The invention relates to an electronic lock control system, a control method and an electronic failure removing method thereof, and aims to solve the technical problems that conventional like electronic locks are poor in energy-saving effect and difficult to unlock after failure. The control system comprises an electronic control part and a mechanical control part, and the design feature of the control system is that the electronic control part comprises a power supply and a control switch controlled by a signal source; the mechanical control part comprises an electromagnet, a mechanical lock and a lock cylinder switch acting while a mechanical key is inserted into the mechanical lock; the power supply, the control switch, the electromagnet and the lock cylinder switch are in a serial connection to form a control loop; the electromagnet and a lock cylinder of the mechanical lock are in interlocking under the electrifying condition; and in an initial state, the control switch is in a closure state, and the lock cylinder switch is in an off state. According to the electronic lock control system, the control method and the electronic failure removing method thereof, the structural principle is simple, the control mode is reliable, the power is saved, even though the power is used up, the mechanical lock can still be used for unlocking, so that the electronic lock control system, the control method and the electronic failure removing method thereof are suitable for being applied to control systems of various types of electronic locks or improvement of the control modes of the electronic locks.
