There are many different ways a combination lock can be built, the two most common are the "dial" and the "disk" construction. In both types rotating "tumblers" must become aligned so that an unblocked slot through the stack of tumblers allows the "bolt" to slide and unlock the mechanism.
You can crack a 3-digit combination lock by sequentially trying every possible number. Writing down and keeping track of every number used will help avoid confusion and speed up results.
Start dialing. If it's a three digit lock, then you can try all the possibilities in a reasonably short time. If it's a four digit lock, then it will obviously take longer, but it's still something a diligent person can manage in an afternoon. (If you try a combination per second, which isn't that hard, you can exhaustively search out a four-digit combination in at most 3 hours.)

There are 15180 combinations.
You should try out all of the three-digit combination. There are 10x10x10 = 1,000 possible combination (assuming digits 0-10).

6 x 7 = 42 (it helps to know the multiplication tables), so the prime factors are 2 x 3 x 7, and the combination is 237
If the case is new 0-0-0 will open it. If not you have to crack the combination which is not to difficult on a three digit lock. start with likely number sets if that doesn't work srart counting up from 000 to 999, it can't take that long.

To reset an Echolac 3-digit number lock, you typically need to follow these steps: Set the dial to the current combination (if you know it). Press and hold the reset button on the bottom or side of the lock. While holding the reset button, set your new desired combination. Release the reset button to save the new combination. Please refer to the specific instructions provided by Echolac for your particular lock model for accurate guidance.
maximum of 1000 combinations (10X10X10). Work with one lock and set it to read 000 . Count upward to 1000 by "ones". As you turn combination dial up with one hand, test if lock opens with other hand. Takes about 5 minutes and hopefully both locks are same combination.
slide the open button to the right hold and while holding it there , change the combination to what you like and release , u new combination is set.

30.The first digit can be one of three digits {3, 6, 9} corresponding to the last digit being {1, 2, 3}, and for each of those three digits, the middle digit can be one of ten digits {0 - 9}, making 3 x 10 = 30 such numbers.It is assumed that a 3 digit number is a number in the range 100-999, excluding numbers starting with a leading zero, eg 090 is not considered a 3 digit number (though it would be a valid 3-digit number for a combination lock with 3 digits).
Hi, I have the instruction for the sesamee lock . Send me your address and I will mail you the same. jmc@jimculligan.com
If you don't know the code to the combination lock then your stuffed. Just go through all the possible combinations and unlock it (only if its a 3/4 digit) On the other hand if you do know the code and want to change the lock, hold down the unlock button/lever and change the digits and that should change the code.
