crack?
Yes there is. I'll give you a little help, you have to actually "READ" the thread not just scan for the picture or you won't find it... here's another tip that's useful in other areas of the forum - look at the OP's post history.

Re: Found hidden safe, should we crack?
Thanks so much. That's very interesting to watch. It obviously (?) isn't dialing all three digits every time, so it must use something about the way the internal disks catch on each other to allow it to try certain combinations of the last couple of digits over and over again without entering the first ones.zxllxz wrote: ↑Sat Nov 30, 2019 11:32 am[1001] The ITL Robotic Safe Cracker!

I can't quite see what interval it is trying between numbers but seems to be more than one. That is, it is relying on there being some slop or tolerance for not being precisely on the nominal numbers in the combination.
Does anyone else think that the noises it makes sound like "open the vegetables, open the vegetables, open the vegetables?"

Re: Found hidden safe, should we crack?
youtube settings allow one to play the video at 0.25 speed, so one can see the interval used (see the digital display). I suspect that for this video, he set the device to use an interval larger than one only for demonstration purposes. It might be hard to know what tolerance or slop was acceptable.
And not explained is the "clunk" and why he moved the dial manually at the end to turn the lever. Does the device stop when it detects the "clunk"? I had a little safe when I was kid and one had to try the handle to know the combination was correct.
Re: Found hidden safe, should we crack?
Some models of S&G locks require spinning the dial right back to zero before attempting to open, it's on that final turning right that the locks mechanism actually "clunks" and catches the mechanism to open the lock... its more secure than the locks that might "clunk" or something similar while spinning left to find the last number.
In the video the robot spins it part of the way and gets the "clunk" but he manually turns it all the way back to zero (actually a little past).

Re: Found hidden safe, should we crack?
I won't send money, but if I'm in the area I'd gladly donate 10 minutes of my time to try 25 different combinations. Recruit enough of us, and you'll get it cracked ... eventually.

a. May be poly (plastic)
b. May have a larger footprint than the safe door, meaning the poly body of the safe is about 3-4" below the surface of the concrete.
If you own a hammerdrill, I would buy a few cheap 1/2" masonry / concrete bits and try to drill into the side of the safe, and get a $15 Amazon camera and fish that into the safe. Depending on what you see you can decide if you want to pay to have the safe cracked.
Re: Found hidden safe, should we crack?
Does anyone know how much it costs to install a floor safe such as this? If more than the cost of opening & preserving it, you could think of it as getting a nice floor safe for free.

Essentially free if done when the slab is poured. Can't be more than a couple hundred bucks even if done later. It's just a hole in the floor.

Re: Found hidden safe, should we crack?
I did not read all the postings. But when this is only a nuisance to you then 1. drill and insert camera to know if something worth is in it. Then 2. buy a bag of concrete at HD, mix it and fill on top of the door, smooth surface and you are done for less than $100. A hammer drill does not cost much.
Re: Found hidden safe, should we crack?
Take your proof of ownership to a notary republic. prove you own the house/condo and all contents. send a copy to the safe company with the s/n of the safe and they will verify the information and send you the combination.
Re: Found hidden safe, should we crack?
I don't think we have heard from any experienced experts in cracking a safe - without damaging it.

Re: Found hidden safe, should we crack?
This thread has intrigued me from the start, waiting to see what’s inside.
Taking the picture and looking up the potential model, I noticed some of their floor safes that have the same looking door indicate a false floor. Perhaps a word of caution if you only stick a camera inside.

I would probably blow the money to have it opened out of curiosity. On the one hand, it is unlikely anyone would move and not take the contents with them. On the other hand, if someone died and no one in the family had the combination or even knew about the safe.....
Re: Found hidden safe, should we crack?
Should only cost < $100 (half for the drill bits and half for the boroscope) to figure out if the safe needs to be opened.

gonna be a long winter if we have to wait until Spring for an update!!! If it were my place, I’d try to have this non destructively opened, especially if I’m renting the place over the winter. Might be nice to be able to safely stash a few things there.
Or perhaps you could try drilling in through the concrete to see if the safe really is larger than the door and has a plastic body, as someone suggested, do the boroscope thing, and have the concrete repaired if you eventually want to have the safe in a useful condition again?
