Claim:
1. A lock control method, comprising: sending, by a remote control module comprising a remote controller and a signal transmitter located separately at two different locations, an activate signal to an access control terminal via a first channel by using a telecommunication technology, the first channel being selected according to an operating time provided by a clock of the remote controller; activating an authorization process by the access control terminal when receiving the activate signal via the first channel; generating a rolling code key by the access control terminal, the rolling code key being dependent on an operating time provided by a clock of the access control terminal; sending the rolling code key to the remote controller of the remote control module via a second channel by using the telecommunication technology, the second channel being selected according to an operating time provided by the clock of the access control terminal; inputting the rolling code key in a rolling code generator of the remote controller so as to generate a rolling code by the rolling code generator according to the rolling code key and data obtained from the remote controller, the data being dependent on operating time provided by the clock of the remote controller; sending the rolling code from the remote controller to the signal transmitter; sending a control signal including the rolling code from the signal transmitter to the access control terminal via a third channel by using the telecommunication technology; receiving the control signal from the signal transmitter by the access control terminal; and unlocking a switch and/or a lock by the access control terminal when the control signal and the rolling code are verified by the authorization process to be consistent with a predetermined rule; wherein the clock of the remote controller is synchronized with the clock of the access control terminal.
