Locksmithing/cole comb. lock



I purchased a business that utilized a Cole File cabinet that has combination safe behind a keyed door. The safe is open and the former owner of the business never used it because he did not know the combination.  

Is there a way to figure out the combination? On the inside of the door there is a hole where you can see something spinning when you turn the safe dial and this "wheel" that you can see spin has a notch that appears periodically.

Please help if you can, Thanks, Ted.

Hi Ted,

The little "peak hole" in the rear of the lock is how you determine the combination that the lock is currently set on.

Using the dialing sequence, you will observe the wheels as they pass in the peak hole.   When a wheel gate aligns in the hole, you need to observe the corresponding number on the dial, at the 12 o'clock index mark.
After you obtain the numbers for each wheel, you should be able to successfully dial it open.

The dialing sequence should be:

4 times left to the first number (first wheel you can observe)
3 times right to the second number (next wheel)
2 times left to the third number (furthest wheel in the peak hole)
1 time right until the dial stops - the lock bolt should be fully retracted at this point.

While you can note the final number as a reference point - this number won't change.

Note:   Left is counter clockwise, Right is clockwise (observing the dial).    Do not count the revolutions of the dial, count the individual number as it arrives at the 12 o'clock index mark.

If you have trouble with these instructions or still can't obtain the combination, then I would recommend having it checked out by a safe technician from a local safe company.    Have them check the lock out to ensure proper operation, and recover or reset the combination for you.

Hope this helps.
