The way a combination lock works is so simple. All you have to know the combination, after that everything becomes so easy and you become a pro after few openings and closings — there are a few turns to the left and right, and voila — the lock is open! Let’s get started to know how to open a lock, just follow these steps.
Part 1 : Getting the Combination Lock
Get a combination lock.
Combination locks are available at every medium sized to big hardware, home improvement, or spare parts stores across the world. You can buy them from a nearby hardware store to a world renowned ones like The Home Depot, Lowes, Sears, Modell’s, Staples, and Walmart.
Always find the combination on the sticker on the back of the lock.

Most of the time, the new combination lock’s unique code is given on the back sticker of the lock. Remove the sticker carefully. Write down or memorize the combination and throw out the sticker after tearing into bits — you never leave the sticker around. It will be complete mishap if someone finds it and gets to know it’s the combination to a lock.
Start memorizing the new locker combination.
This will definitely easier for you to get the work done fast and open the lock.
Part 2 : Opening the Combination Lock
Turn clockwise the dial on the lock three times.
Turning the dial to the right for three times clears the lock and helps it reset so that it’s ready to open.
When the marker points to the first number of the combination, stop turning.
There is a marker or line that can be perfectly seen at the top of the dial, which points to the twelve o’clock position. More often, it is found to be red. For example, the first number on the lock’s combination is 63, therefore you should stop turning the dial as the marker points come to that number.
Turn the dial back to the left for one full turn.
Turn anti-clockwise one full 360 degree turn, go past the first number (63), then now stop at the second number— let it be 20.
Turn the dial to the right.
For the last time, again turn the dial clockwise and stop at the last number on the sticker—6.
Open the lock.
Try to pull up the shackle gently at the top of the lock, and it will open the lock. You may also stick to the shackle and pull down the lock. If, in case, it doesn’t open, redo the process from the start. After partially engaging the tumblers, you must clear out the lock before giving it another try.

Part 3 : Locking the Combination Lock
Insert shackle.
Turn the shackle 360 degree so as to open part is above the hole, and push it a bit into the opening at the top of the lock.
Spinning the dial.
Turn the dial in whichever direction you like, for three turns. No need to be concerned about the number you stop on. This procedure will disengage the tumblers, will make it so and you have to begin once again with the first number if you wish to open it.
Check it.
Ensure that the lock is completely locked. You may pull on the lock or shackle. If it still opens up, lock it again.
