    This is for disassembly, not unlocking. There is a saying that the lock can only prevent the gentleman but not the villain. Generally, the lock is opened in less than 1 minute in the hands of a professional person, and the brute force cracking is also very fast, so do not leave cash and valuables at home when you go out.

    Let me talk about unlocking first, let's introduce the lock first. The lock is divided into two ends, one end is used for anti-locking and the other end is used for key insertion.

    Obviously, the lock must be removed from the locked end to ensure safety.

    There will be a small hole at the lower end of the handle at the anti-lock end.

    Here is a word, pay attention to the installation direction of the bolt, if the bolt is installed upside down, the door will not be locked and the door will open with one push. Locked locks are also easier to break.

    Note that the vertical side is on the inside, which is the side that is locked.

    Someone will ask questions about the lock slot. Generally speaking, as long as the lock slot of the previous lock is not damaged, the lock type of the two locks is the same, and there is no problem if it is not replaced.
