A locking system and method for a movable freight container door comprises an electronic module and a mechanical lock element. The mechanical lock element comprises a shaft, at least of portion of which is configured to be inserted through an aperture in the electronic module, across a door handle retention region, and into a cavity in the electronic module. The shaft is securely retained in the electronic module by moving a lock mechanism to a locked position. At least one magnetic field sensor in the electronic module is used to read the position of the shaft in the cavity by sensing or not sensing one or more magnets in the shaft. A wireless communication component in the electronic module wirelessly transmits magnetic field sensor information. |
