¿Cómo cambiar la combinación en el candado?

In most cases of combination padlocks, the change mechanism is the same.

1. The correct code is set (so as to open the padlock)
2. The padlock is opened and the "shackle" rotates 180 degrees
3. The shackle is pressed in (in some padlocks you have to press all the time, in others not)
4. change the code
5. Remove/release the shackle
6. And done.

An example for another padlock model is, among others, in this video:

I must say i have never seen a single person changing it. You don't even have a reset button.

To change the combination of a padlock, you must first set the padlock to its current combination. Then turn the knobs as much as needed to reach the new combination. It is important to remember the new combination so that you can open the padlock in the future. After setting a new code, you should test the padlock to ensure that it has been reset correctly.

The best double keyed padlock. Breaking the code takes 10-20 seconds.
