How to open a Mosler safe with combination?

[Ignoramus32441]

I purchased this Mosler safe. As you can see, it is open and empty, so
there is no hanky panky going on:

http://igor.chudov.com/tmp/Mosler-Safe/

The combination, as written on the masking tape stuck on the safe,
slightly modified to preserve all numbers order, is as follows:

R 63
L 47 3 turns
R 25 2 turns
L to 0

However, the safe would not open. I was once shown that the combo
works, however, I cannot redo it. The safe is still open and I would
like to figure it out.

If anyone can help me, it will be GREATLY appreciated!

Thanks, guys!

Where are you starting from? I think you may need to spin it L a couple
turns to line all the disks up at the starting point before the first R
63.

[Steve W.]

Mosler usually has a set number of turns on the first number as well.
Plus the directions shown look backwards.

Try Left 4 turns to 63, Right 3 turns to 47, Left 2 turns to 25 then
right 1 turn to 0 continue turning to the right till the dial stops and
you can open the safe.

The "turns" can be a bit misleading. I have had to deal with dozens of
different flavors of locks over the years, and here is how MOST of them
work:

Start by turning the dial clockwise (R) 3 or 4 times to get everything
engaged internally. Stop at 63.

Turn the dial counterclockwise past 63 twice and stop at 47.

Turn the dial clockwise past 47 once, and stop at 25.

Turn the dial counterclockwise to 0.

Here's where it can get tricky. Some locks will just open at this point.
Some of them you can feel something going on internally as the mechanism
drops into place, and then you can open it. Wiggling the dial a tiny bit
can encourage this event. Others, you actually have to backtrack
clockwise a few digits to actuate something internally.

I've had success in contacting the lock manufacturer for instructions,
and alt.locksmithing can certianly set you straight.

As Richard Feynman showed, a 3-digit safe can be unlocked in minutes
even if you don't know even one digit of the combination. 5-number
combo safes take a little longer, he could usually get them open in
an hour!

[Steve W.]

It isn't that hard to change those IF you needed to (I would since the
original owner knows the current combination)
You need the correct change key and the correct directions. Or just pay
a smith to change it.

Turn the dial to the right at least three complete revolutions.

Stop at 63.

Turn the dial to the left. Stop the THIRD time that you get to 47.

Turn the dial to the right. Stop the SECOND time you get to 25.

Turn the dial to the left. Stop the FIRST time you get to 0.

Then turn the handle and see if it opens. If not, continue to the left
and the dial should stop within a short portion of a revolution. Then
turn the handle to open the safe.

DO NOT CLOSE THE DOOR until you have been able to successfully open it
several times in a row with the door open.

[Ignoramus32441]

Thanks. I will definitely consider it.

I am also thinking, what should I do with this safe, in the sense of
bolting it down. How is that properly done. It weighs only about 600
lbs and is in a place with pallet jacks and forklifts. Someone could
just forklift it out of there.

Just to be clear, I am not anticipating storing any high value stuff
in there, but I like to do things the right way, so I want to know how
are safes properly secured.

Now, regarding key: the safe has a key hole in the lock. I do not have
that key, and the safe seems to open and close without the need for
any key. So, what is the purpose of that key? For changing
combination? Is that what you were referring to?

Thanks

The key is to change the combination, and depending on the model it can
be set up to open the safe as well.

As to securing it. Figure out where you want it. Make a template of the
hole pattern in the base. then drill holes and use anchors to secure it
to the floor.

If you were doing new construction you would do a bit more, like install
hardened J bolts in the concrete, install ceramic/steel sleeves over
them. Bolt the safe down and then tack the nuts in place. Then float
concrete in around the base as well. Some do even more like adding
plates below the safe and walling it in with steel/ceramic/steel
composite plates.

[Pete C.]

When anchoring things to concrete, think Hilti. The wedge type anchors
are good as are the threaded insert type, you can't remove either type,
but you can fill them in or grind them flush if you remove the safe
later. FYI after the Boston tunnel started dropping ceiling slabs and
killing people, they called in Hilti to secure the ceiling panels
properly.

The change key hole is inside the safe on the inner surface
of the lock case... That is what you need if you want to
change the combination of the lock...

If you are referring to a keyhole in the dial, that is to lock
the dial so that without the key it won't be engaged to
spindle to prevent someone from casually playing
around with it... It doesn't and won't stop someone
who knows what they are doing as far as safe cracking...

The key hole that I was referring to, is not in the dial, it is in the
handle that opens the lock once the dial is correctly dialed.

I thought that there are very few truly professional criminal
safecrackers left nowadays, unlike, say, in 1920's or some such.
The prosession sort of died out, kind like pike pickpockets are dying
out due to "cashless economy".

Is that right or wrong?

Such a keyhole in the handle is a secondary means of security

securing the safe between uses without having to dial the
combination in each and every time... Look at how a "day gate"
is used on a bank vault so that the main vault lock does not
have to be operated every time someone needs access to
the vault...

Very very wrong...

Why do you think safe designers keep improving the materials
and mechanics/mechanisms used to secure the contents of
safes...

In the 1920's fun technology like plasma cutters didn't exist
which would cut through an old safe like a knife through
warm butter... In the olden days safes used to use chemical
warfare like tear gas cylinders and such in the doors to
deter people from drilling or blasting them open...

As far as pickpockets being a dying breed you are sounding
like you are not from anywhere near a big city, pickpockets
still exist and still lift wallets and other things from pockets,
backpacks and purses that are wallet sized like cell phones,
iPods and such... A wallet in a "cashless society" is often
worth quite a bit more than a wad of cash in the first few
hours after it is stolen yet before the owner can report all
the stolen cards to each bank because basically no one
keeps a list of all that information handy and the person
has to go home to get all the account numbers and call
customer service from the numbers on the account
statements...

Identity theft is something on the order of a $40 Billion
with a B dollar a year "industry" in the United States
alone...

I believe that this combination lock (based on the photo of the
front panel of the safe -- actually a security file cabinet) is of the
kind where you disassemble it, and change the relation between the hub
and the outer disc (where the notch is to allow opening when all are
lined up). It also does not have the tumbler in the middle of the
combination dial to switch from dialing mode to the retract the bolt
mode. So this one would not have a change key, unlike the Sargent &
Greenleaf ones. (It is a vintage device, FWIW.)

No -- the keyhole in question is not in the dial, nor in the
back of the lock (which was not shown in the photos linked in the
original question). Instead, it is in the center of another section to
the left of the actual combination dial. This section is what withdraws
the bolts in the door -- when allowed by the combination lock having
been properly dialed. And the key simply keeps the withdrawal lever
(actually two wings on either side of the keyhole) from turning -- or
totally disconnects it from the bolt withdrawal mechanism. Without my
hands on the device in question, and considering the one which I had was
left behind in the apartment storage room about 1975, I can't check it. :-)

But it, like this one, has the door designed to slide back on
tracks into a cavity beside the actual file cabinet, so it is out of the
way during normal daytime access to its contents -- at the cost of the
whole thing being a little wider than the more common Diebold security
file cabinets which were at work before I retired.

Enjoy,
DoN.

The key locking dial has several functions intended, but this is the
first I have heard of the casual play theory.


the first function is to day lock the safe. This is used when some
one is in and out of the safe all day long and wants to keep it
locked, but does not want to re-dial the combo each time.


A secondary use is on a drop safe serviced by an armored car company.
The merchant has the combination to the dial on the drop side of the
safe but is not issued the key, so the cash stays secured in the event
of a hold-up.

BULLSHIT!!!

If there was, you would have had at least seven threads here asking
what kind of gun:
1: How to mount it.
2: What gauge of wire to use.
3: Whether you should use a servo, solenoid or stepper motor. This would
spawn multiple sub threads, as well.
4: What metal to make the mount with.
5: Where to get the cheapest bullets.
6: How to make it self destruct before the police arrive.
7: How to explain why someone broke into your building and shot
themselves several hundred times, along with all the damage to the safe.

Turn the dial to the left at least four complete revolutions.

Stop at the first number of the combination.

Turn to the right and stop on the second number the THIRD time it appears.

Turn to the left and stop on the third number the SECOND time it appears.

Turn to the right and stop on zero. If there is a small inner knob in
the middle of the dial turn it all the way to the right. Then continue
turning the dial to the right until it stops.

If no small inner knob, then turn the dial to the right until it stops.

Take the cover off the lock and see what numbers the gates line up under the fence at. If you can't figure it out this way on your own, no amount of instruction is gonna help you. If the lock is Mosler, which is by no means assured, then the wheels probably run in back to front order. The rear most wheel in the pack is dialed first and so on back to front. Most other modern safe locks work the opposite way with the wheels being dialed in order front to back. S&G Ilco, Lagard will all work in the latter manner.

Call a safe tech. Moslers are almost all fairly serious safes, especially any you would find in government use like in a PO. If you really forgot the combination you probably aren't getting in without doing a lot of damage unless you have some expertise.

Hello-
I was wondering if you could recommend anyone in Indianapolis, IN who could open a Mosler safe.
It is part of my father's estate and we do not have the combination.
It is a Big steal blue safe, about 4x2x3.
I have not found any specific numbers on it to identify it better.
Any input on how to proceed would be a great help.
Thank you so much!

My best advice would be to find a SAVTA (Safe And Vault Technicians Association) certified safe technician through the SAVTA website http://www.savta.org/savta_tech.php you can enter you zip code and find someone qualified and local. For a city the size of Indianapolis you should have a few to pick from...

Hello, and I probably won't be of much help but the built-in Mosler
safe/security cabinet combo locks (at least the ones used by the U.S.
Gov't) that I'm familiar with go L-R-L with another right to the dial
stop position to enable retraction of the bolt. Once the container is
unlocked the combo dial can't be turned until the cabinet drawer (or
door as applicable) is closed. The dial then needs to spun several
times in the same direction to ensure the enclosure is completely
secured. Those Mosler locks worked opposite to the more widely familiar
R-L-R dialing order. Sincerely,

Yes but you are going to need the help of a locksmith that does safe work. If the safe is open, it will not be too difficult. If the safe is closed, it will need opened first. A locksmith that does safe work should also be able to get the original combination for you.

Yes, but I'd recommend taking it to a professional. It's what's called
a hand change lock. Inside the case are wheels, sort of like gears,
that can be aligned in different ways to set the combination. I advise
a professional because it's a precision mechanism with many small
parts, and also there are certain combinations that should not be used
due to mechanical limitations, called the forbidden zone. Lock and safe
technicians are familiar with all of this.

This type of work is much cheaper if you take the safe, the door, or
the lock to the locksmith rather than having them come to you. Look for
a brick-and-mortar local locksmith that works on safes and vaults,
ideally an old-school establishment.
