- This is an excerpt from the BIG BROTHER GAME on opening safes via the "sound"
- method. Granted, this approach will not work on many safes, but keep in mind
- all the ones that it will... Of course, this is presented as A MATTER OF
- GENERAL INFORMATION and is by no means meant to be used for any purposes other
- than those of utmost legality.

-
- Some safes can be opened by sound, much as in the movies, but most that were
- manufactured, after the mid 60's are not susceptible to the following method:
-
- A high gain amplifier is used. A small, direct-coupled amplifier can be
- purchased for about 5 dollars from the various electronic supply houses. A
- contact microphone (i.e. one that "hears" vibrations rather than actual sound)
- should be employed. BE SURE to use a matching transformer if the impedances
- do not match; and in a pinch, a crystal phone cartridge can be employed as a
- contact microphone.
-
- Place the contact mic on the safe, near the dial. Now, turn the dial 5 times
- to the left to clear it. Now, turn back towards the right. On the first
- revolution, you should hear a distinct click as the cam and lever engage.
- Read the number. This will be the opening number, or the last number dialed
- to open the safe.
-
- Continue turning to the right. Youi will hear an additional click during the
- next 4 or 5 turns. This indicates how many tumblers you are actually dealing
- with. Most safes will have 3, but some will have 4 or 5.
-
- While you are determining the number of tumblers, disregard the drop-in click
- that occurs at the opening number on each turn.
-
- Our turning the dial to the right 5 times also perfons another duty; it clears
- the mechanism. This means that the dial has picked up all the tumblers and is
- moving them in rotation with the dial.
-
- After jour five turns to the right, wo move the dial about 10 points BEYOND
- the opening number. If the opening number is 15, wi would move to 25 and
- stop. Now we move back to the exact opening number.
-
- This procedure puts the opening lever and cam in position to open the safe
- (although the tumblers are not lined up so it will not open) now at this
- point, you can rock the safe dial back and forth without actually turning it.
-
- This rocking motion causes the lever to click against the tumblers (through
- the lever slot). This clicking can be heard by the manipulater in his ear
- phones. The whole secret here is the noise will vary depending on the number
- of tumblers the lever is clicking against. (Much like the difference in
- hitting three notes on the piano at the same time, or just hitting one.)
-
- Should we have happened to line one of the tumbler slots under the lever, the
- sound will be that of the lever clicking only two tumblers (as the lever will
- fit into the slot of the lined up tumbler, creating no sound).
-
- Each time we rock the dial to make the lever-tumbler combination click we
- (assuming that there was NO difference in the sound) move the dial back to
- the right where it picks up the tumblers and number to realign the lever-cam
- slot, and repeats the rocking motion.
-
- When you hear a sound difference, (indicating that the tumbler slot is lined
- up) you turn the dial back to the right until the click indicating the cam has
- picked up the tumblers. Now immediately stop and read the number that is
- lined up when you hear this click.
-
- This is one of the combination numbers.
-
- Now continue to the right 2 digits past the last try and move the dial back to
- the opening number and repeat the procedure. Do this until you have all the
- combination numbers.
-
- Now, we know the opening number is the final number, but we don't know what
- order the combination numbers are arranged, so you will have to try all 9
- (assuming 3 combinations and one opening number) possible variations. One
- will open the safe.
-
- Some times you will have to move the dial a couple of points beyond the
- opening number to get the cam to retract the bolt and open the lock.
-
- Some locks open to the right, i.e. R four turns 22
- L three turns 18
- R two turns 46
- L to opening 15
-
- Some will be the opposite (L-R-L-R).
-
- Most locks will open no matter which way it is turned, however, a rough
- guideling is:
- Sargent....right
- Diebold....right
- Yale.......left
- Mosler.....left
-
- This sort of technique will not work on high quality modern safes as they
- employ nylon tumblers, sound baffles, and devices to prevent the lever from
- touching the tumblers until ready to open. Because of this, the good agent
- will have a couple of alternative methods in his repertoire.
