  • Publication number: 20020008609
    Abstract: An electronic frame lock includes an electronic lock and an electronic key. The electronic lock is formed of a controller, a motor, and an insertion pin. The motor receives a control signal from the controller, so as to pull or push the insertion pin to bring about the unlocking or locking effect. The electronic key transmits a signal to the controller of the electronic lock. As the signal is compared and verified by the controller, the motor is started to pull the insertion pin, so as to unlock the electronic lock.
