Anonymous users2024-01-23It seems that you have made a serious mistake like most people, changing the lock is a big thing, not just a lock seller can be, the store that can change the lock must be filed with the public security bureau, and obtain a business license, not to say that any store can be changed. My family has just changed the locks, and I found a license, so that there is security. Hurry up and check if the store that will help you change is qualified, and if you're unlucky and he doesn't, then hurry up and change it again.
