A system for determining a state of a door having a locking mechanism for locking the door includes a locking mechanism and a door sensor. The locking mechanism sensor is disposed for sensing a condition of the locking mechanism and generating a signal indicative thereof. The door sensor disposed for sensing a condition of the door and generating a signal indicative thereof. The system further includes a processor for determining a state of the door, in response to the signals from the locking mechanism sensor and the door sensor. The state of the door is a secured state when the door sensor senses the condition of the door as closed and the locking mechanism sensor senses the condition of the locking mechanism as locked. A method for determining a state of a door having a locking mechanism for locking the door includes sensing a condition of the locking mechanism and sensing a condition of the door. The method further includes, determining a state of the door as a secured state when the condition of the locking mechanism is sensed as locked and the condition of the door is sensed as closed.

Electronic access control of a seldom-used outdoor security enclosure, such as a key vault, is provided by a vault lid and key system whereby the procedure for opening the enclosure occurs in two stages. One stage is a low-force stage provided by electromechanical mechanisms housed within the lid and energized by a relatively low power source. The high-force stage is provided by a human operator applying manual force to open the lid. The system is particularly adapted for security enclosures that are exposed to an outdoor environment and not operated for extended periods of time.
