The safe dialer, invented by the Canadian company Intralock Tools, some years ago and distributed by Lockmasters in the United States, was responsible for a panic scare in federal government agencies. Because of this, a commissioning of a group of experts was created to research and develop a high level safe combination lock capable of resisting the opening efforts of this machine.
In the beginning, the first model ITL-1000, had very low torque and stopped turning when trying to progression the Mosler 302 manipulation resistant locks.
Once redesigned to overcome the resistance of the MR-302 anti-manipulation function, the tool was now marketed as the ITL-2000. From this moment on is when the US Government really entered panic mode. The seed for what was to become the Mas-Hamilton X-07 had been planted.
HOW LONG DOES IT TAKE THE SAFE DIALER TO OPEN A MECHANICAL SAFE COMBINATION LOCK?
This question is absolutely impossible to answer, all depends on the locks combination. A lock with a combination of 30-60-90 will open much faster than one having a combination of 90-60-30. It all depends on the first number, the lower the number the sooner the lock will open while the higher the number, the later the lock will open.
DOES THIS EQUIPMENT OPEN ALL THE MECHANICAL COMBINATION LOCKS USED ON SAFES?
The safe dialer is designed to only open single function combination locks. These are combination locks that stop their rotation to the right when the bolt is fully retracted into the lockcase and that have no other additional steps like pushing or pulling on the dial.
ASSUMING ONE HAS THE CORRECT LOCK, CAN THE EQUIPMENT ALWAYS OPEN IT?
Not necessarily. I would say the success rate is 90%. In a standard default progression of 2 number increments.
IS THE SAFE DIALER EASY TO INSTALL AND USE?
I would say yes, the thing here is to have the necessary patience to do the initial calibration as precisely and exactly as possible. Follow the instructions in the manual to the letter.
IS THERE ANY EVIDENCE OF ENTRY LEFT BEHIND BY THIS PARTICULAR OPENING PROCEDURE?
This equipment submits the combination lock to a really intense wear and tear workout. The worn lever nose and the brass dust inside the lockcase are clear evidence of a surreptitious entry even for all those starting out in forensic locksmithing.
SET SPEED - Selects the dialing speed: 1, 2, 3, & 4.
SET DROP - Programs basic settings such as:
DROP IS AT - Here we tell the safe dialer which is the right contact point with the dial reading.
OFFSET IS - Tolerance margin above and below the contact point.
CHECKPOINT IS - Distance the dial travels to the right to test lever nose and drive cam engagement.
DIALING STEP - Selects the increments that can be used in the progression: 1, 1.5, 2, 3, 4 & 5.
SET UP - Takes the robotic hand to align with the contact point. Also serves to adjust advanced settings such as:
FIXED INCREMENTS - Adjusts a partial (custom) progression to a given wheel.
AUTO INCREMENTS - Adjusts a complete (default) progression to a given wheel.
PRESET - Adjusts a specific number to a given wheel.
LEFT RIGHT - The standard dialing sequence starts to the left. In the old dialers this button does nothing, the new dialers have this button activated to initiate dialing rotation in any direction.
DIAL - Runs the robotic hand that makes the dial turn.
COMBO - Reveals the combination dialed when the lock opened.
CLEAR - Changes the existing screen to ready and/or corrects wrong entries.
RESET - Returns all non predetermined values to default.
DIALING COMPLETE - Indicates that the dialing rotation has been interrupted. It could be that the combination was found or that the mechanism has jammed.
DIALING COMPLETE DROP NOT FOUND - Indicates that the dialer has run the complete progression and the combination was not found.
READY - Indicates that the safe dialer is ready to run. If we come back the next day and see this, its indicative that there has been an interruption of electrical power and that the machine has restarted.
Things to keep in mind
The progression in two number increments sometimes is too wide, it will jump the number and not open the lock. If this happens, we have to redo the progression in 1.5 increments.
Once the adjustments are made, the calibration of the tool with the safes dial is of extreme importance.
The axis of the robotic hand has to remain perfectly perpendicular to the door surface: up - down / left -right.
Its recommended that you do repetitive tests before leaving the dial running. I usually remain and hour doing adjustments before leaving the premises.
Its imperative that you make sure that the robotic had of the safe dialer runs smoothly and does not jam.
LUBRICATE GENEROUSLY WITH WD-40
Depending on the time that takes to find the combination, the safe dialer with submit the lock to a wear and tear it has never see in its life. Its very important to blow compressed air between the dial and dial ring before lubricating with WD-40. Is the safe is relatively small and/or little weight, you can try to put it with the door facing upwards, this position is optimum, since it makes the lubricant penetrate better and not running.
WARNING SIGNS - I always place a paper with the warning DO NOT DISCONNECT near the electric outlet that feeds the dialer and another paper with the warning DO NOT TOUCH on the safe door where the safe dialer is running.
OPENING ASSISTANT - I have the custom of always having the custodian as an opening assistant. This is the person that will keep me informed at all times regarding the dialer once I abandon the premises.
KEYPAD COVER - I always prepare a small piece of cardboard that covers the keypad completely except for a small hole where you can see and touch the combo button. This is the button you have to press to retrieve the combination. This way, when I instruct the assistant to get the combo, there is no way possible that he makes a mistake, by pressing another button and ruining the work. Once he informs me of the combo, I write it down, then I am relaxed.
BATTERY BACK UP - Its very important to install a battery back up like the ones used with computers to prevent work loss due to an interruption of electricity and to prevent that equipment damage from voltage fluctuations.
SECURE PREMISES - This is extremely important, because it can prevent that this very expensive specialized tool is subjected to vandalism or theft.
