How to use luggage lock ?

Generally, the initial password is 000.
If you want to change the password, then you first adjust the password to 000, and then use a toothpick to insert a small button in a small hole. After knowing it, you can change it to your own password, such as 123. After the change, take out the toothpick, and then flip the unlocking switch as the password confirmation. At this time, you will hear a click, the small button pops up, and the password is set.
If you want to change it, just follow this step and do it again, just change the password to your own password instead of the initial password.
