A lock control method, comprising the following steps: sending, by a remote control module comprising a remote controller and a separate signal transmitter, an activate signal to an access control terminal via a first channel by using a telecommunication technology, the first channel being selected by a first channel selector of the remote control module according to an operating time provided by a clock of the first channel selector; selecting, by a second channel selector of an access control terminal, the first channel according to an operating time so as to receive the activate signal via the first channel; activating the 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 second channel selector 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; 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; sending the rolling code wirelessly from the remote controller to the signal transmitter; selecting, by the first channel selector, a set of third channels according to the operating time so as to send a set of control signals sequentially to the access control terminal via the set of third channels; 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; selecting, by the second channel selector, the set of third channels according to the operating time so as to receive the set of control signals sequentially via the set of third channels; 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 first channel is different from the second and third channels and the clock of the first channel selector is synchronized with the clock of the second channel selector. sending, by a remote control module comprising a remote controller and a separate signal transmitter, an activate signal to an access control terminal via a first channel by using a telecommunication technology, the first channel being selected by a first channel selector of the remote control module according to an operating time provided by a clock of the first channel selector; selecting, by a second channel selector of an access control terminal, the first channel according to an operating time so as to receive the activate signal via the first channel; activating the 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 second channel selector 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; 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; sending the rolling code wirelessly from the remote controller to the signal transmitter; selecting, by the first channel selector, a set of third channels according to the operating time so as to send a set of control signals sequentially to the access control terminal via the set of third channels; 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; selecting, by the second channel selector, the set of third channels according to the operating time so as to receive the set of control signals sequentially via the set of third channels; 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 first channel is different from the second and third channels and the clock of the first channel selector is synchronized with the clock of the second channel selector.
