The user does not need to change the password to prevent the previous user from entering again, which improves the safety of another user\'s residence. Its use can reduce the trouble caused by changing locks, save costs and improve safety. Based on the design of multi-user password lock, the AT89C51 single-chip microcomputer chip is introduced, and the hardware design and software design content of the multi-user password lock are given.
