The invention discloses a coded lock with a remote monitoring function, which is provided with a mechanical lock head, a lock tongue locking mechanism, input equipment, a control circuit and a handheld card reader. The control circuit is provided with a control module, which is electrically connected to an industrial personal computer, a detection module, a main system analysis module, a standby system analysis module and a common fingerprint acquisition module; the industrial personal computer is electrically connected with the input equipment and a background monitor system; when the common fingerprint acquisition module is used under normal conditions, fingerprint information is transmitted to the background monitor system through the industrial personal computer, then the background monitor system is used for transmitting a dynamic password to the control circuit for judging, the lock tongue locking mechanism is driven by the control circuit, and finally, the unlocking is finished by dialing a plate. When the unlocking task cannot be finished by using normal operation procedures, the unlocking is finished by using standby operation procedures. The coded lock with the remote monitoring function, disclosed by the invention, has the advantages of functions of standby unlocking, real-time feedback of lock status and remote identity authentication, high safety performance of passwords and capability of realizing intensified management.
