Electromechanical lock and its operation method. The lock includes a power transmission mechanism to receive mechanical power produced by a user of the lock; a generator to produce electric power from the mechanical power; an electronic circuit, powered by the electric power, coupleable with a key, to read data from the key, and to issue an open command provided that the data matches a predetermined criterion; an actuator, powered by the electric power, to receive the open command, and to set the lock in a mechanically openable state; and a threshold device to control the power transmission mechanism so that a mechanical tension rises until a predetermined force threshold is exceeded, whereupon the mechanical tension transforms to an action producing the mechanical power received by the power transmission mechanism. |
